Greensands Ridge Relay GSRR – Mini ultra on knackered legs

This is an event I’ve wanted to run for many years. It’s a small deal, held locally, running from Leighton Buzzard to a village outside of Bedford. No medal, no goody bag, no expo to collect your number, no cotton t-shirt that doesn’t fit anyone.

I much prefer small friendly events put on by runners, for runners, as oppose to corporate greed machines (if a race has the word “great” in it, it’s typically referring to the price and the profit margin). GSRR is geared up to be a relay with six legs of varying lengths and has a great club atmosphere. Lakeside Runners normally enter some teams and any from the Late Group are legendary for getting so hideously lost we miss cut-offs and get disqualified. It appears to be a combination of lack of recce runs and sheer inability to follow a simple map. Rumour has it some of the team members are still living in the woods of Millbrook, having gone feral and surviving mostly off road kill. They’re now too far gone to capture and attempt to rehabilitate in society. The Early Group actually mange to finish most years as they’re not idiots.

Speaking of idiots there is an option to run the whole 34 miles solo as long as you have a team from your club entered into the relay as support. It’s not an accepted marathon for the 100 Marathon Club since the rule excludes anyone not part of a club and 100MC are all about inclusivity. This is one of the reasons I’ve never run it before as spending a full day running a race that didn’t get me closer to the 100 wasn’t a good use of a permission slip from the wife. Also until recently I never wanted to run over 26.2 miles as it’s stupid.  I’ve now been led astray on ultras and run events where 34 miles is the home straight, and I’ve passed the magic 100 so neither was an obstacle anymore.

Preparation – The route follows the Greensands Ridge. In theory it’s well signposted and easy to follow. The organisers do a great job of providing a single page map of each stage with helpful comments on. Given the already mentioned issues I was keen to get some recce runs in though and in a very condensed post-GUCR 145 couple of weeks I managed to run legs 1-2 and 4-6, having already run leg 3 a couple of times just as a decent trail run in training previously. Even the recce runs take some planning as you’re either stuck with an out and back which can end up 18 miles, or needing to faff about with cars at either end. Fortunately the usual MK suspects were also entered to run so we had as many as 8 idiots meeting at 6am each Sunday to practice the route. The runs were great although I was finding even keeping a 10 minute mile pace a lot harder work than I expected but put it down to still recovering from the GUCR so hoped to bounce back on the day in race mode.

Route – I’m not great with navigation so after each recce run produced some notes to accompany the maps. These are all available HERE for anyone that wishes to use them. Feel free to comment if you find errors or think they could be improved “Hey Mark, I got lost on that stupid fork in the path just after the farm, you never even mentioned that and I ended up lost for 4 days, missed the opening stages of the World Cup and never got to see England come home early. Oh and I also missed the birth of my child which apparently is also an issue. According to the wife.”.

Plan – Jen had a reasonable plan of 9min miles based on her previous course record. I’ve run 38 trail miles at around that pace before so it seemed possible. I’d had a few relatively low mileage weeks since GUCR so was hoping my state of recovery would match her state of brokenness from running 60 miles the weekend before at the Redway Festival of Running. Hah! An interesting quirk of the solo race is there isn’t likely to be a finish line set up before 4pm, and a target to finish of 5pm so you need to estimate a suitable start time to hit this window. We’d gone for 12 noon.

Leg Cut Off Distance Pace (min/miles) Leg Time Time of Day Ahead of cut off
1 12:00 5.6 00:09 00:50 12:50 00:39
2 13:30 3.9 00:09 00:35 13:25 00:34
3 14:00 9.1 00:09 01:21 14:47 00:27
4 15:15 5.7 00:09 00:51 15:38 00:21
5 16:00 5.4 00:09 00:48 16:27 00:17
6 16:45 4.7 00:09 00:42 17:09

Actual – Given the 9min pace was a little close to the course cut off I was glad we got to the start ahead of our 12 noon intended time and got underway at 11:36, giving an extra 24 minutes which I might well be needing. First two miles were too quick at 8min pace, we stormed through the first two stages and after an uncomfortable few miles my legs seemed to wake up and I felt good. I was in my groove and flowing nicely. I had this. Then I didn’t. In one of those ‘oh yeah I remember that….’ moments I recalled that previously post ultras I can normally blag up to around 13 miles without issue before my legs realise what’s going on and start to question what I’m playing at. Some parents let their kids act up a bit to teach them responsibility, but go beyond a certain boundary and you head straight to the naughty step for a time out which is exactly what my legs were telling me. Walking up the ploughed field on leg 3 I pulled my emergency Lucozade out my vest and downed the whole thing whilst Jen jogged on ahead. Still thirsty and with no sudden release of energy, I felt decidedly flat and watched Jen jog into the distance, a familiar sight from the SDW50. And the SDW100. And the London Marathon. And the Milton Keynes marathon. And the Tour of MK. And most Wednesday club runs. There’s a pattern here. I sort of expected to get dropped somewhere on leg 3 but not quite this soon. It was hot. I was thirsty. I was knackered and had a long way left to go and couldn’t really be arsed but my car was at the end so I sort of had to keep going.

What’s nice about the GSRR is the relay element means there’s scores of people at the checkpoint, far more than you’d expect for a small event so coming into the dodgy (and better known for dogging) car park at Milbrook I was greeted by club mates and lovely Julian thrust a cold water at me. I had food on me but struggled to eat it and was reminiscing of the aid stations at Centurion events and the bountiful supply of food and snacks. I could have murdered some pineapple or watermelon, instead made do with a squishy Mars bar from my pocket and a death march up the hill to the church.

It was about then I wished I’d packed an iPod or something as being alone with thoughts was not helping. The route was easy to navigate due to the recce runs so I didn’t even have that to take my mind off quite how rubbish this was all going. Miles ticked by at an increasingly slow rate and I started to worry about the cut offs. They were going to be close at 9min pace, how much buffer did the earlier start allow for death marching? I was bothered but also too apathetic to pull my phone out and check the times. Would being timed out be worse than dropping at the next checkpoint? I’d run 350 miles last month, stayed on my feet for 38 hours, I had nothing to prove by completing this ‘short’ ultra. I could probably blag a lift off someone at the next checkpoint. Fortunately the route started to run through the forest and I always feel better surrounded by trees. Woodn’t you? I ran on to the checkpoint to get another water off Julian (did I mention how lovely he is?), top up bottles with High 5 tablets and run on. In need of sugar I unleashed some Skittles. I couldn’t taste the rainbow, just a fly that I’d inhaled earlier and still seemed to leave a lingering aftertaste in my mouth. Onto the short section running down the dual carriageway headlong into cars (hit me I dare you, I’ll be through your windscreen like a wild moose in Canada) before crossing into woods and around the fields.

Coming into Clophill I was looking out for the pub. Still not sure how close to the cut off I was but taking the number of relay runners at the checkpoint as a sign I wasn’t yet at the back of the pack so could spare time for a drink. Even if I got timed out at least I could enjoy a pint in the sun. Luck was on my side and some amazing supporters offered me their beer which didn’t even touch the sides as it slid down. So cold, so refreshing. So best get going.

Coming towards the end of Leg 5 a combination of beer, caffeine tablets and wanting to get the bloody thing finished seemed to work and I began to pass some other solo runners. Up ahead I recognised the usual MK suspects coaxing a humourless Mark along who despite looking in good form was not having the race he wanted and uttered obscenities to all around. I’m a huge fan of excessive swearing and although taking comfort from the misery of others is pretty poor form, a certain amount of schadenfreude helped lift my spirits and we jogged in to checkpoint 5 as a happy group. All apart from Mark anyway. The others stopped at the checkpoint to perform last rights on Mark. He wasn’t looking that bad but I think SJ was minded to end him anyway, partly out of pity, partly frustration. I resolved to push on. Towards the later miles of the race the solo and relay teams had bunched and for the first time in hours I had a long stream of runners ahead to follow which looked appealing. It was a couple of days later someone mentioned our motley crew of runners were only a few minutes inside the cut-off to start the final leg so I’m thankful of starting those 24 minutes earlier than planned as I clearly needed it.

Frustratingly although I only had just over a parkrun to go I couldn’t seem to access that final reserve of (relative) speed that I’d used at the GUCR145 so made do with shuffling along, saying hello to the horses and cows for good luck and to keep my mind occupied. Not since I ran the Bournemouth marathon straight after the half marathon have I felt so empty and dead legged. For someone that runs a lot I’m bloody awful at it sometimes. Through a gate and across a horse farm ready for the final ‘sprint’ around the church which turned out not to be needed as the race finished alongside the church and not in the pub car park as I expected. Upside – less far to run. Downside – further to walk to bar.

All finished in 5h50m, 40 minutes behind target but crucially wasn’t timed out or dropped, and got a free beer. Tried to force down a burger and easily swallowed a shandy. Jen had ‘struggled’ as well and ‘only’ smashed me by 25 minutes to bag 1st place with me in 2nd.  SJ and Ellie scored joint 1st female having buried Mark somewhere in the woods. Most importantly I’d beaten club mate Lennie as he’d never of let me forget it if he’d won, especially as he’d forgotten one of his calf guards so probably ran in circles a lot. To be fair I never would have stopped ribbing him had I caught him on route despite his earlier start time.

Next year I’m going to train for shorter distances, not run 350 miles the month before, and try to sort some food on route better. Also convince Jen to run some other event instead.

Greensands Ridge Relay – Course Notes

A post as much for my own benefit so I don’t lose this in the future. Below are some written instructions to the Greensands Ridge Relay, the annual race held every June running from Leighton Buzzard to Northill.  The total route is 34.4 miles.

The race is normally held as a relay, with one runner on each leg, varying from 3.9 to 9.1 miles, or you can run the whole thing solo as a very cheap ultra (£10) if you’re member of a club that has a team entered. For this reason it’s excluded from the 100 Marathon Club as a qualifying event as precludes unattached runners.

Official website –

The official website has the maps available. In the main these are good but partly due to the scale and the lack of detail on the OS map there is still scope to go wrong. For that reason I put together the below to accompany the maps.

Grand Union Canal 145 – Helpful Hints


After my overly long blog on the actual fun of running 145 (and 8.5) miles along the GUCR, thought I’d do some advice for first timers in future to aid them in their quest.  There are a lot of blog posts about experiences but not many with simple advice so here goes.

Basics – 145 (and a bit) mile race from Birmingham to Little Venice in London, held the second May bank holiday, starts 6am Saturday with a 45 hour cut off (so 3am Monday morning). Simple point to point race so need to plan travel to start and from finish.

Entry – You need to register your interest to join the following years ballot, this is typically 1st July.  The NEW AND IMPROVED official website is here which is now a great user friendly experience. A good source of information is the FB group. The race is oversubscribed so assuming stays the same you register your interest on SI Entries website and put your name in a ballot. If you win you stump up the cash also on SI Entries to confirm entry.  Options for entry are supported (as in you will have own crew) and unsupported (you will not have a crew and require organisers to feed you).

Preparation / Training – I complete a half dozen short ultras and three 100 milers in advance of this. I felt it was enough to prepare me and I finished. After 50 or so miles the length is just a matter of slower pace, more walk breaks and making progress. The race is flat so something like Thames Path 100 is good preparation but at only 3 weeks before is a little too close. The Country to Capital Ultra features the final 10-12 miles of this race as a taster and is early Jan so good to start the training off with.

Travel & Accommodation – Once in, book your hotel in Birmingham. The race registration is normally at the Travelodge Birmingham Central, 230 Broad St, Birmingham B15 1AY. If you book ahead you can get a room for around £40. It’s a pretty noisy hotel but then anything within walking distance to the start will be on a Friday night.

At registration you need to sign your waiver, show your race numbers with filled in emergency details on the rear, and if you want to pay a £10 deposit for a British Waterways Key to access the taps and toilets on route (worth it). You can register on the morning of the race but most opt to register the night before. If you keep an eye on train offers you can get some good deals. I paid £6 for a Milton Keynes to Birmingham train and it’s about a 10 minute walk to start.

Night Before – Typically after registration most people head across the road to O’Neil’s pub opposite, meet up with other runners and if sensible drink enough beers to help them sleep through the noise of a Friday night in Birmingham. Worth noting nothing will be open the following morning for breakfast or last minute purchases so worth popping into the Salisbury opposite and buying breakfast and provision. Don’t forget water for your bottles as there is no facility at the start for topping up water bottles and it’s nearly 11 miles to first checkpoint.  Go back to hotel, set a dozen alarms and stick everything on charge (phone, battery packs, GPS watch, iPod etc).

Morning Of The Race – Assuming pre-registered there is little to do at the start other than drop your bag off (it was two bags for unsupported, recently changed to one) and eat some snacks on the start line so arriving 5:30 for the 6am start is probably sufficient.  Listen to the briefing, and then set off on a little jog. Start is at Gas Street Basin (B1 2DS) and about a 5-10 minute slow walk from the Travelodge.

Drop Bags – As mentioned above it was two bags for unsupported but in interests of keeping it sensible for the volunteers who need to lug out your bags at the aid stations it’s dropped to one. Depending on the weather your bag may well get wet so pick appropriate bag and worth having contents in bin liners and zip lock bags inside to guarantee they stay dry. Maybe a spare bin liner for sweaty, wet stinky gear. Try and pack the bag sensibly enough that you don’t need to dig through when knackered.

  • For the end of the race (put at bottom of bag)- a full change of warm clothes, comfy shoes and maybe a mains charger for phone etc. If a contact lens wearer you may want your glasses for the journey home.
  • For the race kit (keep accessible in bag)- spare shoes, socks, lots of tops/shorts and jackets, gloves and hats (it can get very cold at night on the canal), Vaseline, k-tape, headtorch(es), spare batteries, battery packs for phone and GPS watch with appropriate leads, any food items (pot noodles, sweets etc), spare paracetamol, salt tablets, gels/caffeine tablets, blister kit, plasters, sun cream, that bin bag for wet gear, iPod etc. I tended to have lots of clear bags for each group of stuff, so tops in one, cold weather gear in another etc to make it easier.
  • To carry for the race – water/fluids, food (the aid stations are far more spread than a typical ‘easy’ ultra), emergency poo kit, small Vaseline, rain coat, maps or directions, GPS watch, phone, tracker (if you have one), emergency blanket (MANDATORY), buff/hat for sun, emergency cash or card (there are cafes, pubs and ice cream vans on route), sunglasses. Cup for drinks. Some go with the rubber speedcups, personally I’d recommend a sturdy plastic camping/travel mug. If time is getting tight you can get it filled with soup/pasta and eat on the move. Would also recommend a long sleeved base layer in a zip lock bag as well as an emergency item.


Medals/Tops – Unlike most 100+ mile events the memento is not a belt buckle but a massive medal. No free finishers tee (come on the race is cheap as chips!) so you’re invited to order a tee, hoody or buff a few months before the start. Often you get the chance to order after the race as well if you feel ordering in advance would curse the race for you. If you have a crew then getting them a warm hoody to spend the night stood in the rain in is a nice touch.

Route Maps – These are pretty good and posted to you on proper waterproof paper. I’d spend a bit of time on Google Maps to check the trickier sections (tunnels and the canal spurs) so it’s fresh in your head.

I’d also recommend the excellent pacing spreadsheet on the Facebook Group produced by Paul Ali “2013 GUCR Race Plan.xls” to help plan your pacing. It also has a simple route list that is easy to follow but I’ve made a few additions to below based on my experiences in 2018, and updated for the 2021 edition as pacing a mate for some of it. Personally this laminated or in a small pouch should be all you need, with maps stuck in a your backpack as a backup. If you add a column with estimated timings as well it will help keep you on target / arrange meet ups:

– Main point to note is most of this is done off bridge numbers, some are missing or obscured so double check. Also newer bridges are often added since the original numbering and then have a suffix letter, therefore if you’ve just passed bridge 78 don’t assume the next is 79, if it looks fairly new and shiny it may well be 78A so not the one you’re after.

Pacing (Buddies) – You’re not allowed pacers but can have buddies who stay behind or beside. You’re allowed a buddy runner from Stoke Bruene and I would recommend them if you can sort some. The race gets very spread out at night and especially for women I would say either grouping up with another runner or having a buddy is a good safety tip. Also stops you walking in the canal when tired! If nothing else it can be someone to moan at so the volunteers at the aid stations don’t have to listen to you whine.

Weather – It’s the UK and you’re likely to be out there for 40ish hours so don’t assume consistent weather. In particular don’t underestimate how cold it can get at night. Most will be running very slow over night and generating little heat. I ran in 2018 during a heatwave, think about 28degC in the day but at night still needed three layers to keep warm and had a spare longsleeve base layer in a ziplock bag in my race vest as a backup. Better to carry gloves and a warm hat for the night section and not need them than freeze to death.

Technology – As much as I like to keep running simple I get very OCD about having my Garmin on. Very few models even in Ultratrac mode will last the full race so remember to pack a battery pack and lead in drop bag. Most Garmin will track whilst charging, a few won’t. Have a google of your model to check. I used a Garmin Fenix 5 in normal mode and needed to charge twice for the 38hrs it took me. This model has a stupid charger so you need to do it up around a waist band/rucksack strap and charge that way rather than on your wrist. Likewise your phone is unlikely to last the full race so think about a battery pack charger for that as well. The race is long and pretty spread out so a cheap MP3 player that takes batteries would be good to keep you going.

Distance – The race is described as 145 miles. Apparently this is taken down the middle of the canal so unless you’re in a canoe you will get a longer reading. I got 153.5 miles with only one very minor detour. It’s an ultra so not a big deal but keep the extra distance in mind as the aid station marked as 53.1 miles could well be closer to 55 on your Garmin.

The Finish – There is something oddly magical about the low key finish, by some public toilets on the canal. Unfortunately the low key nature makes it hard to see from a distance so expect the last few miles to be spent thinking “Is that the railings up ahead? No. What about now? No. Where is it, have I missed it?” until you eventually hit it. The final stretch from Checkpoint 9 is easy. You’re on the right hand side of the canal and just stay there for a half marathon until you cross the line. This sounds obvious but after 30/40hrs on your feet you may well start to wonder if you’ve missed it and it’s on the other side. It’s also far more populated than the rest of the route so there may be dog walkers, kids on bikes wandering about, unaware they’re crossing the path of someone who hasn’t slept for two days so can barely remember their own name.

Final Word – If you’re thinking about entering do it!
