I've been looking forward to posting this since I started following this group for the best part of a year, as this group has been a source of inspiration for me seeing so many people provide advice and achieve their goals. I hope what follows helps others.
Today, 18th October, was Abingdon Marathon (S.England, UK).
I gave myself a New Year target to run a marathon in the year, and came into 2026 with a sketchy background of running. Mostly Parkuns in 2025, mixed up with infrequent longer runs up to half-marathon pace. I foolishly thought, with that background I could compete in a Spring Marathon with 16 weeks of training so followed a typical training plan that peaked at ~30km in April. But hell, that broke me .. and I thought there was no way I was ready for a full Marathon. Saw that Abingdon (a local Autumn marathon) was available and reserved a space for October 18th, an Autumn target made more sense.
So, after a further couple of months of base training, I picked up a new Marathon training Plan from June'26 which gave me a new plan over 20 weeks to prepare. I used Gemini AI - entered my details, target pace, background, ParkRun on Saturday, Long Run on Sunday, and a couple of runs during the working week - and it came up with a nice plan tailored to my week and target paces. Typically, I would keep my ParkRun as my tempo run (25min target), two runs in the week (Tuesd/Thurs) and a longer run on Sunday.
As things turned out, training wasn't perfect. I hit a few injuries (Calf strains), family holidays in September (meaning I missed my target Sunday long runs), and then thought I had a catastrophic injury on September 27th when I had a Grade 1 Hamstring Tear just 10km into my final long slow run. That injury gave me 3 weeks to recover, but entering taper thought it was just about possible.
Over the last 3 weeks I focused on strength training on my hamstring, and was able to return to a few short runs in the week leading to the race, but no more than 5km at target pace (5:40/km). Up until the race I had no idea whether I would be able to run 5km or 42km, or anywhere in between.
Fortunately, Abingdon Marathon is a flat race so risk of hamstring strain is reduced a bit. Weather was pretty close to ideal with temperatures around 12C, although Northerly wind picked up with wind in range of 10-16mph leading to a headwind in final few miles. The route weaved in and out of a few towns in a largely rural location, with part that contained a loop that you ran round twice. Marshalling was superb, crowds were cheering on using your name on your bib .. which really gave a nice boost and made it feel quite personal
I set my Polar watch with race pace of distance of 42.5km (allowing for distance errors) and target time of 3:59:00 to give myself a minute margin under a 4hour target. Bone-conduction earphones are a must, disqualification is threatened if ear-buds are used as parts of the route are open to traffic and marshals need to be heard to give instruction. In truth, the traffic was never a problem - the occasional cars that were passed where all considerate and the runners came first. Muse radio channel was my go to music list, which I only used when the crowd thinned out on occasions, most of the time it was nice to hear the crowd cheering you on.
For energy, I planned to use Decathlon +3hr Energy Gels that have 2:1 glucose/fructose (30g carb, 180mg salt) every 4km, so 10 gels carried in running belt with my phone. I also made up a sports drink (250ml, Active Root, 40g carbs, 567mg salt) in a soft hand-carried water bottle. I ended up taking 9 gels, one left unused, I think I missed a gel around 36km mark, in total that's about 340g of carbs and more than enough salt.
Water stations were every ~3miles and a managed to take a few gulps of water at each, and a couple of water stations provided isotonic drinks which I used to refill my 250ml. I tried to take my gels before each water station.
The start was in cracking weather. An earlier rain shower had passed, morning temperature was fresh, probably around 10C, and heart-rate was low after race started, just 124bpm in the first km, and took 5 km to reach 150 which is where I expected to be for most of the race. Those first comfortable 5km's gave me a 2 minute cushion ahead of my target time.
I checked in on myself regularly .. how was I feeling, could I keep up the pace, hamstring check, heartbeat .. and at half-marathon I was feeling quite strong.
When I hit 30km I feared the wall, but other than increasing fatigue it didn't really hit me and I mentally convinced myself it was just another 10km to go, just 2 park-runs at an easy pace.
I kept the focus on small distance targets, next water-stations, fueling, and avoiding over-stretching that hamstring. Heart rate increased to mid 150's by 10km, to low/mid 160's from about 30km. With about 5km to go, I felt my 2 min cushion was enough to ensure I could complete within 4 hours so slowed a little to ensure I didn't injure my hamstring, but was fairly confident I was going to complete. By this time, I was overtaking others who were walking or holding their own hamstrings and tried to give support where I could. The finish is a lap of running circuit at Tilsley Park in Abingdon leading to the finishing line opposite a grandstand.
My Polar Flow tracking had landed on a Training Index of 51 before the race, with a predicted time of 3:57:00. From the beginning of Feb to race date in Oct I did 141 runs, a total distance of 1540km (also cycled about 1300km from a daily easy work commute of about 13km day). For the last couple of months I'd also been using Runalyse which I wish I'd discovered earlier, and that had estimated I could also do a 3:57:00 based on my training up to the end of August and before my lack of training and injury in September kicked in which led to it predicting a slower outcome of around 4:10:00 due to the lack of long runs and distance training.
And that was it.
Rather chuffed with myself as I've dreamt of doing a marathon for decades and have been in awe of those that finish London and other marathons that I've seen on TV. And at the not-so-young age of 57 I finished with an official time of 3:56:27 - pretty much spot on with Polar and Runalyse predictions, feeling quite emotional with myself at the end.
Hope you too meet your dreams and targets and good luck with your training.
