Centurion Running from a finisher's side: SDW100 and Winter Downs 200
Centurion Running organises some of the best-known trail ultras in the UK, including 100-mile races on the South Downs Way, North Downs Way, Thames Path and Chiltern Wonderland routes, and the Winter Downs 200. In 2024 I finished two of them. This page is a runner's view of what those races asked of me and what a first-time entrant might want to think about.
To be clear from the start: I have no affiliation with Centurion Running. For current entry rules, kit lists, cut-offs, crew and pacer policies, read the organiser's own website for your edition. Rules change.

What makes a Centurion race feel different
Live tracking and checkpoints
Both of my races were tracked live, and the public results show each runner's times at checkpoints. That is useful for crews and family, and afterwards it gives you an honest record. My SDW100 tracker, for example, shows me through Queen Elizabeth Country Park at 10:28:29 on the first morning, Washington at 17:50:44 and Housedean at 23:22:45, before finishing in the early hours of 9 June. Clock times like these are not splits you should copy; they reflect one runner on one day.
Time limits
A 100-mile race with an overnight section and cut-offs rewards steady progress more than speed. The finishing time on the results page is total elapsed time, including every checkpoint stop.
Crew, or no crew
My Winter Downs 200 was crew-supported, with planned meeting points, kit changes, timing and fuelling decisions, and some filming. Whether and where crew are allowed is set by the organiser for each race; check before you plan anything around it.
Choosing your first Centurion race
I came to SDW100 with 30-plus marathons and several ultras behind me. Here is how I would think about it now.
- Start below 100 if you can. A 50km or 50-mile event teaches you fuelling and walking without a night section.
- Read the course. The South Downs Way is mostly chalk and grass trail with long climbs. Winter conditions add mud, darkness and cold.
- Plan for the night. Head torches, warm layers and a strategy for staying awake matter as much as fitness.
- Do the admin early. Qualifying requirements, mandatory kit and medical or registration steps are on the organiser's site.
What I learned across the two races
- Coaching earlier would have helped. I said as much on the Running Tales podcast in October 2024; my build to SDW100 is in training for my first 100-mile ultra.
- Power-hiking is a skill. On both courses, efficient walking uphill saved energy.
- Kit choices need testing. I ran SDW100 in road shoes; that is not a recommendation.
- A 200 is a logistics project. Over nearly three days, sleep, crew timing and fuelling become the race.
How 100 and 200 compare
It is tempting to say the 200 took three times as long for twice the distance, and leave it there. That misses the point. A 200-mile race includes multiple nights and decisions about rest that a 100 does not. The two results tell you that I finished both; they do not tell you that one pace was "better" than another.
