The Centurion Track 100 is an elite level event, designed for runners to compete under the fastest possible conditions and with a focus on record setting. The main focus is on the 100 mile distance, but official record ratifiable splits are also taken at 50km, 50 mile, 100km, 6hr and 12hrs on route.

The 100 mile Event is certified Gold Label through the IAU, with the 12hr mak also Gold Label. The other four official splits/ distances all hold a silver label.

At the 2021 event, Aleksandr Sorokin the World 24hr Champion, set new 100 mile and 12 hour World Records. Samantha Amend broke the long standing British 100 mile record. And a total of 14 National and World Best marks were set for both 100 miles and some of the shorter splits.

The 100 mile distance final cut off is 17 hours.

This race follows in the footsteps of some of the classic events seen during the 1970s and 1980s when many of the fastest British 100 mile times were set. A full list of the All Time top British 100 mile performances for both men and women can be found via the stats page here.

The course will be officially measured and certified under UKA standards, be overseen by a UKA referee, a UKA Level 4 time keeper and holds a UKA permit.

Anti-Doping will be in place for any World or Continental Open Records.

General Info

The race takes place on the track at Bedford International Athletics Stadium. This is a, for now, temporary move away from the Julie Rose Stadium, who are closing for Spring 2022 to resurface their track. Runners will begin at 0600 on Saturday 23rd April 2021 and the total cut off for all runners will be 17 hours or 2300.

Runners will run in Lane 1,2 and 3 with race official check point and any crews to be set up in Lanes 4-8.

Runners are permitted and encouraged to bring a crew, each crew will be able to set up in Lanes 4-8 and tend to their runners as often as they wish but crews must remain completely stationary when handing anything to or communicating with a runner. 


This event is by invitation or qualification only - see below.

Entry is limited to 25 runners total in anticipation of 20 starters. The field is set small to create conditions for the optimal distance travelled for all runners. 

Entries are first come first served and any application will be accepted or refused within a week of our receiving it.


Runners meeting one of the listed qualifying standards may apply for acceptance into the race. The entry fee applies to all runners, regardless of qualification time.

Runners not meeting the explicit listed times may petition for acceptance via other performances (eg course difficulty) and these will be judged on an individual basis. We will prioritise those who have run ratified qualifiers or fast times for distances in line with the specificity of this event.

Qualifying marks should be recent, preferably in the last three years.

The course is a 400 metre all weather track at Bedford International Athletics Stadium. Runners will change direction every 4 hours, with the final change occuring at 12 hours elapsed - for the last 5 hours only (cut off 17 hours).


Electronic Timing at the start finish line.

Manual lap counters for every runner.

Overseen by UKA timing officials ensuring all splits are record eligible under UKA/ IAU and World Athletics rules.


Weather in the UK can be variable at the best of times but we have picked late April, as offering optimum potential for dry and moderate temperatures, with long daylight hours. Runners should prepare for all conditions on the day. The track is well shielded from the wind by a very large grand stand down one side, and is protected by banking on the near bend. 


Runners will each be permitted their own designated crew area including shelter, chairs and tables from which they may be tended to. 


There will be a full aid station providing an extensive range of food and drinks to all runners for the duration of the event. Crews will also be able to access both fluids and food for their runners. 


All runners will have their 100 mile split recorded. Runners stopping before 100 miles will be recorded as DNFs due to the fact that this is a distance race and not a timed event.

Splits will be taken at the following marks: 50km, 50 mile, 100km, 100 mile, 6 hour, 12 hour.


Awards will be presented to 1st overall in the mens and womens events. There will be no Age Group Awards.


Whilst the core race is the 100 mile distance, splits will be taken at 50km, 50 miles, 6 hours, 100km and 12 hours. All of those split distances are individually ratified as record eligible. Labels are held as follows through the IAU for each distance:

100 Mile - Gold Label
12 Hour - Gold Label
100km - Silver Label
50 mile - Silver Label
6hr - Silver Label
50km - Silver Label
