XNRG 2021 events now open for booking!

Due to ongoing COVID restrictions, our usual Amersham 50km race is unable to go ahead this year.

So that your training is not in vain, you can still claim your Amersham medal by completing a 50km run, walk, or hike over the weekend of the 6th and 7th of March.

To feature on the leaderboard and be eligible for awards and prizes, complete 50km in a single run or walk.

Latest results

Everyone who takes part will receive a medal. There will be prizes for the fastest male and female as well as special spot prizes from our sponsors.






This event is free of charge to enter but we hope you will consider making a donation to support the work of Humanity Direct who have missed out on a significant source of funding due to the cancellation of the real-world race.

If you'd prefer to fundraise for the charity, you can register on their fundraising page.


You may have an entry voucher in your account if you have deferred from a previous event.

The system will, by default, use this voucher to discount the event fee.

As the event is free, you may not want this!  In which case, click on the voucher to deselect it.

To log your 50km

If you have Strava (you can create a Strava account for free), connect your account to UltraBritain (log in to UltraBritain first) by clicking on the orange 'Connect With Strava' button to the right/below and we'll collect your activities automatically.

If you do not have Strava, upload your results manually. Log into your Ultra Britain entry form. Select entry / tickets and you will see a blue button called ‘Your Activities’ where you can log your distance and time.

Note - If you complete a run/walk longer than 50km, we'll calculate your virtual 50km time based on your average pace per kilometre during that run.
