The trail from Ivinghoe to Aldbury is arguably the best 5K of the entire Ridgeway (135K long!) and will treat runners to some brilliant views.

How difficult is this race?
The Chiltern Ridge 50K is considered to be a challenging run on undulating/hilly terrain. That being said, during previous editions of the race we have seen many runners complete this as their first ultra, well within the cutoff time.
Overall drop-out rates are very low and providing you adopt an intelligent strategy, such as a walk/run approach, we are confident all runners can complete this course within the 9-hour cutoff time.
Do I need to qualifiy?
No, there are no qualifiying standards required to enter this race.
I'm worried about getting lost?
Our route will be marked throughout with orange signage/ribbons, along with marshals at several key points. Course checkers will be out during the race ensuring that signage remains in place.

Most GPS watches allow you to upload a GPX file of the route for you to follow whilst running. Typically this is done via by loading the GPX file into the app (i.e Garmin Connect), and then syncing your phone/watch together.

It was so well organised both in the weeks building up to it and on the day, and the course was so well marked you couldn’t possibly go wrong out there.
