Route Description
The race starts from Berkhamsted Cricket Club with a segment through Berkhamsted Common and along to National Trust's Ashridge Estate.
Runners join The Ridgeway National Trail and follow it along the stunning section through to Aldbury (CP1).
From Aldbury the journey along The Ridgeway continues for another 13KM to Wendover (CP2).
Wendover is the furthest point out and here runners turn and begin to follow the Chiltern Way on a more intricate set of paths featuring much more single track and woodland running.
The loop winds its way back into Ashridge and finishes with a nice downhill approach back into Berkhamsted.

Event FAQs
We've answered some common questions below. Please contact us if you have any further queries.
How difficult is this race?
The Chiltern Ridge Winter 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 hike/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.
We ask runners to make sure they have access to the route via a phone or watch, to act as a backup in an emergency.
What are the cut-off times for this race?
There is an overall 9-hour time limit for this race. Anyone running significantly behind this time at checkpoints will be monitored and may be advised to stop for safety reasons.

Most GPS watches allow you to upload a GPX file of the route for you to follow whilst running. Typically this is done by loading the route 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.
