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 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 8.5-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.
How do I get back to my car?
We recommend using our coach transfer to the start, or back to Berkhamsted after the race, see the top of this page for more details.
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.
Where can toilets be found at this event?
There will be temporary toilets at the event base. The majority of these will be unisex, however we will have some female-only portaloos that have sanitary products available.
Are there changing facilities available?
Yes, there will be pop-up changing tents at the finish base for runners to use.
How can I attend this event without a car?
Berkhamsted and Wendover both have train stations very close to the event start and finish locations.
What footwear should I wear at this race?

How do I follow the route using my phone or watch?
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.
If you don't have a GPS watch we would recommend using OS Maps (£20/year) or Strava Premium (£48/year).

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.
