Route Description

The race starts from the historical grounds of Berkhamsted Castle (TBC) and finishes within Hampden Meadow in Wendover.

The Ridgeway National Trail traverses these two locations and runners join the trail from Ivinghoe Beacon, having completed an enjoyable undulating first 10K through the Ashridge Estate (National Trust).

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.

As the route heads towards Wendover there are many ancient woodlands and rolling hills to tackle.

After a pit-stop in Wendover the route continues up Coombe Hill and alongWhiteleaf Hill and looping back to complete the 50K distance.

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 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 each checkpoints will be monitored and maybe 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?

Please wear trail running shoes for this race. You will encounter varried terrain along the route that will become slippery/muddy in wet weather conditions.

What prizes are awarded at this event?

There are awards for the top three male and female finishers overall, along with age category awards for FV40, MV40, FV50, MV50, FV60, MV60, FV70, MV70.

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 via by loading the 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).
