Welcome to the Hibernal Hills 20 mile

The Hibernal Hills 20 mile is a single loop race around the beautiful hills of Hampshire and West Sussex and is a great race distance to get the year off and running.

Starting and finishing in the stunning location of Queen Elizabeth Country Park under Butser Hill, runners with follow some great countryside trails, rolling hills and a few steep climbs but on the whole, a very runnable route. The route is made up of a great mixture of trails from flat runnable sections, hills, forest tracks and countryside paths.

There is 2400 ft of elevation and as with all our races, it is fully marked for easy navigation and regular aid stations. It is a UTMB Index race and worth 1 ITRA point.

Our permits are granted through ARC. Permit Number pending.
