Set in the heart of the Chiltern Hills our single loop course takes runners on a stunning journey along The Ridgeway, Chiltern Way and Ashridge Estate.

This is a varied ultra marathon that combines forest running, ridgeline views and plenty of picturesque countryside villages and footpaths.

With an elevation gain of ~835 this is a challenging but runnable ultra.
