Route Description

From our event base, runners follow the Chiltern Way towards Lilley and out to Warden and Barton Hills.

After leaving CP1, the first big climb awaits, but once successfully navigated, a lovely undulating section to CP2 awaits.

Out of CP2 runners explore Pegsdon Hills and along to Offley.

The last 12k to the finish is a mini rollercoaster with three small hills to get up and down.

Overall the terrain keeps the running varied and doesn't ever feel like your doing too much of one thing. We are fascinated to see what the course record will be!
