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.
