Route Description

Our half marathon route begins at the National Trust centre within Dunstable Downs.

The first quarter of the race takes runners out to the Tree Cathedral, Bison Hill and back past the centre.

Runners then complete a full loop of Kensworth Quarry, passing our aid station at 10KM.

Upon rejoining the Downs the runners complete an out and back to Five Knoles and then back onto the lower Downs trails to run what was the first 5km, now in reverse.
