Facilities are made available for the runners to take their own food and/or drinks from the start to these stations.
The race was first run in 1998 on a slightly longer course (54.918 km, 34 miles 219 yards) which involved the final section from Two Bridges to Princetown going past Dartmoor Prison instead of on the direct route.
Since 2002, the race has been run on the current, slightly shorter route (the only exception being in 2018 as noted above).
The race begins in the centre of Princetown (Ordnance Survey mapping six-figure grid reference SX591735 at an altitude of 420 metres) and goes along the B3212 to Two Bridges (SX608750 340m).
The road now rises steeply onto YarTor Down (355m) before falling again, passing Poundsgate, until it reaches New Bridge (SX712708 100m).
The road travels north passed Rowden Cross and Longworthy before the runners turn left (SX697778 315m).
