The half marathon follows the High Peak Trail from Friden to Cromford over firm compacted limestone and cinder surfaces on former railway tracks making road running shoes ideal.
There is one road crossing a little over 1 mile after the start of the half marathon. After this the track descends in three stages, at about 8, 9½ and 2½ miles, the last descent being about 1-mile-long down the steep incline to the Cromford canal at High Peak Junction. At this point, the canal crossing directly ahead is ignored in favour of a right turn and heading along the canal path for a short distance until the next bridge is reached. After crossing the bridge and turning left, there's just over a mile to go along the towpath before turning right into Cromford meadows for the finish.
