The race course for 2017 will be the same as for the Spring Trails event in the past few years, utilising well maintained forest trails. The officially-measured half-marathon course (13 miles 192.5 yards) is run on way-marked trails laid out by the Forestry Commission. Special permission has been given to stage the race over this course.

The course begins at Speech House and then follows the trails in a clockwise direction through the Forest of Dean to return to the finish at Speech House. The multi-terrain route will be fully signed and marshalled, and marked by yellow paint on the ground. Mile-markers are provided. The route generally uses well-maintained tracks with gentle inclines.

The race will be led by lead cyclists. Roads will be closed to allow runners to cross freely. There are three water stations at approximately 5 km intervals, and drinks will be available at the finish. The race starts at 10am.
