Course and format
The route is an out-and-back from the Taproom along the Griffin Trail and Brampton Valley Way. The lap length is 3.3 miles. Surface is mostly crushed stone; a recently resurfaced section is noted and there is one grass section of about 100 m. The course is relatively flat with gentle climbs, runs between arable farm fields and is largely exposed rather than under tree cover. Entrants complete as many laps as they wish within a six-hour time limit.
- Half marathon: 4 laps
- Marathon: 8 laps
A GPX file for the route is available. The Taproom location will be used for the first time for this course; the organiser has run 100+ similar events at other venues.
