Common questions

: The Gatliff Marathon offers 2 distances: 50K (31.1 miles), 25K (15.5 miles).
: No course file for the Gatliff Marathon yet, so there's no measured climb here. When COPSE publish one, this fills in.
: Not graded yet. A TRP grade is worked out from distance and climb measured off the course file, and there isn't one for the Gatliff Marathon yet.
: No. The Gatliff Marathon is not a marked course. You are expected to navigate it yourself.
: We don't hold a compulsory kit list for the Gatliff Marathon. COPSE confirm mandatory kit in their race information, usually in the final instructions.
: Overall time limits — 50K: 10h, 25K: 10h. 10 hours; all to finish by 18:30.
: We don't hold a checkpoint list for the Gatliff Marathon. What's on the table varies a lot between races, so check the COPSE race information rather than turning up expecting food.
: Not yet — we don't hold a course file for the Gatliff Marathon. Some organisers only send the GPX to entrants. If we get one, it goes up free, with no sign-up.
