Common questions

: The Windsor 50 offers 3 distances: 50km (31.1 miles), 25km (15.5 miles), 10K (6.2 miles).
: No course file for the Windsor 50 yet, so there's no measured climb here. When Ultra Challenge 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 Windsor 50 yet.
: Yes, the course is marked. Navigation skills are not required.
: We don't hold a compulsory kit list for the Windsor 50. Ultra Challenge confirm mandatory kit in their race information, usually in the final instructions.
: We don't hold published time limits for the Windsor 50. If Ultra Challenge set cut-offs, they'll be in the race information.
: We don't hold a checkpoint list for the Windsor 50. What's on the table varies a lot between races, so check the Ultra Challenge race information rather than turning up expecting food.
: Not yet — we don't hold a course file for the Windsor 50. Some organisers only send the GPX to entrants. If we get one, it goes up free, with no sign-up.
