: 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 Spring Trail Series yet.
: We haven't confirmed the marking on the Spring Trail Series with Ultra X. Check their race information before you enter rather than assuming it either way.
: We don't hold a compulsory kit list for the Spring Trail Series. Ultra X confirm mandatory kit in their race information, usually in the final instructions.
: We don't hold published time limits for the Spring Trail Series. If Ultra X set cut-offs, they'll be in the race information.
: We don't hold a checkpoint list for the Spring Trail Series. What's on the table varies a lot between races, so check the Ultra X race information rather than turning up expecting food.
: Not yet — we don't hold a course file for the Spring Trail Series. Some organisers only send the GPX to entrants. If we get one, it goes up free, with no sign-up.
