This comes up periodically. No one could verify the 37 minutes on the current course, lots of people knew someone who’s friend did a 37, and it was thought to have been done when the trail was very new and rather different.
They held a student champs race there in 2008, the fastest lap (by a top 10 Elite racer) was 44 minutes IIRC, I don’t think anyone could still go sub-40 except the likes of Niño Schurter, Absalon etc.
My PB, from the race, was 47 minutes I think, may have been slightly slower. Fairly dry, S-Works Epic.
