I took part in both the coed y Bernin and dyfi gravity enduro, the dyfi was superb ,great fun.
As others have said don’t underestimate the level of fitness required, I made all the start times with a few minutes to spare and was very lucky to reach the second after a puncture.
I was late arriving on the practice the day before and rode 4 out of 5 stages blind.
I held my own on the dh bits but got overtaken on the uphill portions by some very fast riders, it was a true test of overall skill and fitness.
