Trans Rockies Run

My little brother and his wife completed the Trans Rockies Run this month. This race is 6 days over the Rocky mountains, at high altitude, covering 200 kilometres, but does have a hot shower truck for the end of each day, which sounds amazing! He wrote up their experience, it's well worth a read, a key question they discovered was:

‘what temperature is it in a tent at 10,000 ft elevation at 3a.m. in Colorado?’
