Thanks Werdna. So was the Wroxall rounf 1500ft or 2000ft? I've jusst checked my Suunto and it measured a 594m ascent which is 1948 feet. No GPS on the watch but I re-set it at sea level and the air pressure didn't change that much. I feel even better now! First run today since the race actually; was feeling shattered after it so gave my body a chance to recover with tons of grub, walking and stretching. Were you wearing Running Bear socks Werdna?
