It is tough, 13 miles straight up with no flat spots to rest.
I finished the 75 in a little over 6 hours, folks who came down for the first time in a somewhat longer time and another friend who did the century in about 7 hours, which is pretty amazing for a first timer.
Robbie, sadly, had a difficult day. Did not see or hear from Seypat today.
