Stupid Garmin altimeter smoothing algorithm screwed me out of 2000+ feet of climbing on this one. Loading track into Topo shows comparison of smoothed GPS data with actual digital elevation map. Numerous 20-40ft climbs don't even show in Garmin data, but my legs and lungs sure as hell knew they were there. I'm going with Topo's roll-up for climbing on this one: 8787ft.
Probably longest unsupported ride ever. Ran out of food with 2+ hours riding to go. Massive HAB with 30% grades. Had some company at high point of ride when dude from SoCal was doing similar route with similar death slog hike-a-bikes.
