MTB (gravel? grinder) 5:59:54  47.74 mi (8.0 mph) +6461ft
shoes: Trek XO2
Big day tackling plenty of singletrack, hike-a-bike, mud, gravel climbs/descents in the scenic Mad River Valley. I will rethink bike choice if I do this again. We cut off the last 1000ft dirt climb "because it was getting late and we had to still drive 3 hrs home" - yep, that was why.
