Returned to a real deal, gnarly MTB singletrack that has defeated me twice, earlier this spring. Lots of hairpin turns, roots, rocks, but mostly killer and abrupt changes in elevation that, previously, had me stalling out. Maybe it's because of all my riding over this summer, but today I completed the easier 2.2 mile loop on my Trek 29er + Stashe. Yippee! A girl can do. Not much for miles, but what a workout. (Whoa! This is getting addicting.)
