ONION VALLEY Jul 11, 2011 Categories: MASH Frames 0 Comment Just back from onion valley. it was a hot one —95 degrees in the desert heat. the climb was a perfect warm-up for the cols agnel, galibier, and d’izoard; and l’alpe d’huez. onion valley has an average of 7.6% in its 21km, with a 1587m gain. speeds of up to 96 kph are easy on this out and back monster outside of independence, ca.
