A clean chain and chain ring for smooth shifting for the Mountains of Misery ride: http://www.cyclingdoubleheader.com/MoM.html
103 miles, 10,000 feet of climbing and a 3 mile climb at the end 11.9% average grade. Only the last three miles were really hard. But I was tired by mile 93. I finished in 8 hours, 31 minutes. The first one finished (not a race) finshed in 5:15.
