Was supposed to be 46 miles 6817' climbing, but after doing what I thought was half miles, I got in car. (Back and knee were talking to me, but I feel like I just wimped out) Got a ride to top and rode down. Top was 11,998', windy, cloudy and cold. I started down (with Diego) after waiting for others to come up, but we stopped in a shack selling aguapenela (hot sugarcane tea) and sat by the wood burning stove out of the wind and warmed up. At the start of that descent it was 50 deg. I thought i could get below the clouds and warm up but saw the temp dip to 46 degrees before it got back to 50 deg at 9000'. I had my rain jacket, long sleeve jersey underneath, but it was damp from the climb, and only shorts on. I was cold. Eventually we stopped for lunch about 10 miles from finish, then a harrowing ride back to the hotel in Manizales. I had to push up some 17% grades (on paved streets) to get back to the hotel. Glad it was the last day. Metrics show actual miles ridden and actual feet climbed (straight line is distance in car to the top - not ridden)
