training 4-23-13

Folsom Canal, 44.5 miles (3167.5 YTD). QuestXS (foothole covers, hood w/shield). N-28.6, S-33.9, N-30.1, S-34.6, N-flatted, S-34.9. I had two flats today. One was waiting for me and required a boot on the tire and the other happened during riding and was on the rim/spoke side of the tube. The stock Kojaks lasted 3228 miles before threads started showing. During those miles I had no flats. The Duranos have been on less than a week. Yesterday was very caloric-surplus and it showed in my endurance today.
