Last year I did the Beaumont, TX Spindletop Spin century on the fixed gear. Averaged 17 and felt pretty good finishing but it took at least a month to recover. Doing it again this coming Saturday but not only older but wiser I will do the 60 mile course. It is totally flat but, hot, extremely humid and gets windy-headwind the long stretch home. If I can get in with a good group it shouldn't be too difficult. Rode 43 with a small intermediate level group of social riders today did a lot of work and felt good. Should be more fun than last years "death ride"
