Getting ready for Schaeffer Farms

Last workout before saturday's race. 2 sets of 6x1 standing hill repeats with 53x11 gearing and trainer set on high tension. 26 registered so far for ss class and it is packed with the fastest guys around so I need to stick to my game plan of not having a game plan until saturday after the horn sounds. Last year I finished 4th with a time of 1:38:49 for 19 miles. My goal is to shave 8 minutes off and finish with a 1:30 in order to finish in the top 5 with these guys. Funny thing is 17 of the 26 are over 40. Must be a 40 thing. I switched full time to SS when I turned 40. Now 43, I cant imagine riding a geared bike-though I do own one-ssshhhhhhhh.
