Met the Brooklyn Tri-Club for the Tuesday morning bike workout. Took my road bike rather than my tri-bike for a bunch of reasons: (1) tri-bike has a flat; (2) didn't feel like fixing the flat; (3) have a slight concern that the tri-saddle has been aggravating my hamstring/glute issues; (4) really didn't feel like fixing the flat. Anyway, I always forget how great it feels to ride a bike that fits properly. Spin bikes never do. Also, the need to balance evens out the pedal stroke and everything else. I did about 30 or so miles in Prospect Park, not too fast in a big friendly group. I was on the bike for two hours, and finished feeling great. Heel is looser, hips are looser, hamstring is less sore, adductor is less sore.
I usually think of biking and spinning as pretty direct substitutes, but now I'm not so sure.
