JHS called T2 this morning and cancelled the bike ride, since it was pouring rain.
Instead of riding outside with T2 and JHS, T2 and I scheduled a trainer ride at T2's in the afternoon. I packed up my bike and trainer, drove over to T2's, and setup there. We had a nice 50 minute spin on our bikes, while watching Ironman Austria and ITU Honolulu coverage T2 had saved on TiVo.
T2 looked at my aero form, and noted I appeared stretched out, and that my forearms need to come back a few inches for me to get the 90 degree shoulder angle. T2's form looked great - 90 degree hip angle and shoulder angle, and T2 only has road geometry bikes! I stayed in aero form for approximately 5 minutes before sitting up a bit for the rest of the time.
I had to squirm a bit due to a bit of butt numbness... after getting fit for my bike, my next priority will be to find a comfy saddle. Something a little wider as my hip bones seem to bear most of my weight.
Overall, the spinning went well, and it did feel pretty good to get started. Moreover, T2 and I helped motivate each other to get in a workout on a rainy day, something we'll likely need to repeat.
