This morning completes the first full week of training; 3 bike rides and a run. Not great but considering it is ex nihilo I'm not too terribly disappointed. Today's ride was 22 miles in 1:20. Again, not great, but I have to start somewhere. The last few miles of the ride was not easy. The supporting muscles (core mostly) had lost their strength; unpleasant and instructive. Suffering for the sake of something other than suffering is demonstrably worthwhile.
As an aside the weight loss has started slowly but evenly. Three pounds lost week. I think the increase in physical activity and removal of soda from my diet are entirely responsible.
