I think I really let my self go, relatively speaking, during the cyclocross season. I was trying to mix it up with the Cat 3s in the B races, but I never came away with great results. The training was really slack at that point. After that, I rested for a couple weeks, then got serious again.
Playing with the new (used) PowerTap has been fun. I ride so much on the trainer, that in the past I was able to gage my output level by the speed on the computer. To do this, mount the sensor on the back wheel. It helps to look up the power curve for your particular trainer.
My most significant accomplishments for this training block have been: 1) Creatively modifying my schedule - I got sick Tuesday the week of the city of lakes loppet, then, instead of powering through a hard week, I decided to make it a rest week and get recharged for that race. The following week (ending tomorrow) was then to be a quasi-rest, quasi-on week. I feel great for the nice result at the COLL and for my good trainer ride today. 2) Squatted 255 lb. 8 reps, 6 sets, with lots left in the tank. This is a big improvement over last year in terms of reps. 3) Hitting my workout time goals without dorking up my personal life. 4) Had a great 5 min. time trial today according to the benchmarks in the Coogan/Hunter book.
We'll see how things shake out as I enter the base 2 period as defined by Friel. Here's some good reading for the self coached mountain biker:
