I found a pal to do intervals with. Erich, former very successful Cat 2 racer in the 90's, now 50+ and 30 lbs. overweight, but still very fast on the flats. He hurts me on the flats a bit, I do that to him when the road tilts upward (I'm only 10 lbs overweight and dropping fast). We did 40 minutes of trading hard pulls today and both agreed that we'd never go that hard on our own. We'll start doing that a couple of times a week. That will get me into race shape.
Between that, my rapid weight loss and my Di2, you are all effed.
First race of the season Sunday AM. Rt. 29 TT. 35k (20+ miles) of individual TT suffering. I'm looking forward to it.
