Here's the kitchen window. Frosted up even before we started dinner.
Here's me after about 20 minutes of shoveling the driveway and sidewalk. A 30 minute run would probably have me carrying a pound of ice on my face. No thanks. Yes, my face was beginning to go red. A minute of handling a metal key ring outside had my fingers going numb. Running outside is a stupid idea, even though I'm wanting to run. Yes, that hat is warm. Just warm enough.
Instead I got on my bike for a short intense workout. Warmed up. 5 minutes on, 3 minutes easy, increasing the brake in between each set, which drives up the watts by about 10 or 15 w at the same cadence. The 4th one was getting towards the retaste zone so I backed off. Cooled down I guess I didn't wait long enough after dinner.
I'm seeing strong improvement in how long I can stay at less than peak effort, but the curve drops pretty dramatically, as illustrated in this fancy high tech graph. (I can just see DC Rainmaker covering his face with his hands.)
