Last night after driving to Vegas and back my foot was pretty sore, but when I woke up this morning it felt decent. I did a simulated short tempo run on the arc trainer. The plan called for 2 mile warmup, 2 mile tempo, 2 mile cool down. I did 20 min warm up, 15 minute 90% effort, 10 min cool down. I had to stay focused for the last few minutes to keep up the cadence.
