The swim this morning was pretty good. I decided to break out of the 1:15 start mould.
250 m 4:40 warmup
20 x 50 m in 50 seconds on 1:10 start
250 m cooldown 4:50
1.5 k 33 min.
10 min core in dive tank.
Once I figured out how to keep track of a 1:10 start, things went well.
The run this evening didn't go as well. The idea was to warm up and run 5K as a benchmark to measure future progress. The warmup and first 2 K were just fine. Part way through the 3rd K, my left calf seized up. Not the cramp like I've had before. This was a bit lower down in the muscle, and was sore all over.
First K was 6:47 with average hr of 127
Second was 6:39 with average hr of 132
Third was 4:20 for as much as I did, average hr of 131.
I am beginning to think I actually have damaged it somehow. The muscle is fine for a while, but it always seems to be the first thing to give up.
