Took a long warmup today. Over 30 minutes of easy jogging. Danny and I then ran 1000 meter loops with the first 400 fast and relaxed, and then jog-walked to the start-finish and did it again 4 x.
Nothing startling. 1:44-1:41-1:41-1:42.
Slow but age graded to 73-75 seconds when I was young and fast. The goal was not to go hard but to get fast leg turnover and some faster than threshold type speed.
