Another treadmill run. 60 kph winds, -30 windchill, and 30 cm of fresh snow on the ground.
Did 1 mile easy, 1 mile MP, 1 mile easy, 1 mile MP, 1 mile easy, 1 mile MP, 1 mile easy. MP was between 4:15 and 4:20.
Legs felt a bit heavy, but energy level was good. HR was low during MP miles, around 143. Took about 90 seconds to recover from interval 1, 105 seconds for the 2nd and 120 seconds for the third.
