2 miles warm up, 8x30 second uphill going from 5k to 1 mile pace w/ a jog back down, and 2 mile cool down for a 5.4 mile total. Was a bit warmer around 21°F and negligible wind but it was just as dark!
The plan was for 10 repeats but on 7 and 8 I was breathing like I had asthma so I called it and started the cool down.
