Notes
6 x 800m (400m jog and a sip of water). Paces increased with each interval, averaging 2:53.7, which is maybe 5:48-9 pace per mile. Felt strong and started finding my form about midway through: started using my arms, taking shorter steps, and standing up tall. Much better than last time. But I shouldn't do this too often, because it's hard on my body and must require a while for recovery. Once per week at most. Once every two weeks would be fine.
