Jog to Kezar and a few warm-up loops, drills and strides.
The marathoners were doing 3x2miles, so I decided to join in for the first two then finish with some 800s. 10:27,10:34, then cruised in 2.28. Rookie and heatwave were flying around so I just let them go, making it a solo effort, and feeling okay till the last 800m where I felt my breathing a little.
Longish cooldown, and feeling happy enough with that.
