Notes
Starting temp 68, DP 60; ending temp 73; DP 58. Wind of 9 MPH from north.
Parked in Rosslyn and went out and back on Custis. Was going for 6 miles at marathon effort, but shut it down at 4 as my HR wasn't quite under control and my breathing was a bit off. Felt like I was edging towards tempo effort
First four miles averaged 9:08; next 4 miles at 7:41; next 4 miles at 7:08, cooldown 3.5 at 8:36 pace.
Breakfast was rice, hemp powder, birthday cake and salted caramel GUs - sat well.
Breathing was Advair 250/50, Qvar, and two puffs rescue midway through run.
Carried water bottle but drained it.
