Temp and DP 58, wind of 9mph from SW; pollen of 9.2
Went for a 4 mile tempo, working with/trailing David K. Felt OK for first miles, then started running out of gas. When I started struggling, I just pulled the plug - no point in digging a hole right now. Annoyed, because I hate dropping out of workouts, but it was the right decision.
As for why I felt crappy? Probably a combo of the humidity, the pollen, still recovering from Broad Street, and reacting to Wednesday's allergy shots. Or maybe it was just a bad day.
Breakfast was rice, hemp powder, smores and birthday cake GUs, berry stroopwafel, and some water melon sport beans. Sat well.
Breathing was Advair 250/50, and Qvar, plus one puff of rescue. Breathng was OK - maybe a bit of VCD.
