Starting temp 68, DP 65; ending temp 69, DP 66. Wind of 3 mph from NW.
Parked at Long Bridge and ran to MV trail. First took trail down to just north of Alexandria, and then back up to right before the boards near Teddy Roosevelt Island. Did a fartlek of 9x 4minutes on, 3 minutes off, after I passed the airport exit. (Kept the on pretty relaxed)
L/R balance at 48.8/51.2
Breakfast was rice, sunflower butter, Leucine powder, and berry and Smores GUs - sat well.
Breathing was Advair 250/50, Qvar, and 2 puffs of rescue. Breathing fine. Felt much better than last week.
Took half an espresso GU just before starting the fartlek. Also carried water.
