Running week 2, fast intervals

6x [1m on, 1m off] run
fast pace (~6:40/mi)

Trying to get up and maintain a steady running regimen. Was going to do 8x1m today but exercise-induced bronchoconstriction started kicking in around the 5th interval. Felt good to get the motor up and running though. My speed wasn't quite as variable as the graph makes it look, I think the GPS signals are more variable coming from under something (Williamsburg bridge, elevated FDR, etc.).
