Xc (Interval workout) 1 
Biked to the lake for a warmup. When I arrived I ran for another 5 minutes before going right into the workout.
The workout was 4x 15 min. 30s @ tempo, 2 30 easy, 30s @ tempo, 2 30 easy... I ran the majority of this workout alone but did a couple intervals with Derek, Gavin, and Zimmack.
My breathing and leg fatigue was a limiting factor.
Following the workout I did 15 mins of cool down. Hip mobility, strength exercises, and recovery.
