Pulled left calf

Sat, 3/29-Went to the trail again and ran a sluggish 4M. 2 miles down in 16:40; rested to stretch calf a little; 2 miles back in 15:20. (32:00)

Fri, 3/28-Went to the trail (less preferred side) and ran a hard-fought 6.2M. 3.1 miles down in 25:30; rested some because of left calf; 3.1 miles back in 23:30. (49:00)

Thurs, 3/27-Arrived at TCNJ's track at 5:30 for a workout, despite my sore left calf. On tap today:

3x200 in 30, 29, 28 (3:00 rest/200m walk)
3x150 build-ups (first 50m in 7.5s, second 50m in 7.0, and third 50m in 6.5, for a total of 21.0)

Actuals:

200s--30-low, 29-mid, 28-high
150 build-ups--21-high, 21-mid, pulled up with 50 meters to go. Pulled left calf. Ouch.
