Fartleks on the Trail

Today we did a new fartlek workout on the trail. We started at RunTex and went counter clockwise on the trail. Once we crossed I-35 we started out. The plan was 3 minutes fast, 1 slow, 2 fast, 1 slow, and finally 1 fast. We did 3 sets. My calf is still a little sore, but I stayed close to the group for all 3 sets. We did some strides when we finished and called it a day.
