Yesterday, I started training for my 7th half marathon which will be the St. Louis Rock and Roll Half Marathon near the end of October. I'm going to try to update this day to day, or at least week to week.
Day 1 - 4x400, track workout
Warm up - 4:30 min jog
4-400's - approx 2 min a piece with 2 minute recovery inbetween
Cool down - 4:30 min jog
Total - 22 min - 2.5 miles
I also did some high knees, butt kicks, crunches, squat jumps for about 10 min
Day 2 is CX Training for 30 minutes.
