“Get over this massive mound of tires.” Best way to train: High knee sprints. Also included in your distance training. Do 100 yards of high knee sprints at a different random interval during your run. In the weight room, include hanging knee-ups. They'll get your abs and hip flexors ready for the pit (and also help you with your incline running). 3 x 15. Use a medicine ball or ankle weights if 15 reps are easy.
