Hill sprints at Sugarhouse Park. I ran to the park at a normal easy pace (7:30 or so), then did 8 sprints up the sledding hill, jogging a serpentine route back between each. I started each sprint near the creek on the flat section and finished at the top of the hill. It hurt. My legs seemed to give out before my heart did, because my heart rate only went above 180 once, and that was on the first or second sprint. After that, even though I felt like I was dying near the top of the hill, my heart rate was only hitting 176-77.
I ran home as my cooldown, but I stopped and walked about half a mile at about 6.5 due to GI issues. |
