Ran 3 easy miles, then 3 mile progression, then 3 more easy. Didn't want to kill myself on the 3 fast miles but wanted them faster than marathon pace. So decided to try and keep them under 7 min pace. Run was OK, I felt good but not great.
Miles 4, 5, 6 ave pace/HR: 6:56/170, 6:46/180, 6:38/186.
Overall AP/HR: 7:45/160.
Hudson on steep hill sprints: "These short, maximal-intensity efforts against gravity offer two key benefits: First, they strengthen all of the running muscles, making the runner much less injury-prone. They also increase the power and efficiency of the stride, enabling the runner to cover more ground with each stride with less energy in race circumstances." |
