Met a group of girls up in Farmington for a long run. The plan was twenty with 4 tempo at the end. I struggled. I hit a 6:05, a 6:08, and then fell apart. My legs are tired. I am running 80 mpw to their 55-65 a week. I'm wondering if I'm doing too much, or if this is just all part of marathon training. It seems like such a balance. I averaged 6:25 for the last four. 7:09 average for the whole run. |
