At some point in training, I wear down. The hard part is figuring out what are normal aches and weariness from signs to back off. This week kinda tested me. The first part was a 14-mile run on Monday done without fully recovering from my long run. By the middle of the week, I felt crappy, but turned the corner with a great tempo run. I hit 6:30 for six miles. Then came the pain. My Achilles is sore. It's nothing terrible, but it certainly aches. I ice it as much as I can, gobble Advil and work on stretching. Yesterday, I had a great long run. The Achilles was tender at the start, then pretty much was fine, although it bothered me a bit at the end. This morning's recovery run was the same thing. I woke up pretty gimpy, started off sore, then felt alright. This is tricky. There's a reason Achilles is synonymous with "weak point." It can easily lead to tendonitis and a chronic injury. Overall, I had a great week training, but this soreness concerns me. My schedule calls for another tough week before a recovery week. I'm also aiming for an 18-mile race on Sunday that I'll run as a progression run that includes 12 miles at marathon pace. This week, I might take an extra rest day. I usually allow myself one wildcard rest day during the month. Might be a good time to use it.
