Hey, guys. A couple of you asked about how my last long run went on Sunday. It didn't. I got up, ate a bagel, and started my run at 8:45. It was already warm, sunny, and humid. I felt OK the first few miles, but my legs got progressively heavier and heavier. By the time I hit the 8-mile mark, I had nothing left, and there was no way in hell I could imagine running another 12 miles. I ran another 3 miles (interspersed with a few walk breaks) before calling it a day and walking the last few miles home. I kinda knew it was just a function of the heat/humidity and not being adequately recovered from Friday night's tempo run, but I was embarrassed anyway that I'd quit, so I dedided not to say anything.Fast forward to tonight, 20 degrees cooler and a couple of days later. With less than 3 weeks to go to my goal marathon, I contemplated just saying to hell with the 20 and going ahead with my taper, but I really wanted to do that one last long run, so after having run just an easy 5 last night, I decided to attempt the do-over. Purposely started out nice and easy and held myself to an 8:15 average (1:22 total) for the first 10 miles. For the last ten, didn't even look at the watch and just focused on a good, comfortably hard effort. Averaged 7:33 on the back half (1:15) for a big 7-minute negative split. My last mile (7:07) was my fastest, and I was running sub-7 pace when I finished. One of my most satisfying 20-milers in a long time.In retrospect, I definitely made the right decision bagging the run on Sunday, as my body clearly was telling me that it needed more than 36 hours to recover from that tempo run. I'm also very glad I did the do-over tonight. One last big confidence boost going into the taper.
