next up: 50K

I'll be running the 50K version of Patrick's 100K ultra on Aug. 2nd. I plan to run it, by heart rate, as a practice marathon prior to the Twin Cites marathon 10 weeks from now. I believe my max HR is 182 and my AT is 167/168. I plan to run the first 13 miles at a heart rate of 154, the next 7 at 157, and the next 6 at 160. I'll back off a bit for the final 5 miles. It's a loop course so I'll get lap splits every 5K. It will be interesting to me how my pace is per loop per HR. I'll know on the 2nd but I'm hoping to average an 8:00 pace. The major factors out of my control will be heat and humidity.
