Never sure on how to split fast vs slow miles. Somedays a 7:30 seems fast and somedays it seems slow. For purposes of this posting, I will say anything under a 6:52 pace is fast, since that turns out to be a 1:30 half marathon pace, or very close to it. And that was also my average speed. Ran 12 in the AM on the JRT. It was a great morning to run. A little snow, a few slick spots, great temperature. Headed south on the Jordan River trail, after a 1 mile warm up at 7:46, I decided to try to push the pace a bit, here and there. 1 7:46 150 bpm 2 6:31 159 bpm 3. 6:44 151 bpm 4. 7:19 134 bpm 5. 6:56 143 bpm 6. 7:19 144 bpm 7. 6:49 143 bpm 8. 6:05 164 bpm 9. 6:49 150 bpm 10. 6:52 155 bpm 11. 6:34 151 bpm 12. 6:35 161 bpm Ran 8 at lunch in Lindon. Ran first 5 or so miles with Wes. Headed out on our old Walmart run, and when I figured I was out far enough to be at 8 when I got back, I picked up the pace for the last two miles. 6:44, 6:24. I must say, putting down a 6:24 for mile 20 for the day is not too shabby. And still feeling good. I could have run more. Garmin says I burned 2900 calories in the 2:25 I ran today. 13. 8:32 128 bpm 14. 8:49 127 bpm 15. 8:45 124 bpm 16. 8:04 122 bpm 17. 8:06 122 bpm 18. 7:50 129 bpm 19. 6:43 147 bpm 20. 6:23 164 bpm
