I know everybody is still going to call this "ultra fast," but I swear its not! The difference? Heart rate. On my previous tempo runs my heart rate would be 180-185 bpm; indicating I'm past my lactic threshold. Today, however, I kept my heart rate lower, 170-175 bpm. As a result, I still felt surprisingly fresh at the end, as opposed to wanting to keel over!
Call that my disclaimer. Call these the numbers:
7:37 (152 bpm, warmup)
6:43 (170 bpm, lets rock!)
6:28 (173 bpm)
6:23 (170 bpm)
6:11 (174 bpm)
6:58 (170 bpm, cooldown... sort of)
'Honest' HR: 172 bpm
'Honest' pace: 6:26/mile
Things I noticed:
- Perfect negative splits. Every mile got faster. Right on!
- Very similar to my tempo run a few weeks ago, but I didn't have to work as hard!
- Running fast is fun!
- I always get 'velocitized' on quick runs, unless I go 100% all out. Its like getting off the express way and accidentally speeding through town. I tend to do that on cool downs. And when I get off the express way.
