I had a run this morning that took me back to my horrible marathon run in 2007. (Isn't horrible and marathon run an oxymoron?)
Felt good the first three miles and was running a sub 8-minute mile at the beginning of mile 4 and my heart rate was still under 80 percent max. But by the end of mile 4, my shoulders started burning like I couldn't get rid of the lactic acid build-up and I could n0t catch my breath.
By mile 5 I was gasping for air and stopped to get water. I was spent by mile 6 and I'm embarrassed to say it took me 11 minutes to finish. I started feeling a little better around mile 7, oddly. But I decided to stop at 7.5 miles.
It took me about 1 hour and 10 minutes, a pace of 9:20 per mile, the slowest run I've had in a while.
Why the terrible run? On Saturday, as part of the Luke's Locker training run, I ran 5 miles, including the middle 3 miles in 22:30 (7:30 pace). But I don't think Sunday's bad run was because I was tired.
I think it was something I ate. I munched on chicken enchiladas all day Saturday and had a mint chocolate chip frappuccino from Starbucks around 5.
Ahh , there's the culprit. I'm terrible with dairy.
I don't usually drink that foo-foo coffee. But I had been craving something sweet. I won't do that again before a long run.
