I was to do a 12 mile tempo run today -- 6 miles out at long run pace, and 6 miles back at tempo (faster than marathon) pace. I only got the first part.
It was hot out -- for March or any time. It was about 22 degrees in the shade, but with the sun it was likely around 26 or 27 degrees. By the time I made it 6 miles, I was overheating in a serious way. I called Jenny from Clarke's to come pick me up. Here are my splits for the 6 miles I actually completed (I was looking for 8:30/mile):
Overall, I took 50:34 to run 6 miles -- an average pace of 5:15/kilometre (8:25/mile). I was supposed to step it up to 7:31/mile on the way back, but there was no way that was going to happen. I could really feel my right hamstring after that first mile into the wind, so pulling the plug at 6 miles wasn't a terrible decision.
I decided there that I would not run this weekend -- no easy Friday run, no long run on Sunday. It was time to give my body a break.
