It was only 20 degrees this morning when I ran. I just could not warm up my lungs. I tried a neoprene mask and the hospital mask, but neither one worked. :(
I ran the first mile in 10 minutes and then had to slow down due to sore lungs for the second mile. I ran 2 miles in 21:24. I walked a half mile and then had to quit.
I need warmer temps! As always, I had a small incline to simulate the outdoors.
