It was 1 degree C (34 F) when I started the first lap this morning. We had 2-3 cm (1 in) of snow on the ground, so I ran on the road.
It didn't start feeling right until I'd done the first 4.9 km (3 mi) lap. I sped up somewhat for the second lap, then slowed again slightly for the third lap. The fourth lap I ran hard enough to build up lactic acid. Then I started the fifth feeling the same as the first, out of rhythm, stiff legs, though I was also a bit tired. My heart rate seemed to stay higher than necessary on the fifth lap.
I wanted to see if I could recover after having too much lactic acid build up. The answer seems to be somewhere between yes and no.
This 24.5 km (15 mi) run was at a faster pace than 21 km (13 mi) two weeks ago. My guess is that I'll enjoy running long on Sundays more when it starts warming up. That run two Sundays ago was definitely more fun.
