Concrete/road run tempo (4 x 4 @ 9:40) 49:00  4.75 mi (10:19 / mi)
This was a surprisingly good run from warm up through cool down. The first interval was 9:35. Each one got a bit slower with the last one at 9:45. With just 1 min rest, I got tired faster.
I did yoga yesterday evening and tonight. I think it helped my flexibility and my breathing.
