Run... and sweat.

It's really hot out. I waited until 9 to run tonight because it was unbearably warm out earlier. I probably should have run this morning.

Five minute warm up followed by 4x 5t, 2r. I tried to run steadily, maintaining the speed that I started each set with. I ended up running my tempo speed closer to 8', rather than 9'. My cool down pace was between 10' & 11'. I felt good about the run. I felt that it was difficult. I felt that my heart rate was good (aside from two stop lights, one in the first set and one in the last set). I'm not sure that I went ... slow enough. I don't know whether to slow down or keep the pace where I set it.
