So on Tuesday I was complaining that continuing to reduce the speed has been able to reduce the intensity of my runs. Instead, I was going to go back to what I considered a reasonable speed, and force my heart rate to come down at that speed. It's the old brute force method. How did that work tonight? Well, five miles at 7.2 mph on Tuesday finished at 158 bpm. Five miles at 7.5 mph tonight finished at 156 bpm. How's that for messed up? Now, that's well within any margin for error for the measurement, so it's not a definite increase (comparing two n=1 samples is not a great idea) but at least my HR didn't skyrocket. Who knows how these things work sometimes. Maybe the faster speed makes for a more efficient stride, maybe I'm just a little better rested, maybe it's just measurement error. Whatever it is, I'm sticking with this plan for at least a few weeks.
Run: 5 miles @ 7.5 mph
