Wednesday medium long run (20km) + 5 x 100m strides

Feeling very flat this morning. The lingering soreness from Saturday's hills persists, albeit slowly improving (too slow)! Wasn't until about the seventh kilometre that I actually felt half decent. The GPS was slightly off today as well, to make matters slightly more annoying. It was reading too short, therefore showing my pace as slower than what it actually was. Finished the four laps averaging 4:22's at 131 beats per minute. Finished off with a some strides on the grass.
