Running intervals 25:00  4.0 km (6:15 / km)
shoes: Asics GT2150 (Feb 11)
4x1km in the arboretum.
On Wednesday I noticed that even though I felt like I was going pretty hard my heartrate wasn't really going much higher than 160-165. So today, instead of focusing on just trying to run faster, I was focusing on trying to raise my heartrate. Not sure if that makes sense to anyone else, but I guess I just mean instead of concentrating on turnover or anything else I was focusing more on just putting more effort in.
It seemed to work, my heartrate definitely got higher today, but that could also be because I was doing a shorter and a bit more intense workout.
Happy with times, goal was to go under 3:20. I think I can be even faster in a few weeks if things go well, and of course with light shoes/no orthotics. Thought I could go under 3:10 on the last one, but ran into some considerable GI trouble halfway through.
