A great form of cross trainer for us runners. Keep that heart rate in Zone 2. You might feel like RPE is higher, as it’s a tough exercise, but a good opportunity to really improve your aerobic engine without the heavy impact of running.
A threshold session in disguise. So whilst your pace will be Zone 6: 5k, because the reps are so short, you should find your heart rate stays in Zone 5, and below your LT2 (if you have that data). You can choose to run this session specifically to HR if you prefer. If you start to struggle, increase recovery slightly.
