I'm just looking for some advice on walking/running speeds. I am doing C25K on a treadmill at home, and I've completed 2 Week 1 sessions. My treadmill is in Km/h, so I have been walking at 5km/h and then running/jogging at 7.2km/h and I find this manageable.
Should I be pushing myself more, or do these speeds sound ok? Any advice would be greatly received!
