I've just done W1R3 and I'm wondering what speed people do for the brisk walk and the run. I'm currently walking at 6km/hr and jogging at 7.5km/hr does this seem about right ? I also do it on a 1.5 incline to try and mimic wind resistance and the outside isn't complete flat.
Does this sound about right ? I don't know anyone else doing it in the gym, but with it getting so dark earlier it's my only option
