I believe you shared that as part of your Comrades marathon training you worked up to powerwalking an hour on the treadmill at 15%. Is this correct? Can you please detail some of the specifics?
I am looking to add some hill training to my running and wanted to include this workout as well given the challenge of hitting the hills in Ohio. I tried it on the treadmill yesterday at 15% and it was really difficult to walk at even 1 mph. What speed did you work up to? Were you focused on time on the treadmill or speed or both?
Anyone else use this as a training aid?
