I do stadiums as an easy-medium workout. Idea is to cheat on an easy day by getting the almost benefits of a hill workout. Hills take their toll on my achilles and for whatever reason stadiums do not. I've mostly been doing brisk walks for stadium workout, but wondering if running would be better for explosiveness. Thoughts?
It sounds as if you have your own answer. Run the for explosiveness, but then you move this from an easyish workout to a more demanding one and therefore risk injury (if you choose to do this back to back with a hard workout). These things are all trade offs. How to get the maximum workout while backing away from injury. The achilles issue would seem to be irritated by running them stadiums as you go up on your toes, whereas I imagine walking them allows you to land flat and not flex achilles as much.
