I’m 100KG and back in my army days I was 85-90 KG’s. Certainly I had no problem running back then as I was an infantryman. I never enjoyed it however and always wondered how to improve my style.

You need to check out the POSE running technique.

POSE RUNNING

It really is the best advise on running I have come across & I expect to get back into it this summer
