It’s with some caution that I embark on this 10 week course with Jasyn. The background is that I’m a keen runner, 50+ who is gradually getting slower and picking up a few injuries along the way. I need to get some treatment for a calf injury that’s stopping me from running and to kickstart my enthusiasm and see whether I can lose some extra pounds around the waist and shave a few minutes from my 10k time. Can it be done? Is Jasyn the man?
