I asked a question on here last week (thanks again for all the answers!) about whether I should progress to Week 2 when I did the walks in week 1 but they weren't brisk, and decided to go for it. I bared the posts in mind and possibly stretched the definition of "light jog"! However, I finished all the runs and it still got me out of breath and sweating, so I think I'm OK. I think if I'd have kept the pace of my jogs in week 1, I wouldn't have been able to finish. I'm really not sure how light these jogs are supposed to be.
Again though, these walks I'm doing aren't brisk! I think it's a mix of being too tired to do them briskly and that in the past, brisk walks have put a strain on my calves so I'm wary this would affect the rest of my run. What do you guys think? Will this hinder my progression?
