I started c25k at start of October 2014 & got 4 wks in before having to give up due to injury.
It was all probs with my left side: foot, knee, back.
Thanks to a great chiropractor things seem better.
I also, on advice of a physio, got fitted for some new running shoes as it turns out I have collapsed arches.
The guy at Sweatshop Chill Factore store was great at getting me sorted with new trainers. He showed me the video of my gait when running & indeed my left foot rolls in much more than my right. Hence probably all the problems with my left side!!
I am on W1R2 again now & fingers crossed my left side seems ok. Let's hope these new trainers help. I'm determined to complete c25k this time. Just very nervous about injuries coming back.
Moral of the story: get yourself fitted for the right running shoes!!!!
