I was so pleased last week at running for 20 minutes WK5R3 and looking forward to graduating at the end of the month/early November. However, never count your chickens before they are hatched so to speak, I had a slight pain almost like a bruise when you touched it on the left side of my right knee I did WK6R1 on Sunday morning no problems, WK6R2 Wednesday morning knee hurt slightly before I started but it wore off as I did the 5 minutes warm up walk, run was OK as well. Then during the day as I sat at my desk working each time I stood up to walk I could put no weight on my right leg because of pains in my right knee it got progressively worse as the day went on. I don’t think I will be able to do the WK6R3 Friday morning as I don’t want to aggravate my knee. Like most people I suspect I need better running shoes as I run mainly on pavements and hard surface paths. I wanted to wait until I had progressed through the plan to make sure I had the ambition and drive to follow the C25K plan to the end before buying new trainers. I have an old, very rarely used, pair of Reebok classic trainers which are very comfortable so no problems with my feet but I suspect that I need the shock absorbing qualities of modern trainers to protect areas like my knees. Believe it or not I was planning to go this weekend but it looks like mother nature caught me out first. However, reading all the various blogs on where to buy running shoes I think I will try my local Sweatshop store to make sure I get the right shoes for my running style.
