I started my C25K last May, and have now got to the stage of running 7k twice a week, with the odd park-run when timing permits. I’ve even entered the Newport 10k in May to celebrate my year of running.
However, a few weeks ago I nearly quit, I have been suffering shin splints on and off, mainly my left leg, but had a run and half way through was in agony, my left leg was burning. I couldn’t see a way forward, I tried compression sleeves, but they didn’t work.
Then I found this guy on YouTube , I’ve no affiliation or connection, but his simple exercises have done the trick, and are so easy to maintain.
If you suffer shin splints, take a look at this link, it helped me to keep my running faith.
