Ok so in january after turning 50 and hitting nearly 17 stone with high blood pressure and bad knees I decide to change my life. Fast forward 6 months of shin splints and pushing my running I am down to 15.9 stone, blood pressure is going down and have just completed the lottery anniversary run, time was not great at just over an hour but I done it. I now want to get to next stage, but what to do. Tough mudder Boot camp 10k any advice would be great. going to gym though bores me to tears.
