Just here to check in and say that yesterday I completed the C25K program and my final run actually felt quite easy - definitely made me feel capable of moving on to more challenges. But getting here wasn't easy - my path was complicated by injuries and inflammations which caused me to abandon the program twice in the past. There was an explanation for that. 18 months ago I was diagnosed with Ankylosing Spondilitis. Prior to that I was diagnosed with Ulcarative Colitis (the two often manifesting together). Before that I ws diagnosed with epilepsy - all this in the space of about 5 years. In addition to this I had 2 surgeries to fix two separate spontaneous pneumothoraxes leading to weeks of recovery each time. My own GP described me as "unusually unfortunate" which made me think, considering it came from a guy who makes his living from the unfortunate! There is a point to this dribbling - if you are finding the program challenging please don't give up. It really is designed to be achievable and the greatest challenge with this program really is in the mind - I have seen that most clearly in my own experience. Keep following the program, keep your chin up (literally!), obey the rest days and respect any aches and pains - your body will tell you if you are doing something wrong or too much (knee pain can and will put you out for a couple of weeks if it wants to!) .... and you will complete this and be setting your sights on half marathons in no time. I thought I would never be able to run - I couldn't do it when I was 15 and in perfect health - and I'm doing it religiously now, at 35 and full of imunosuppressants! Good luck all!
