First post, and I will say that the C25K changed my life. (Sorry if this is the wrong place?)
I had never run before trying the C25K late last year but found out about this and after some serious thinking I actually gave it a go. To be fair the timing was spot on for me when I found out about it as I had been on a well balanced diet and was losing weight for a few months and was walking 4 or 5 miles every evening which did give a great foundation for this.
For what its worth my personal running experience is this:
Week 1 of the C25K was mentally the hardest week by far for me. Did ok though. Felt a massive achievement running for 1.5 minutes at a time. Emabressment factor also came into this for me but running through the cold dark wet winter evenings meant I was more or less on my own. I am now confident enough not to worry and even enjoy running in daylight, took me a while though!
I then did all subsequent weeks up to the end of Week 4 as normal, but by Week 5 Day 2 I was VERY worried about having to run for 8 minutes solid, twice with a 5 minute walk in between. However I went out and did it and when it said "5 minute walk" I kept on running. When it said "run" I just kept running. When it said "cool down walk" I kept on running. This was the defining moment of my running. I had run for 26 minutes solid. I then knew I could go out the next time and try to do a solid 30 minutes, which I did. I did this a few more times and soon felt more comfortable doing it. I then mapped out 5k as best I could using mapmywalk and ran it, and it took me about 35 minutes. I then did the same route 2 or 3 times a week and can now run the same route consistently in around 28 or 29 minutes. I also found out about a proper 5k race so found the exact route, start, turn and finish points, and ran it. First time (early January) was nearly 36 minutes. Ran that same route last night and did it in 28:52 (which was good as I a little felt off my usual pace as my legs were feeling tired from the start, been a hard few weeks). In between this I have gradually crept my distance up to include 1 long run each week, which means I can now run 10k in just under 1 hour. So, long story short, the C25K has changed my life, and I have encouraged a few people to give it a try if they feel like they want to start running! (I am still large in build, but 10 times better than even 6 months ago (around 8 stone lighter than I was a year or so ago and now fitter than at any other point in my adult life). I am now entering that same actual 5k race next month, and also entering a 10K in September which gives me another goal to aim for.
Well done to anyone else who is going through the C25K, it is hard going at times but hopefully you will get there and realise that once you have built up some stamina doing the C25K running both physically and mentally will get much much easier!
