I completed C25K towards the end of 2012 just in time for the 5k run I had booked. I thought I would just continue running but I found that without the challenge of something to run towards I made excuses not to run although I continued to go to the gym.
I restarted the program a few times during 2013 but never managed more than a few weeks.
So this year I have booked myself a 10k run in May (first date that coincides with a day off on the weekend) and strapped on my running shoes. I have completed W3R1 and 2 this week, one more to go. It didnt feel too bad. I really enjoyed them too which annoys me that I didnt have the discipline to keep it up but I think I must be someone that needs a goal to work towards. Fingers crossed!
