I joined a gym this time last year, mainly to use the swimming pool & part of the induction was a session to show me all the machines, treadmill being one of them. I couldnt run for any more than 1min 40seconds on my own. thats where c25k came in. I searched the net & as this was on the NHS site I thought it would be a healthy plan that was achievable. anyway, graduated c25k with no problems, then did a bridge to 10k plan just before christmas & now using the Bupa beginners 10mile plan & am just over half way through. thats why I started. to run longer than 1min 40seconds & I was so over the moon when I ran that first whole 3mins!
