Well i never, that wasn't so bad at all.
The night before the run i went to bed worrying about it. How can i possibly go from 2x 8 minutes to 20 minutes, that's ridiculous surely?
Up on Saturday morning, read a post from sarahvictoria in the same predicament and pulled on the running shoes.
Tried to get some positive thinking and big deep breaths going during the warm-up walk and off we go.... the first few minutes were a bit messy but after that it was ok, really, honestly!!
The ageing body seemed to say 'oh well, despite all of the aches and pains i've given him, he's obviously not going to give up, so i may as well jump in and give him a hand'
And there it is, 20 minutes later and i'm still going and feeling fine.
Maybe this plan does work after all ........
