I hadn't run since school, but over 25 years later, thought I'd give the Couch to 5k progamme a go. 10 weeks on, I've run 3 x 5km runs in the space of a week (30:53, 31:45 & 32:01). Unbelievable.
It's been hard work, and not the best of weather and at the moment, I can't imagine ever being able to run for more than 5km... but I aim to do a 10km in the summer, so I'm determined to find a way.
