Parkruns are a great introduction to running. The free weekend 5km runs are open to everyone, whether you can only manage a few yards or will barely break out into a sweat. Kids can get involved too, with junior runs of 2km for 4-14-year-olds. The events are run by volunteers with runners timed so you can monitor your progress.
