I did my 50th parkrun yesterday and just want to encourage all C25kers, especially those at the beginning of their journey, to think about parkrun. Find out if there is one near you, and you absolutely don't need to wait till you can run a whole 5k to get started. There is always a "Tail Walker" and you'll beat them anyway!
It's a great way to have company on some of your runs. Even though many of us enjoy the solitude of running on our own, it's good to have a change.
People don't care whether you are an elite athlete or you're walk/jogging while pushing a buggy with your dog on a lead beside you. Everyone is equally welcome. It's a very accepting thing, parkrun. Much like this forum actually.
