It shouldn't mate, I was in the Army and was part of the athletics team and then ran for Sunderland Harriers for a season after I came out, I've always kept myself fit.
But anyone who can get out and run 5k in any time deserves credit.
I'm wowed by the marathon being completed in under 2 hours, under 3 minutes a kilometer, I couldn't sprint that fast, never mind for 42 kilometers.
Don't run for anyone else except yourself, and if you can find a group to run with and support and inspire you even better.
BTW I was shit at football, ask @D.A
Thanks mate, good message and advice
