For those who ask whether they can start C25K at 50, 60 or whatever age the individual considers is getting on a bit, take heart from the Bushy Park parkrun last Saturday, when a group of around fifteen over 80s came together for the occasion. Most of them had an affiliation with a running club, but there was at least one individual late starter (me). The fastest did the course in 28 1/2 minutes and a lady in the 85-89 range took a little over 46 minutes. My time was 43.20 minutes. I started C25K just over 2 years ago - I'm not sure why - and it has been transformative. Rignold might include a question about starting age in his list. The answer is that there is no limit - if you're fortunate enough to be able to walk, have a go.
