I started doing 5Ks in January, but have only walked them so far. I started the Couch 2 5K program 3 weeks ago, though, so I could start running them and hopefully work up to at least a half-marathon by the end of the year (my goal is a 5K every month this year and a half-marathon in December). By the time I finish C25K it will be 9 weeks of training. That'll leave me another 3 weeks that I can use for whatever, so I'll use that time to put as many miles on my nikes as possible.
