After graduating c25k in December last, I'm still getting out there mostly every other day and doing 5k - sometimes a bit less and even 6k a couple of times. I've discovered the joy of running slowly. I think I'm more interested in endurance than speed (not that I've ever been fast). So I think I'll slowly try to build myself up to 10k now that Spring is allegedly just around the corner. I'll be following JuJu's 10k plan from the Bridge to 10k forum, or at least a modified version of it with more shorter runs squeezed in just to make sure I don't go too far too soon. There's no rush. I've also found some grassy trail that I can incorporate into my runs and gets me off the unforgiving tarmac. That makes it much easier on the old knees. I want to be able to keep doing this as long as I can. I just enjoy running. I'm a reformed couch potato and now couldn't do without the buzz I get from running.
