Run for the kids

Is on tomorrow in Melbourne I have signed up for the short run,5.5km, this is the third run in our challenge to do one 5km event each month for a year. I'm just hoping I get the right event if not I could end up in the melbourne ironman challenge, which starts with a lazy 3.8km swim, then a few k's on the bike, 180 or so and then brings it home with a full marathon just to make sure they are really challenged. I think I'll stick to the 5.5km.
