How about something along the lines of "How do You Do It?" - the idea would be to follow a 'typical' triathlete through a 'typical' week. Triathletes are pretty well known (at least by other triathletes) for time management and finding ways to cram training into the nooks and crannies of everyday life - it might be of interest to follow somebody for a week and see how an actual person does it. I'd say, focus on a decent athlete - not a superstar, just an AG'er who is committed to training and works hard to do the best with the tools and time they've got. A diary of sorts, if you will.
