Should I/Can I change clothes? In sprint and Olympic distance, my tri kit is on me from when I leave home to when I get home after the race. Everything has to work in the water, on the bike and while running, every second spent in transition counts. On the full distance (Iron) scale, you’re not often worrying about the lost minute you spend getting into the most comfortable pair of bike shorts (which would have been terrible in the water, but will literally save your butt on the bike), because being a little more comfortable for several hours in the saddle is worth it. What about the Half-Iron distance though? Is it worth the time? Is it even plausible or is there no opportunity to do it without being arrested for indecent exposure?
