If transition is the 4th discipline of triathlon, then logistics is the 5th. Just getting to the start line can be a real ordeal for some events, especially if a wetsuit swim and a flight are involved.
I like to lay everything out the night before, especially with the traditional early starts of local, open-road races. To help with this, I’ve made a handy triathlon packing list, setting out all the tasks I need to achieve. I normally drive to my races, so also need to prepare the bike rack, but otherwise I think the list is pretty general. If you’re packing away from the internet, you can find a downloadable, printable triathlon packing list here.
