IRONMAN 70.3 Northern California is a split-transition 70.3. Your kit splits across colour-coded bags that travel between transitions for you, and your bike goes in the night before. The structure below comes from the race calendar.
Each bag travels to where you'll need it.
On a split course you never return to where you started, so your kit is split across colour-coded bags that get moved for you while you race.
