Thanks to the “Eye in the Sky” that is Google Earth, I was able to capture an image of the Ironman Arizona transition area for the November 2010 race.This image was taken a couple of days before the race. There are no bikes on racks, and the transition bag area is essentially empty.
Here you can see the network of bike racks lined up side by each, as well as the area where transition bags will be laid out (green), in the space above the bags are the changing tents (purple). There is also a line of portajohns in the bike area (yellow) and a couple right next to the changing tents.
Once you exit the water, you will run east, then south around the far outside of transition. After you pick up your T1 bag, you’ll make your way to the changing tents. After you change into your bike gear, place your wetsuit into your T1 bag.
Now off to your bike! Remember, you must walk through the changing tent. Upon exiting the tent, you drop off your T1 bag, and head for the east end of the bike area.You will run down the center of the bike area, to the row that has your bike.
A volunteer may or may not be there to hand you your bike. Once you have your bike, you run out the west end of the bike area to the mount line, and then ride south through the park to the intersection of Mill Ave and Rio Salado.
If you’re wondering how far of a run it is from the swim exit to the bike mount line, it is about a half mile.
All of the bags are organized by transition: swim to bike, and bike to run, and are laid out in rows by number. It is very easy to run down your row and locate your bag.
