This is how to transition from the bike to run for the fastest transition ever. With practice anyone can do this in simple steps:
1- Remove your shoes before getting off your bike
2- Get off your Bike at the last possible second
3- Run your bike by the saddle (not handlebars), and un-clip your helmet while running
4- Take off your helmet while racking your bike
5- Put on your shoes
6- Grab your race belt, nutrition, cap, etc in one swoop and put it all on while you run out of transition

That it is. Just practice, practice and practice some more. Anyone can do this an shave a ton of time off transitions. Sometimes winning or losing can come down to a second or two and transitions like this have made all the difference in the world of podium finishes for me several times.
