My first was begining of April this year. A sprint with a short swim.
I understood the rough definitions as:
Sprint = 750Meter swim, 20K bike, 5k run
Oly = 1500 Meter, swim, 40K bike, 10k run
1/2 iron = 1.2Mile swim, 56 mile bike, 13.2 mile run
iron - 2.4 mile swim, 112 mile bike, 26.4 mile run
I know that there are many
(infinite?
) variations on the theme.
For example, my first was a 300 yd swim, 20k bike, 5k run
My next will be: 375 meter swim, 1.5 mile run, 20 K bike, 1.5 mile run, 375 meter swim
(a strange one... they called it a double sprint...
)
The other one I'm planning is a 1500 meter swim, 20k bike, 5k run. The swim is with the incoming tide so they CLAIM it swims like 750...
