i read the rules:

5.11 Bicycle Specifications

(j) there must be one working brake on each of the two wheels.

i got brakes, but has it been done? i will be doing a duathlon this summer and want to rip the course apart on my track bike...has any of the veterans seen track bikes on the course?

that is soo kewl

Good luck

Peace
Tyler

I've seen fixies in a couple races, last year - but these were non-USAT sanctioned races.
I'd ask the RD first, to ensure the bike is race-legal, then GO FOR IT!
