Hey, it's cool if you want to use your mtn bike for the tri. I did until i got meself a road bike.

At the tri's i've done down this way, there's always someone on a mtn bike with slicks.

Actually I think i saw someone on a mtn bike at the 1/2 IM in may...

Have fun! Don't be put off by all the nice bikes while on the course, just go out there and do the enticer distance!
