For those with tri specific bikes, do you train with them on a regular basis or do you have a secondary bike such as a road bike in which to train with?

I'm curious because I have my old road frame hanging, but i'm having more fun with my new P2C.

Since I pretty much do triathlons and the occasional non-UCI TT, I do nearly all of my solo rides on the tri bike. Only when the weather gets foul, I need a super easy recovery ride, or I'm on a group ride do I use my road bike.

P2C is a sweet bike, no reason not to ride it if you want to! :)
