i still use my hybrid fairly often for:

1. riding with my boys - they are 6 and we like to bike to their favorite playground, about 3.5 miles from home. I think we are going to do a family ride that is part of a century weekend put on by a nearby bike club. It is 8 miles and I think they are up for it.

2. taking my daughter for trips in the burley. there is no way I am hooking that thing up to my carbon fiber road bike.

3. quick errands around town. I have campus pedals on the hybrid, so I don't have to wear bike shoes to run over to the pool for a swim workout or for a quicktrip to the grocery.

I have had my hybrid for 10 years and owned a different hybrid for 3 years before that (stolen). I have done the MS30 and MS60 rides in NJ and the Late Ride in Chicago all on hybrids. In training for my triathlon I did not always have free time to get out on my road bike, but I could do my mileage with my youngest in the trailer. So I do still use a hybrid for training, even though it is not my first choice.
