Mostly I ride on my own, and don't talk to myself... but on slow-medium pace training ride (like Knotted I often sing to myself).

On a slow-medium pace ride with others, we usually ride in a pace-line so no talking. When with my partner, we often ride side by side and chat - one of the few occasions we are uninterrupted by children!

One of the women I train with most often prefers to ride beside me on and we "talk shop" alot - often our rides will be extended lunch breaks or if we can leave work early.

On medium-fast training rides, nope, very little talking... usually in a pace-line anyways.

In a race? Nope, just too busy trying to breathe!
