For me, it depends. Even if I start out with just riding solo (not a group ride) It's pretty common for me to end up riding with one or more other riders who are working at similar effort levels. I've had some really good workouts trading efforts with other riders, and end up a going harder than I would have gone on my own. Even if I'm just doing an easy-tempo spin, I tend to enjoy it more with others riding at the same pace because it immerses me more in the "game" rather than just looking at the numbers. Riders doing a structured workout I tend to leave alone.
