In contrast to the majority of miserable, anti-social, Victor Meldrew types above, I much prefer to ride socially in small groups when I’ve got the time. Other people notice different things about their surroundings and often help you push a little harder than you might otherwise. I especially like it when others organise rides (my group had a roster) that way the rides is a nice surprise.
On the flip side, I much prefer to commute alone…others don’t seem to share my 30min-heart-rate-must-not-drop-below-160 approach to commuting. If I don’t arrive at work unable to speak due to exertion, it’s been a bad ride.
At the weekend I’m more relaxed. 🙂
