Horses for courses really. Some people want to train and train in sunny warm places. Some aren't training for anything. Personally I just pootle around. Im not interested in how fast, and far I can go, I just pootle. That makes me happy.
at the same time, if someone has a job where they work unsociable hours, works hard, is competitive, and wants to train somewhere in the sun, then go for it and enjoy yourself I say. They work hard to earn they're money and can spend it on whatever they like. Good luck to, them. I'll carry on pootling between 6 to 14 miles on my own. Thats what cycling is all about after all, enjoyment, not torturing yourself or trying to keep up with the jones's. I'm old enough now that I'm not bothered what anyone else does. Enjoy.
