Jeez. Try strapping a 10kg weight vest on and commuting 30miles!Hey everyone
About me, because I know this very much depends on the person: male, 72 kgs, 5'11, not unfit.

Haha, I see a few people who look forward to journeys they previously thought were a slog!
How do you find those hills in the winter?
Hills are what keep you warm as the temp heads below 5°C.
Personally I wouldn’t be worried, get a roadie, try the ten miler, see how you feel.
See if you can find a slightly longer, flatter route if you’re really concerned. I’ve found that I have to try a few different routes to find one I want to use.
As with all things commute; prepare well, plan for disasters, leave as much kit and gear at work as you can. You don’t want to be buying new tyres and tools in your lunch break as I have had to, and you don’t want to be hauling anything around on your back if you can avoid it.
