Echoing comments above, I cycle everyday to work; 11 miles both ways, from the SE London suburbs to just off Tooley Street (London Bridge). In these times, I could work from home. I don't for the sole reason (don't tell my employers
) that cycling is my drug fix.
I wouldn't have it any other way. I've been commuting like this, to a few spots around central London, for almost 10 years now. The exercise is intense: I push myself where it's safe to do so. The head (clear) space it gives me is as valuable as the fitness benefits. Coupled with running, at 40, I'm fitter than I was 20.
Yeah, this is a bit 'look at me' and cycling certainly can't improve my facial features (!) but without it, I know I'd be 5 stone heavier, super un-happy and a lot poorer in the pocket. Why waste money in a car or on the train when I can more often than not, get to work quicker and more easily.
The only times I don't ride is when I have after-work drinks (maybe once a month), when it's a 60mph+ gale (rare) or icy (very rare, snow isn't an issue). Or injury (thankfully - touch wood - even rarer).
The key part of that article is routine. Once it's part of your routine, it's natural, it's easy, it's just normal. It's non-negotiable. There are no excuses.
Sweaty or smelly? Shower before you ride, go to a cubicle at work, flannel down, freshen up.
Too long? If it's 20 miles one way, maybe, but even then you can work to it. I'd love a longer commute (!)
Good enough bike? Nonsense.
Dangerous? Only if you make it so. And as pointed out, no more dangerous than being a pedestrian. Or a driver.
