For someone of reasonable fitness with a good base it represents no more then seven hours of riding. There's a whole host of advantages doing this rather then the lesser gimmick of one a month. Come the start of spring you'll be trim having had a good winter base and be hardened to the elements not to mention knowing what works in terms of kit and nutrition. You people should be itching to get started - in fact shall I bring it forward by 3 months? The rest of this month can be spent making sure your bike is in good nick and sitting down explaining to loved ones what you'll be doing over the next year. Shall we start in October?
'For someone of reasonable fitness with a good base it represents no more than seven hours of riding'.
You've been reading the comic, haven't you, spouting all that gibberish. No-one doing the challenge doesn't have a reasonable level of fitness, and I for one can't do 15 mph for seven hours, on open roads, solo (EDIT- though I've come close more than a few times. 123 miles at 14.4...). Doesn't make me unfit. Done 75 in 5 hours rolling, with strong assistance (stronger than most- serious level audaxers, multiple LELs and PBPs, each). And then I did another century. I'm not going to get any trimmer, thank you very much. No excess fat here.
And, the plain fact is, in Cycling Life, a century a week isn't that hard. I've done multiple back-to-back centuries, I've done a 223 mile day, over 500 miles in a week a couple of times. So's Ian, so have a lot of people of my acquaintance.
In Real Life however, somewhat different. It'll be a lot harder..if you work regular hours, five or six days a week. If you have any kind of non-cycling social life. If you want to take any holiday whatsoever without a bicycle. If you're not single and/or have children. Even if you are single, and you might be called upon for anything else at weekends. If you ever get sick or become injured. And let's not forget the Great British Weather. It snows, it rains, it blows a gale. But perhaps you have pro-level fitness, an independent income, the ability to fly off to warmer climes any time you feel like it, and no interest in anything other than cycling...? As Mr Abraham and Mr Searvogel would tell you, Real Life has an unfortunate habit of biting you in the posterior no matter what you do to minimise its disruption.
You really, really want a proper, sustainable challenge but think a mere century is too easy for you?
