Ahh, but you smoke and although I’m 15 stone, you know I can whup yo’ skinny ass whenever I feel like it!
Plus I can eat and store more calories than you to keep going longer….
At the moment you might, but I don’t do hardly any riding, really. Were I to knock the smoking on the head, and do at least 30-40 miles a day, on and off road, you’d have no chance. Speshly on the longer distances. Think about marathon runners. On something like one of the alpine climbs, I’d be carrying a lot less ineffectual ballast, and would have a significant advantage. Plus there’s things like cooling. Having a smaller surface area, I’d again have an advantage.
Don’t confuse fat with power and strength. That comes from muscles. Fat merely serves as an energy store, and then only up to a certain point, beyond which the body will use more energy breaking the fat down, than it produces.
I doubt any of you that are keen cyclists are really ‘fat’. Maybe you’ve got a spare tyre or two, but unless you’re actually obese, then being a bit portly won’t be too much of an issue.
