Are fat people faster downhill?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Are fat people faster downhill?

No joke.I've gained 20 lbs and i seem to go faster downhills on group rides than the skinny ones.I'm talking no peddling,just tuck.I did 41mph today on a hill I never broke 40 before.BTW I'm easily the slowest going uphill.

That is absolutely correct. Per the laws of physics. Same problem here. Though I have lost some weight and learned to climb better. Still...

Not that there won't be someone coming here to note that all things fall at the same rate (in a vacuum) therefore this can't possibly be true. Then I'll be forced to show the math showing a heavy person will indeed fall faster than a lighter person. People will then utterly fail to understand the math (most won't even look at it and half of those who do won't understand because: algebra) and argue non-stop that feathers fall at the same rate as a hammer on the moon, which, of course, is a total non sequitur because air resistance is the whole reason why things top out at a terminal speed rather than accelerate faster and faster and faster and faster and thus to leave it out is like leaving the sausage out of a hotdog or the beef out of a hamburger: you don't have a hotdog or a hamburger anymore, you just have bread.

My best strava times are on descents while commuting on my steel bike with a laptop in my backpack...so yes....fat people go down hills faster (assuming they have the legs to make up for it..which they normally won't compared to a fit rider). In other words...if a 250 lbs. guy and a 150 lbs. guy coast down a hill, the big guy wins...unless the more massive wind resistance counteracts the extra speed..which it might. So there.

I try to make my way to the front of the rotations for the downhill sections of the group rides, as if I don't, I need to sit up and catch wind on the downhill so I don't run over all the skinny guys in front of me.

If a fat person descended faster last time we had this discussion, he still would now.

Unless he has been on an effective weight loss program.

The he wouldn't be a fat person any more, would he? And the question wouldn't apply to him.

I would think a heavily muscled but thinner person would be much faster.
I worked with a man who was 6'5 rail thin but an honest 240, with tight kit and a good tuck I bet he would scream downhill.
Me at 6'2 265 but fluffier and not wearing tight kit, would be fast but not fastest.

You sure took the fun out of this thread quickly. You need to realize that those of us in the Southern Hemisphere aren't quite out of winter yet and still rely on threads such as this.

Most fat people I've seen on descents take the time to rest after killing themselves on the climb. I make up for any disadvantage by pedaling all the way down.

Most fat people I see are sitting on a couch, shopping at the mall, or wailing at the hospital. I can't recall ever seeing a fat person on a group ride. Also, I would wager that fat people have more skin than thin people, so I don't know which group you are comparing to when comparing fat with "skinny" riders.

I do think that heavier riders descend faster.

Im a muscular 265lb Clyde, you'll get me on the uphill but i'll blow ur doors on flats and the downhill.

Its a vicious cycle.

Top speed this year 46 mph, dont want to go much faster on a bicycle frankly.

Girls aren't allowed to pass me ...

I am not fat, I have good descending muscles
And yes larger people do descend faster, go ride your bike and test it for yourself.

Maybe the fat on a person naturally conforms to a more aerodynamic shape than the more rigid muscle and bone of a skinny or fit person allows for. It's like a built in body fairing. Probably should be banned by the UCI as an illegal aid.
