I don't think the tailwind was strong enough to make drafting in the bunch significantly harder. It was supposed to only be about 15km/h - that's not going to make following 30 guys noticeably more difficult. But it was still enough to effectively make the race shorter and so it was a bit less of an endurance test than it often is. 22 riders finished within 12 seconds of the winner, and there were a lot of non-big names in there. I think that suggests, even taking into account the slowing down of the front group in the last 500m, that it was a pretty easy edition to ride.Netserk said:Tailwind and fast race = hard(er) to stay in the bunch.
Headwind and slower race = Easier to stay in the bunch.

Yes, but the point is that the fractionally greater amount of effort riding in a bunch in a lightish taliwind; is greatly outweighed by the fact that the tailwind makes the race some 10-30 minutes shorter in duration. The size and composition of the big 2nd group at the end tells you that it wasn't an especially hard race to sit in and follow wheels - at least by Roubaix standard.Netserk said:Lol, ever had physics?DFA123 said:Netserk said:Tailwind and fast race = hard(er) to stay in the bunch.

It's not the tailwind in itself that makes it harder to sit in the bunch. It is the increased speed it causes (when it has full effect on the race speed). In two bunches riding the same speed, it is easier to sit in the one with a tailwind.
Tailwind reduces air resistance at a given speed, and actually decreases the drag at a given wattage for the rider pulling the group.Netserk said:Lol, ever had physics?DFA123 said:Netserk said:Tailwind and fast race = hard(er) to stay in the bunch.

Aren't you both saying two slightly different things there? I think you are both right. Netserk is right that the same speed is easier to follow in a tailwind than a headwind - e.g. it's still easier to go 40km/h in a peloton with a tailwind than it is to go 40km/h in a peloton with a headwind. A you are saying that following a rider putting out 400w is easier into a headwind than a tailwind - which is also true. They aren't mutually exclusive arguments are they, or am I missing something?Red Rick said:Tailwind reduces air resistance at a given speed, and actually decreases the drag at a given wattage for the rider pulling the group.Netserk said:Lol, ever had physics?DFA123 said:Netserk said:Tailwind and fast race = hard(er) to stay in the bunch.

If two pelotons are pulled by a rider with the same aerodynamics with 400W, sitting in a peloton with headwind is easier than a peloton with tailwind.
I'm being an 'ant ****' I know
Anyway, I think time and place of tailwind matters a lot more.
I'm not questioning that. Its just that speed depends on wind and I wanted to give a clearer exampleNetserk said:I know the physics, Red Rick. Read the post again.
