World record ????
 

Anyone know of the largest connected peleton to ever group ride together? Say 100 or more ?

Critical Mass, if you consider that as a sort of peloton (which it's not). Chicago Critical Mass has 500-1000+ riders every month, and I bet some cities have bigger ones.

As far as professional races go, nearly all races have well over 100 riders on the start list - usually 160ish.

Budapest had a CM (Critical Mass) in excess of 22,000 (yes, thousand) not too long ago.

It makes the US Critical Mass (plural) seem pathetic.

EDIT: Quick search on Google - estimates between 24k and 30k in number. But, again, this is not a peloton.

not a race either, but you should see the start line of this one...

MS-150 (Houston to Austin) fills up at 13,000 every year.

I hope they do staggered starts on that one. If not - what a mess! The Palm Springs century is anywhere from 8-10,000. The freds would just be piling up if there wasn't one.

this is not a race either, but try to tell that to some.... riding 8 wide....

Yeah, I won it last year ;)
