You've never heard of the infamous hipster barrier technique? It comes from track cycling, like the track stand and its a useful way for cyclist who don't actually 'cycle' to win races.
I'm not uppity, they should definitely do it, it would be a great experience and an even better chance to feel at one with their bikes. My point about being a pain in the ass is, if they are gonna just give up and walk (or if just one of them is) then the organizers have to wait around, insure that they are safe, not holding up traffic, etc, etc. Thats all totally fair enough if the guys are trying, but as I said earlier, trying to do a 200km in the wicklow mountains on a fixed, means training for it.
don't you think you're taking this a little too seriously given you're not actually involved in any way?
