Some thoughts for your next podium shot:
1) What I call "arm balance" - only the winner puts up both arms, everyone else puts up their outside arm
- if not the winner, put your other arm (the inside one) on the small of the back of the guy next to you
- Natural elbow angle: don't have your arm at a 90-degree angle like a "stick 'em up!" pose (I've seen this!), or on the other hand a completely straight arm.. a slight bend looks best
2) Wear your kit. Even if you have to change back into it, please please were your damn kit. Just a jersey is better than nothing, but it looks ridiculous with whatever street clothes you have on.
3) No helmets!! (I've broken this rule, it's easy to forget)
- sunglasses ok, team hats ok
Steve Tilford actually covered most of this on his blog: Podium Etiquette, Let?s Send Joseph to Europe, etc. | Steve Tilford
If you won, make sure you congratulate the other guys up there. It’s only sporting. The guy at the top of the podium, ie the winner, is normally the only one gets to put both his arms up. The guys are either side should just put up one. Preferably their outside arm. If the guy that won grabs the other guys hands, then it is kosher for the 2nd and 3rd place guys to have both arms in the air. You should try to only wear you cycling clothing to the podium. Team kits. There aren’t many excuses for this rule.
