When I went to a duathlon last weekend, I spent most of the time watching what people did in transition. Granted they were not coming off swimming so I'm sure a tri transition is different, but it certainly was interesting. I did not see one person sit down to put on their shoes and many, if not all, had quick tie-shoe things on their runners and velcro closures for their bike shoes. A number of the younger men had their bike shoes already clipped into their bike and they ran with stocking feet to the bike portion, jumped on and started riding. I guess they must have reached down and tightened the velcro on the ride. Weird. Looked too tricky to me. But anyway, the point is, they all did up their bike and running shoes while standing up.
