Interesting about the rubber bands - I'll have to try that. my shoes always drag ( size 47) and so I tend to run to the end of the transition and then put them on and mount at the same place. Coming in I leave them on and take my feet out over the last 100m, resting them on top of the shoes, and then lift the bike and carry it to my spot in the rack once i'm inside transition.

While on the topic of shoes - who here rides races with socks ? who not - and then puts them on for the run? I tend to go barefoot but I only do sprint distances and would probably "sock-up" on a full distance IM or similar.
