I'm doing my first triathlon in two weeks. It's very short, only 500m swim, 15k bike, 5k run.
I'll definitely be using my new road bike, but not so sure about the pedals. Although I love the Look pedals, the shoes I use with them have that ski boot type of buckle on the top strap, and it's hard enough to get the strap into it even standing still, let alone while trying to pedal. Plus, I'm don't know how people manage to start with the shoes in the pedals as that makes the shoe side flip upside-down from the weight.

So, I guess I'll be using the SPD pedals froms my touring bike and my old Lake lace-up shoes with those spring thingys to tighten the laces without tying them.

Or is there a way to use the Look shoes with the awkward buckle? Anyone done that? I know triathlon cycling shoes have all velcro straps, but I don't want to run out and buy a whole new pair of shoes for this one event. If I decide I really like triathlons I might do that, but I want to decide that after, not before.

Oh, and should I carry an inner tube and pump on the course, or would that be overkill for a 3k loop done 5 times?
