Similarly ... tri shorts for an IM? Past two IMs I've worn bike shorts and run shorts for the respective bike and run legs of the race. I've always done half IMs in a tri shorts and top - no changing. I can't really imagine a full 112 in tri shorts, but I'm considering it. I'm a klutz in transition and don't feel like dealing with two changes of clothes, but I fear I'll regret not having full bike shorts on. Any thoughts?
