Idea: sports competitions shouldn't constantly be chasing the outliers — fastest, furthest, strongest, etc. Instead, the goal should be to hit the mean average in your class. "Closed bids", each competitor doing their run (etc) solo, without knowing the others' times. Most average wins.

*That* should suit your bimodal distribution.

This is surely a winner. I expect the competitive sports community soon to be queueing up to praise me for this ingenious idea.
