Sounds good. Can we do it in swimming? If so, I've gotta ask: "official" mile races, per FINA and USA swimming rules, or the true mile? In FINA, that would be the 1500m (short course or long course), and in USA Swimming, that's 1650 yards.

Meters: 1609 (64 or 32 lengths plus 9 meters)
Yards: 1760 (70 lengths plus 10 yards)
