When a given swim calls more on endurance than on outright speed, it is the more likely to be considered a long-distance swim. Long-distance swims, however, may take place in pools, such as the 1st official 24 hours World Championship in 1976 won by Peppo Biscarini with a record of 83.7 km (24 hour swims in a 50 m-long pool) or the current 25 ...
The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by speed. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.)

Long-distance races run at altitude, with less oxygen available to the athlete, have been shown to be to the athlete's disadvantage. In road events, the course is not required to be a circuit, but the overall decrease in elevation between the start and finish shall not exceed 1:1000, i.e. 1 m/km.

"You get a lot more muscle recruitment overall when you run faster than when you run slower (for longer)," says McGrath. This works the fast-twitch muscle fibers, which help for quick movements.
Technical-suited Amaury Leveaux set world records of 44.94 seconds in the 100 m freestyle, 20.48 seconds in the 50 m freestyle and 22.18 in the 50 m butterfly, spending more than half of each race submerged, more than any of his competitors.
