  1. Blocks, then the upright run

    Melissa Jefferson-Wooden's 10.61 at Tokyo on September 14, 2025 includes the reaction and the drive out of the blocks as well as the meters at top speed. On a race this short the start is a large piece of the clock. The all-time list keeps the legal personal best. A radar on one stride would read higher than the race average, and it is not the race.

  2. 21.1 mph is the average

    100 meters in 10.61 seconds is about 21.1 mph from gun to finish, not the speed at 60 meters. Melissa Jefferson-Wooden ran that average at Tokyo on September 14, 2025. Hundredths of a second at this distance are a few centimeters at the line. They are not a different event.
