Sprinting/jump performances are invalidated for world record purposes if there's over 2.0 m/s of wind assistance. There is no rule for marathons. | ||

There is a rule for marathons to counter wind assistance, but it's basically that the finish of the race needs to be pretty close to the start. | ||
