Do running prostheses, also known as blades, give sprinters an unfair advantage over biological legs? And does the increased blade length allow sprinters to go even faster?

American athlete Blake Leeper, a double amputee, is already a Paralympic silver medalist and world record holder, and now wants to compete in the Olympics.

But after the rules changed in 2018, the blades Leeper had been running on for years were deemed too long for competition.

Instead of shortening his blades, Blake took World Athletics to the Court of Arbitration for Sport, arguing that their measurement system was not only “discriminatory”, but that he believed the Olympics were just “not” ready for a disabled man, not just to compete, but to win. “

He lost his case. Meanwhile, World Athletics strongly denies its claim that the rules discriminate on the basis of race.
