In Paris, Erriyon Knighton likely will face an old and challenging test once more: beating three-time 200m world champion Noah Lyles.

Here's how the 20-year-old track and field star is preparing to meet his biggest foe.

Who is Erriyon Knighton’s biggest competitor?

Despite his long list of accomplishments, Erriyon Knighton has one hurdle he has yet to overcome: three-time world champion Noah Lyles.

After gaining a lead on Lyles initially, Knighton slipped just behind him in the final few steps of the 200m race at the 2022 U.S. Championships, falling to a silver finish. While Knighton was earning bronze at the 2022 World Championships, Lyles was again grabbing the top prize. 

Knighton’s first gold finish, from the 2023 U.S. Championships, came in a race that Lyles opted to skip, given his automatic bye as world champion. 

Should the two stars get a chance to duke it out once more, it'll be a can't-miss race.
