Before Armand Duplantis, no US highschooler had ever vaulted 18 feet indoors (9 others have done it outdoors). Challenged by Olympic bronze medallist Sam Kendricks who put up a video of himself clearing 18 feet five times in the span of 30 minutes, Duplantis below clears 18 feet 10 times (out of 11 tries) in the span of 28 minutes.
Ridiculous.
