vaulter

noun

1. A person who vaults or leaps.

   “Indeed, with a world record‐holder or Olympic champion in almost every race, with six milers who have broken 4 minutes, eight high jumpers who can top 7 feet and seven pole vaulters who have cleared 17 feet, there is no way guessing how many Olympic champions‐elect will be on display in the hatbox over Penn Station.”

   “He comes from a family of athletes: Greg, his father, was an elite vaulter for the U.S. Helena, his Swedish mother, was an international heptathlete and volleyball player.”
