What the Duplantis Family Story Teaches Us

A US pole-vaulter father who coaches all four children. A Swedish heptathlete-volleyball mother who is the reason Mondo competes for Sweden. Three siblings — all of whom became pole vaulters or athletes. A 6.30m world record set at age 25.

For every family — large or small, famous or otherwise — the Mondo story carries the same lesson. Some families are entirely focused on one sport. Four Duplantises across two generations have pole-vaulted — and one (Antoine) is a baseball pro. Write down which families turned a household entirely into a track-and-field training programme.
