The Spartan season kicks off on the sun-drenched coastlines of Hvar, Croatia, where speed rules. Athletes battle for the inaugural 100M World Championship, with Luke Beckstrand (USA) and Elizabeth Polsgrove (USA) sprinting to victory. The action continues in the Sprint 5K World Championship, as Richard Hynek (CZE) and Sara Bäckström (SWE) prove that precision and lightning-fast pace are the keys to short-course domination.
