Day-by-day guide to the World Athletics Ultimate Championship

The World Athletics Ultimate Championship, a new event created by World Athletics president Sebastian Coe, takes place in Budapest across Friday, Saturday, and Sunday. The competition features a $10 million prize pot with $150,000 available for each individual champion, and all 381 competing athletes are guaranteed prize money. The format ditches traditional heats-to-finals structures in favor of straight finals, with notable events including the Mixed 4x100m final where Britain, holding the second-fastest season best behind Jamaica, will compete alongside the United States.
