Women’s multis are combined track & field competitions - most often the heptathlon (7 events) outdoors, and less commonly the decathlon (10 events) or pentathlon (5 events, typically indoors) - where athletes earn points in each discipline across sprints, jumps, throws, and middle-distance runs, with the highest total score determining the winner.
The discipline and training applied by decathletes have always been regarded by me as the ultimate in athletic dedication. Whilst it is of course always a huge honour for any decathlete to achieve the ultimate status of World Champion, I cannot help but regard all those who dedicate themselves to this most gruelling of athletic disciplines as Champions - unknown person
