Answer
Heptathlon is Thiam's area of expertise. It is a multi-event competition in track and field that combines seven different events: 100-meter hurdles, high jump, shot put, 200-meter dash, long jump, javelin throw, and 800-meter run. Thiam's exceptional athleticism and versatility allow her to excel in this demanding discipline, where athletes must perform at a high level in each individual event to accumulate points and determine the overall winner.
