How Nairobi’s High Altitude Could Shape the 2029 World Athletics Championships

Nairobi will host the 2029 World Athletics Championships, the first time the competition is held in Africa.

The city was officially confirmed as the 2029 host on Tuesday, making it the highest‑altitude venue ever used for the championships. Nairobi sits at roughly 1,795 metres (5,889 feet) above sea level, a record for the event.

Kenya’s reputation in distance running adds extra significance. The nation is a long‑standing superpower in the sport and sits second on the all‑time World Championships medal table, behind only the United States.

At that altitude the air is thinner, so runners face less aerodynamic drag. Scientists say this can translate into faster race times, but the reduced oxygen also means athletes must acclimatise. Teams are expected to arrive early to adapt to the conditions.

If athletes manage the adaptation period, the combination of Kenya’s home advantage and the altitude‑induced speed boost could produce new world records, turning the 2029 championships into a historic showcase of high‑altitude performance.
