Alphonce Simbu made history at the 2025 World Athletics Championships in Tokyo, winning the marathon gold medal in the closest finish ever recorded at a world championship marathon — and delivering Tanzania its first-ever world title.
A Photo Finish After 42.195 km
On 15 September 2025, in brutal heat and humidity, the men’s marathon came down to a track-style sprint. Simbu and Germany’s Amanal Petros surged side by side toward the line, and after more than two hours of racing, the Tanzanian lunged ahead to win by just 0.03 seconds in 2:09:48 — the narrowest margin in championship marathon history. Italy’s Iliass Aouani took bronze.
Patience: The Simbu Signature
The victory was a masterclass in Simbu’s trademark patient racing. While rivals pushed early in the heat, he conserved energy in the lead pack, covered every move, and trusted his finishing strength — a strategy refined over a decade of championship marathons.
A First for Tanzania
The gold was Tanzania’s first world championship title in any athletics event, sparking nationwide celebrations. For Simbu — 5th at the Rio 2016 Olympics and bronze medallist at the London 2017 World Championships — Tokyo was the crowning reward for years of consistency at the highest level.
Why Tokyo 2025 Will Be Remembered
Three hundredths of a second. One nation’s first gold. A marathon decided like a 100m final. Alphonce Simbu’s Tokyo triumph stands as one of the greatest moments in marathon history — and the defining race of his career.
