Sifan Hassan will put her legendary range to the test when she makes her marathon debut in London on April 23rd. Hassan has won global titles in the 1500m, 5000m and 10,000m and has already proven her world class ability in the distances from the 800m (1:56) to the half marathon (1:05:15).

At the Tokyo Olympics, she attempted a historic 1500m, 5000m, and 10,000m triple and came away with gold medals in the 5000m and 10,000m and a bronze medal in the 1500m. In 2019, Hassan became the first athlete in history to win the 1500m and 10,000m at the same World Athletics Championships.

“Excited to announce I will test myself over the marathon distance at the @londonmarathon this year!” Hassan posted on Instagram.

“It doesn't mean I move to the road, I will continue my career on the track. However, I want to see what I can do on the marathon distance, to make future decisions. We'll see if I will finish the distance or if the distance will finish me.”

But the London Marathon will be a new challenge for Hassan, both in terms of the distance and the quality of competitors that will share the start line with her. The field includes five women who have run under 2:18 and five other who have bettered 2:19.
