Tymen van Keulen

Tymen van Keulen is a Dutch runner who turns big, self-set challenges into stories people follow. From 1 to 3 May 2026 he ran Breekpunt: 355 km from the north to the south of the Netherlands, finishing in 67.5 hours and raising money for the Prinses Máxima Centrum, the Dutch children's cancer centre.

Five months later he switched from distance to speed. After a twelve-week build he documented as his Sub 3 Marathon Series, he broke three hours at the TCS Amsterdam Marathon in October 2026. Next on his list: an ultra beyond 355 km.

His content shows the work behind the result: training weeks, race-day nerves and the low points deep into an ultra. Breekpunt became a 23-minute documentary on YouTube, and his strongest reels reach close to 300K views, far beyond his own following. That makes him a fit for running brands and destinations looking for a real challenge story rather than a one-off post.
