Six-day race, women

What to remember

Six days of running, and one total distance to measure the effort. In 2025, at Vallon Pont d'Arc, Megan Eckert covered 970.685 km and broke the previous women's six-day world record.

Multi-day races sit at the far end of ultrarunning, the family of footraces longer than the 42.195 km of the marathon. They are commonly held as 48 hours, or over 320 km or more, sometimes in stages with breaks for sleep.

The more common distances of the sport give a sense of scale. The shortest common ultra is 50 km, and 160 km is typically the longest course raced in under 24 hours.
