About this race
The One en Only, a quirky relay marathon, starts fair week. Since 2003, ultra-runners and relay teams have competed in 2 to 3 km laps. Teams often wear costumes matching the edition's theme. Sometimes called the 'Back to the Veenolympics Estavete Marathon', it supports local causes.
