About this race
The Zorg en Zekerheid Circuit is a paved road running series held in Leiden, South Holland. Participants can register for the entire circuit rather than individual race days, with 5 km, 10 km, and 15 km distances available.
The process is simple: circuit participants collect their bibs at the information desk on race day, where same-day registration is also managed. The entry form lists short, middle, and long distance categories, along with a short-distance option for ages 12-18. Runners aged 15 and under require parental or guardian consent.
