The Boels Rental Run is an annual road race in Dordrecht, organized by Atletiekvereniging FORTIUS. It offers runners seven distances, from short youth races to a half marathon: 400, 600, and 800 meters for children on the FORTIUS track, plus road races of 5 km, 10 km, and 21.1 km. The half marathon is certified by the Atletiekunie and counts as the third event in the StardGRL Loopcircuit. The race is limited to 1,400 participants, and registration can close before race day.
The road courses follow paved streets around Dordrecht, with the longer routes passing the Wantij and crossing the Hollandse Biesbosch. Participants range from young children in the free track races to adult half-marathon runners, with minimum ages specified for the 5 km, 10 km, and half marathon. This is a long-standing local race, with over forty editions completed, and recent events have seen record numbers of participants. The half marathon is competitive enough for course records; Saskia Kersbergen set the women's mark at 1:18:14. Practical services like a bag drop and a massage team contribute to its club-run atmosphere, catering to regular runners and fast competitors alike.
