NN Dam tot Damloop 2026

The NN Dam tot Damloop is a 10 English mile race starting in Amsterdam and finishing in Zaandam. Its point-to-point course offers a straightforward premise: participants depart one city, traverse the IJtunnel, and conclude in another. The IJtunnel section is a memorable part of the course, taking runners beneath the water early on. The event also attracts corporate teams through one of the world's largest Business Runs, blending individual participants, workplace teams, and a large audience focused on the event itself rather than solely on fast finishing times.
