Nemesys Tunnelloop

The Nemesys Tunnelloop is an annual running event organized by A.V. Spirit, taking place in Oud-Beijerland on February 2, 2025. This event serves as an excellent training opportunity for participants preparing for the NN Marathon Rotterdam, offering distances of 5, 10, or 25 km for runners, and 5 or 10 km for walkers.

It promotes not only fitness but also social engagement, encouraging friends, family, and colleagues to join in. A portion of the registration fees supports the Roparun, a charity relay run that raises funds for cancer patients, emphasizing the event's commitment to a good cause.
