Bert Timmer Memorial Loop

Horsterpark in Duiven becomes the running center for De Liemers on a Sunday in September for the Bert Timmer Memorial Loop. This is a recreational race day offering 10 km and 5 km options. Additionally, there is a 1 km run for children aged 5 to 12 and a 500 m run for children aged 4 to 6. The 10 km begins in the morning, followed by the youngest children's race shortly after, and the 5 km concludes the events. This schedule accommodates both regular runners and families. The races take place within Horsterpark, avoiding a point-to-point course. The distances are suitable for beginners and young children, while still providing a challenging 10 km for experienced runners. Loopgroep FROS, which stands for Free Running On Sunday, has organized this event annually since 2013. It honors Bert Timmer, a dedicated runner who passed away prematurely. FROS is a local running club that organizes runs on most days. The event is affiliated with the Atletiekunie. Participant entry is limited to 1,000, same-day registration is available, and prizes are given based on age categories.
