Haarlem

Haarlem is a compact, flat Dutch city 20km west of Amsterdam where the running and cycling infrastructure is equally relentless. The Teva Halve van Haarlem half-marathon and SportSupport Halve van Haarlem draw serious runners through the city's canal network and surrounding polders; cyclists treat Haarlem as a springboard into the dune routes along the North Sea coast (15–20km west) and south toward the Gooi region's gentle forest roads. The wider network of regional races like the 87e Sloterplasloop and Valouwe Trail means the area supports a strong club running culture across flatter terrain than inland Netherlands.
