Salland Zorgverzekeringen & Flynth Diepe Hel Holterbergloop 2026

The Diepe Hel Holterbergloop guides runners and walkers up the Holterberg from Holten, Netherlands. This annual late-October event includes road running, walking, a Kidsrun, a Heroesloop, business categories, and main race distances of 6 km, 10 km, and a half marathon. The official title incorporates sponsors Salland Zorgverzekeringen and Flynth, with the organization affiliated with the Atletiekunie. Saturday evening features a 6 km Nightrun and Nightwalk on an illuminated course; glow-in-the-dark outfits are encouraged. Sunday hosts the 10 km, half marathon, longer walks, and children’s events. The routes traverse the Sallandse Heuvelrug, utilizing rolling terrain, forest, and heathland instead of a flat city course. Thousands participate in the Holterberg challenge, with entries limited to 5,000 and no late registration, maintaining a local, organized atmosphere.
