About this race
's-Gravenvoeren, in Belgium’s Voerstreek region, hosts the Bear Trail & Grizzly 100, with trail races in October across hilly terrain. The series offers seven distances, from around 17km to the full 100km Grizzly 100, suitable for both new trail runners and experienced ultra runners.
The 100km Grizzly 100 features 2,827 metres of climbing. Its course departs the Voerstreek, proceeds to the Drielandenpunt, loops through the Preuswald, and returns to 's-Gravenvoeren. For those seeking a long ultra without the full 100km, the 85km option is available, alongside 60km, 40km, 31km, 23km, and 17km races. The 100km race has sold out in advance for the last two years, indicating its popularity.
