Tenbosse, Mountain pass in Brakel, Belgium

Tenbosse is a mountain pass near Brakel in East Flanders that stretches roughly 200 meters through rolling terrain. The road features a steep gradient of around 13 to 14 percent while gaining approximately 27 meters in elevation.

The Tenbossestraat was a narrow footpath with few buildings until it was widened in 1925. It has been recognised as a Tour of Flanders climb only since 1997, after Johan Museeuw had built his first two victories there. Museeuw attacked again on the Tenbosse in 1998, dropping Peter Van Petegem and riding solo to Meerbeke for his third and last Flanders win. The climb was left out after the finish moved to Oudenaarde in 2012 and returned in 2017.

The climb is the Tenbossestraat, a street in Nederbrakel lined with 20th-century terraced houses, widened in 1925 from an earlier narrow footpath. A yellow flag with a black lion is held above the crowd on the left of the road, the emblem of Flanders, and the race passes here before the Muur van Geraardsbergen and the Bosberg.

The climb is the Tenbossestraat, running from the village centre of Nederbrakel in a south-easterly direction, in line with the Stationsstraat, and rising away from the Zwalmbeek valley. It is an asphalt road 450 metres long at an average of 6.9 percent, widened in 1925 and now lined mainly with 20th-century terraced houses. Crowds stand behind metal barriers on both sides during races, so riders keep to the middle of the crowned surface.

The Tenbossestraat was widened in 1925 and is lined mainly with 20th-century terraced houses. The climb measures 450 metres at an average of 6.9 percent, one of the few urban climbs in the Tour of Flanders. It also features in the LF Vlaanderenroute and LF Heuvelroute recreational routes.
