Cobbles challenge

108.07 km 2799m alt. 2,59% avg. 28.1% max. 12 hours

Ride 5 cycling videos within 12 hours to be rewarded with a unique bottle and listed as a Tacx Cobble Challenge hero! You’ll challenge a total distance of 108 km and climb over 60 kilometres, with an average incline of 1.5% and a max. slope of 28,1% on the Bosberg.

What would the start of the cycling season be without cobblestones? That’s why we’ve come up the Cobble Challenge: a selection of the finest cobblestone films available in our software. Like the iconic Muur van Geraardbergen, which was often the decisive climb in the Tour of Flanders. But you can also expect some fierce and impressive rides in the Swiss Alps. What about the Grimsel Pass, a killer climb of a whopping 27 km! Or the Gotthard Pass, an old cobbled climb with a length of nearly 14 km with an average gradient of almost 7%. The icing on the cake is the ruthless Bosberg, the hardest climb in this area of Flanders. Good luck with that!

To complete the challenge you’ll have to finish the following films within 12 hours (not necessarily in this order):

Name Distance (km) Uphill total (km) Avg. incline (%) Altimeters (m)
