Magnum150 kmchallenge

the magnum 150 is one tough ride

The Magnum 150 is a tough ride. It was going to be the toughest distance before one crazy guy (who shall remain anonymous) pushed to include the 300-km route. The gravel riding through Franciacorta vineyards is stunning, the climbs are tough but rewarding, and the view of Lago d’Iseo is always waiting around the corner.

The Magnum 150 starts at 6am the cut-off time is 12 hours based on a 12.5kmh average speed. Of course, the delicious local food and wine will be there to be enjoyed at the end of this incredible ride.

We also invite your friends and family to join us, and anybody who does not wish to ride will find plenty of things to do at the start/finish line and in the immediate surroundings. You can also make a long weekend out of by adding some relax time along Lago d’Iseo or in Verona and Bergamo.

Nutrition station/checkpoint:

  • Bossico after about 90km
  • Sale Maresino after about 110km

At the nutrition stations you will find rice salad, fruits, cakes, sandwiches and water.


  • Boario Terme ( look for a B&B )
