The concept of GBC500 and 250

The idea behind the challenge is to showcase the Eastern Townships region on some of the most beautiful and least-known roads in the world. Are you daring enough to line up at the start of the Gravel Bikepacking Challenge? Come and explore the hidden treasures of the Eastern Townships region, its unusual gravel roads, breathtaking scenery, charming villages and exceptional local produce.

Whether your goal is to beat the record over the 500-kilometre distance, or to exceed your limits for 250 kilometers, the GBC promises to be a rewarding adventure where the spirit of mutual aid and the passion for cycling meet.

How it works

A few weeks before departure, we will send you the route in digital format. The start is in time trial format. Along the way, you will have mandatory checkpoints in unexpected places of exceptional beauty. You will have the opportunity to discover several shops and local products to taste on site. The route on the most beautiful roads in the Eastern Townships is 75% on dirt roads and gravel tracks, with a few sections on paved country roads (15%). The difficulty level of your challenge will depend on the choices you have to make when registering:

Some will be looking to set a personal record, while others will take up to 4 days to complete this cycling challenge. But no matter which category joins you, know that the Gravel Bikepacking Challenge will make you live an extraordinary human and sporting adventure, and this, in one of the most beautiful regions of Quebec.

A video... what better way to get started!


As in previous years, you must choose your distance (250 km or 500 km) and your category (solo or duo). You always have the choice of doing it on an electric-assist bike or a traditional bike. Here’s what’s new for 2024

  • You have 4 days, or around 60 hours, to complete the challenge, from Saturday June 29 to July 2.
  • Starting Saturday June 29 at 6am, you can ride until midnight maximum, then dark zone compulsory until Sunday 6am.
  • Sunday June 30: course opens at 6am until midnight. Dark zone compulsory until 6am the following day.
  • Official opening times for Monday July 1 and Tuesday July 2 are 6am to 10pm. Dark Zone from 10pm to 6am compulsory.
  • By choosing the assisted category, you can have an external support team at meeting points determined by the organization (4 for the 500km and 2 for the 250KM). Assistants must follow a road book to reach the Pit Stops.
  • If you choose the unassisted category,you ride autonomously from start to finish, withno external assistance planned.
