The Gravel Bikepacking Challenge 500 & 250 & 100 KM

Due to a problem with the server where the official GBC500 website is hosted, we’re redirecting the site to this temporary page so that you can get the information you need while we sort out the problem. We apologize for the inconvenience.
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 set a new record over 500 kilometers, push your limits over 250 kilometers or experience your first adventure over 100 kilometers, the GBC promises you an unforgettable experience where mutual aid, surpassing oneself and a passion for cycling come together.
85% on dirt roads and gravel tracks and 15% on asphalt country roads.
Checkpoints in unexpectedly beautiful locations
A few weeks before the start, you’ll receive the route in digital format. The start will be in time-trial mode, and along the way you’ll have to validate compulsory checkpoints, located in places as surprising as they are spectacular.

Some of you asked us if we could reduce the cost of registration, even if it meant no longer including the bike jersey and cotton fleece given out at the event. We’ve listened and adjusted the prices accordingly! For those who still wish to wear the GBC colors, it will be possible to order clothing at a special rate reserved for participants.
For this 2025 edition, we’re expanding the Gravel Bikepacking Challenge adventure with an all-new 100 km format, in addition to the 250 km and 500 km routes! Whether you choose to ride solo or in a duo, on a traditional or electrically-assisted bike, each distance promises a unique experience combining challenge, exploration and discovery.
