After the consolidated success of the Gião Bike Challenge, its “sister event” now arrives: a unique mountain bike endurance experience, with the quality seal and guarantee that only Gião can offer.

🔸 3 hours at sunset, one circuit, you against the clock, and at the end a sunset gathering to socialise with everyone.

The GB3 challenges you to complete as many laps as possible on a closed and technical circuit during 3 intense hours. Whether solo or in teams (depending on the category), your endurance, strategy, and spirit of perseverance will be put to the test.

Ideal both for those just entering the world of mountain biking and for those who already live each race with determination.

🤝 Friendly and competitive atmosphere
In Gião, the true spirit of mountain biking is alive: fair competition, well-designed trails, and a community united by sport and passion for cycling.

🏁 Experienced organisation
The same team that brought you the Gião Bike Challenge, one of the most respected events on the national calendar, now takes you to a new challenge with the same commitment to quality, safety, and excitement you are used to.
