A-Cross the 3 (ACT3) is an unsupported bikepacking adventure across 3 countries (Belgium, Germany & Luxemburg). It starts and ends in Eupen (prov. of Liège in Belgium). The total distance to be covered is about 500km with approx. 10,000 meters of elevation gain.
If you are looking for a challenge, try to ride it within 72 hours. Otherwise just ride it and have fun. ACT3 is a pure mountain bike track. So it is not recommended to ride it with a gravel bike. For more info or to register, please go to www.act5.be.
