“DirtyClean挑战”已举办至第八届，这是一系列原汁原味、震撼且极具挑战性的格兰芬多（Gran Fondo）类型活动。分为一日支援和多日无支援骑行活动。

Now in its 8th year, DirtyClean Challenges are authentic, stunning, and tough gran fondo-type events. They are broken down into single-day supported segment-based races and unsupported ultra events.

快来挑战我们的“徽州500挑战”——全年任意时间，在72小时内完成500公里无支援骑行！

Try The Triple Challenge – Finish 250km, 4000m within 24h.

Try our Huizhou 500 Challenge – Finish 500km, unsupported, within 72 hours at any time of the year!

我们为期一天的“DirtyClean挑战活动”将于2026年秋季再度举办，届时将呈现激动人心、风景如画且极具挑战性的公路骑行活动。车手们将在开阔的道路上通过计时赛段挑战自我，沿途设有补给站提供饮品和装备。每年，一群热情的车友都会重返赛场，不仅为了征服赛道，更是为了交流互动、结交朋友，并共度一个难忘的骑行周末。

Our one-day DirtyClean Challenges, next scheduled for autumn 2026, deliver thrilling, picturesque, and demanding gran fondo races. Riders test themselves on timed segments along open roads, with support stations offering refreshments and gear. Each year, a devoted community returns not only to conquer the course but to connect, forge friendships, and enjoy an unforgettable cycling weekend.
