All Challenges

800 miles from the Mexican border to Utah through Arizona's full ecological diversity — Sonoran desert, Chiricahua sky islands, the Mogollon Rim, and the Grand Canyon.

535 miles from Denver to Durango across eight mountain ranges, six wilderness areas, and seven national forests. The definitive Colorado sufferfest.

670 miles of gravel and singletrack through Oregon's Cascades, from the Idaho border to the California line. Dense forests, volcanic craters, and genuine wilderness.

One of the highest and most remote bikepacking routes on earth. Chengdu to Lhasa via the southern Sichuan-Tibet Highway on gravel and unmaintained mountain roads. 29 passes above 4,000m.

A 620km loop through the Ore Mountains on the German-Czech border. Dense forest roads, old mining villages, and climbs that never stop for long. Under-the-radar and completely self-sufficient.

A 1,280km loop around Hokkaido's interior on unpaved forest roads (rindo). Brown bear country, onsen towns, and road surfaces that would be illegal in most places.

Spiti sits at 3,800m average elevation in a high-altitude desert valley that gets 170mm of rain per year. The circuit crosses Kunzum La (4,590m) and optional passes above 5,000m on roads that are sometimes roads.

The COBDR crosses Colorado end-to-end on dirt — ghost towns, alpine passes above 13,000ft, and enough sand to make you question your tire choice.

A gravel interpretation of the classic alpine crossing from Lake Geneva to the Côte d'Azur. 720km, 24,800m of climbing, passes that top out above 2,700m, and the satisfaction of arriving in Nice with destroyed legs.

The Tuscany Trail runs 560km on strade bianche (white roads) through the hills of central Italy. It is the race that made Italian gravel famous, and the route is as good as advertised.

The BC Epic 1000 crosses British Columbia from the Alberta border to the Sunshine Coast. 1,130km of logging roads, mountain passes, and the specific joy of descending 2,000m to a ferry dock.

The Serra Gaúcha in southern Brazil is wine country, canyon country, and one of the most underrated gravel destinations in South America. 380km on colonial-era dirt roads through immigrant hill towns and the edge of the Aparados da Serra.
