Historical Overview

Grinduro was first held in 2015 in Quincy, California, and was created by Giro Sport Design in collaboration with Sierra Buttes Trail Stewardship. The event aimed to blend the best elements of mountain biking and gravel racing, creating a race that is both demanding and fun. Since its inception, Grinduro has expanded globally, with events now held in various locations around the world, including Scotland, Japan, and Canada.

The Race Format

Grinduro’s unique format sets it apart from traditional races. The event typically includes a loop course of around 60-80 miles (100-130 kilometers), featuring a mix of gravel roads, singletrack trails, and paved sections. The race is divided into several timed segments, usually four, that test different aspects of a rider’s skill and endurance. These segments can include climbs, descents, and flat-out speed sections.

Key Components of the Race

Timed Segments:

Unlike traditional races where the total time is the only factor, Grinduro focuses on specific timed segments. Riders’ overall standings are based on their performance in these segments, encouraging strategic riding and pacing.

Untimed Segments:

The sections between timed segments are untimed, allowing riders to regroup, enjoy the scenery, and socialize with fellow participants. This format reduces the overall pressure and makes the race more enjoyable.

Varied Terrain:

The courses are designed to challenge riders with a variety of terrains, from technical singletrack to smooth gravel roads. This diversity tests all-around cycling skills and keeps the race interesting.

Key Challenges

Technical Skills:

The inclusion of singletrack and technical descents requires strong bike-handling skills. Riders must be prepared for a mix of terrain types and conditions.

Endurance and Strategy:

Balancing effort between timed and untimed segments is crucial. Riders need to push hard during the timed segments but conserve energy and recover during the untimed sections.

Equipment Choices:

Choosing the right bike and setup is essential. Most riders opt for gravel bikes with wider tires for added stability and comfort on rough sections.

Community and Culture

Grinduro is not just a race; it’s a celebration of cycling culture. The event includes a festival atmosphere with live music, local food and beer, camping, and various social activities.
