The team at Strambecco rates the Best Mountain Bike events in the Northwest for 2025 based on various factors, including reputation, route quality, location, rider feedback, and the overall uniqueness of the event or race. Spanning the diverse terrains of Oregon, Washington, and Northern California, the Northwest offers a rich tapestry of landscapes that make these events truly exceptional. From the lush agricultural plains and temperate rainforests to the semi-arid deserts, majestic mountain ranges, and expansive canyons (including the deepest in North America), the region is a mountain biker's paradise.

If we had to pick the cream of the crop for the Best Mountain Bike Events in the Northwest for 2025—those you'd classify as bucket list events—we'd recommend the 36th annual Mudslinger XC in April, Ring of Fire in September, and High Cascades 100 in July. These standout events, organized by Mudslinger Events, are part of the prestigious Oregon XC Series, comprising several races that showcase Oregon's finest MTB routes.

Mudslinger XC

The 36th annual Mudslinger XC in April is one of the Northwest’s oldest and most beloved mountain bike races. As the second event in the annual Oregon XC Series, the Mudslinger XC has been a staple in the mountain biking calendar since 1987. Set in Blodgett, Oregon, this race brings back a vintage atmosphere to mountain biking and cross-country racing. Riders from all over Oregon and the greater Northwest gather for this early-season event, which offers a challenging course featuring old-school logging roads and single tracks. The event’s unique character and deep roots in the community make it a must-ride for any serious mountain biker.

Ring of Fire

In September, the Ring of Fire offers mountain bike enthusiasts a thrilling end to the MTB season. Held near Bend, Oregon, this race is part of the National Ultra Endurance Race Series and features a demanding 53-mile course with 5,000 feet of climbing. The name "Ring of Fire" refers to the Cascade Mountains and the volcanoes that are part of the 25,000-mile volcanic region of the Pacific Ocean basin. With stunning singletrack trails and breathtaking views of Mt. Bachelor, this event is a true test of endurance and skill. The strategic placement of aid stations and the community-focused approach to trail maintenance further enhance the experience for participants.

High Cascades 100

The High Cascades 100, held in July, is the pinnacle of endurance mountain bike racing in the Northwest. This 100-mile race near Bend, Oregon, features nearly 10,000 feet of elevation gain and is known for its technically demanding course. The event includes well-stocked aid stations, mechanical support, and a variety of race categories, making it a comprehensive and well-organized challenge for riders. As part of both the Oregon XC Series and the National Ultra Endurance Series, the High Cascades 100 attracts top riders from across the country and is highly regarded for its stunning scenery and rigorous demands.

This series offers a dynamic mix of MTB and gravel events throughout the region, catering to various skill levels and interests.
