Mountain Bike Races in the Pacific Northwest

10 upcoming events

The Pacific Northwest is North America's deepest mountain bike scene — and the region's race calendar reflects it. From the loamy steep tech of Bellingham and Squamish-adjacent border events to the volcanic singletrack around Bend and the high alpine of the Olympic Peninsula, this is where the sport's best riders sharpen their skills. We catalog every mountain bike race we know across Washington, Oregon, British Columbia border events, and northern Idaho — XC, enduro, downhill, marathon, and the regional stage races that draw international fields.

Frequently asked

  • When is the best time of year to race mountain bikes in the Pacific Northwest?
    The season runs roughly mid-May through early October. June and September are the sweet spots — drier conditions and stable temperatures. July and August trail dust is real but rideable; spring snowmelt keeps higher-elevation trails (Mount Hood, Olympic Peninsula) closed into June some years.
  • Is the PNW too technical for someone used to flatter trails?
    It can be, but it depends on the race. XC events at Bend's Phil's Trail and Hood River are flowy and approachable. Bellingham, Squamish-adjacent races, and most enduro events are aggressively technical with steep loose chutes, roots, and wet roots in early season. Read course previews and look at recent finish times to gauge difficulty before signing up.
  • Do I need a full-suspension bike for most PNW races?
    For enduro and downhill, yes — non-negotiable. For XC and marathon events, a fast hardtail still wins in the right hands but most riders are happier on a 120–130mm full-sus given the terrain. The smooth fire-road XC courses of the Midwest don't exist out here; even "easier" events have rocky sustained descents.
  • Which PNW races draw the strongest fields?
    Trans-Cascadia (multi-day enduro), the Oregon Enduro Series rounds, Northwest Cup downhills, the Bellingham Traverse, and the High Cascades 100 (Oregon) all attract national and international pros. If you want to ride alongside the best, those are the names to know.
  • How wet should I expect race conditions to be?
    In May or early October, plan for wet — even "dry" weeks leave roots greasy and roll-overs unpredictable. June through mid-September is reliably dry for race weekends, but PNW weather can flip. Pack a vest and pre-ride in conditions before race day so nothing surprises you in the first descent.
