About Pacific Trails 50K

Pacific Trails 50K is the 50.0km trail race at HOKA Pacific Trails California by UTMB 2025 (San Luis Obispo, United States). The race starts on November 22, 2025.

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • 419m descent. Go easy, save your quads.
  • The finish is runnable. Save your legs to run it all the way.
  • Ease into the early runnable section, save your quads on the descents until 22.4km, then run your race pace.
  • Start · 0.0km–2.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.6km–28.7km · Climb of 424m, high point 790m, descent of 419m averaging 7%. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can.
  • Work · 28.7km–34.0km · Plus 1 more descent. This is where the race is built: steady, solid effort.
  • Home · 34.0km–51.5km · 17.6km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
