👍 Run Pick of the Month: Zion Half Marathon
📍 Squamish - Saturday February 27, 2027
😄 Why We Like This Run
✅ Breathtaking national park views
✅ Smooth, gentle route
✅ An unforgettable atmosphere
Lace up for 13.1 miles through the heart of Utah's red rock country. Starting on Kolob Terrace Road in Virgin, Utah, this gently rolling, point-to-point course follows the Virgin River, just two major turns stand between you and the finish, as towering sandstone walls and endless desert views build with every mile.
It's bold. It's beautiful. It's unforgettable. And it ends right where the adventure should: at Cable Mountain Lodge in Springdale, staring at the South Entrance of Zion National Park. Beat the 10/31 price increase!
