This event, taking participants through rarely-run trails, combines demanding terrain with stunning views and mystical trail features, such as the Maze with its Nautilus centerpiece.

Prepare to embrace the rugged beauty of the Napa Valley Endurance Run, an event that unfolded amidst the breathtaking landscapes of Robert Louis Stevenson State Park in the heart of Calistoga. The race, contrary to its name, was anything but a leisurely stroll; it was a thrilling adventure that would take participants through rarely-run trails, promising a challenge that would test their mettle. This was not a day at the spa; it was an exhilarating and demanding race, destined to be etched in the memory as a bucket-list experience. The event offered three distinct races, each with its own set of challenges and rewards. The 50k race, an ultimate test of endurance, led runners out and along the Palisades, all the way to the pinnacle of Mount St. Helena. Along the way, they would encounter mystical trail features, such as the Maze, with its captivating Nautilus centerpiece. For the 35k runners, the journey would encompass all these remarkable sights, but they would make their turnaround at Highway 29. Meanwhile, the half-marathon runners embarked on one of the most formidable half-marathons in the country, with the promise of an awe-inspiring view from the Palisades Aid Station. And for those tackling the 10k, it was a climb up the Oat Hill Mine Trail to a turnaround point in the burn zone. The Napa Valley Endurance Run was an opportunity to explore new trails, experience unmatched natural beauty, and challenge one’s limits. It was not just a race; it was an adventure through the Palisades, with each course promising stunning views and demanding terrain. To give a glimpse of the excitement and intensity, Penny MacPhail’s review painted a vivid picture. She described the event as “EPIC” and “the mother of all ultra routes.” Her words echoed the sentiments of many participants who found themselves caught up in the sheer thrill of the race. The Napa Valley Endurance Run had captured the hearts of those who ventured to experience its beauty and intensity. The race started and finished at Logvy Park in downtown Calistoga, a fitting base for this epic adventure. Runners would roll and navigate through the Palisades, traversing trails that few had explored before. The race was not for the faint of heart; it was for those who sought to conquer the toughest challenges and push their boundaries. With the Napa Valley Endurance Run, participants didn’t just run a race; they embarked on a remarkable journey through nature’s wonders. The event was a celebration of the indomitable spirit of runners who reveled in the opportunity to test their mettle and be rewarded with awe-inspiring views. It was a race, an adventure, and a memory to cherish, with the promise of stunning trails and the thrill of the unknown.
