Experience the magic of Mission Trails at dusk with the highly anticipated 2nd Annual Mission Trails Twilight Runs, scheduled for May 22, 2027. This unique trail running event offers participants an unforgettable adventure through one of San Diego's most iconic parks. The race features two challenging courses: a 50K and a 25K, both starting in the afternoon to ensure runners get their fill of spectacular sunset views as they ascend North and South Fortuna Mountains. As daylight fades into twilight, trail runners will navigate steep climbs, sweeping vistas, and rocky descents under the glow of headlamps. The event is designed for those who want to push their limits while immersing themselves in the surreal beauty of Mission Trails at nightfall. The 50K course offers a full day's adventure with its demanding terrain and stunning views, culminating in an epic twilight finish. Meanwhile, the 25K provides a more manageable yet equally rewarding experience for runners looking to explore this dramatic landscape. Safety is paramount during these nighttime runs, with strict cutoff times ensuring all participants remain on schedule throughout the course. Aid stations are strategically placed along both routes to provide essential support and hydration as you traverse through rugged trails that wind around East Fortuna Staging Area. Registration opens at 1:00 PM on race day, allowing runners ample time for final preparations before setting out into the wilderness. The event concludes with an awards ceremony celebrating top finishers and a sense of camaraderie among all participants who have shared in this extraordinary evening adventure. Join us as we celebrate trail running under starlit skies at Mission Trails—where every step is taken amidst breathtaking beauty that few get to witness firsthand.
