The Lost Boys Ultra Trial Run - 50 mile is a point-to-point trail ultramarathon which starts on the Desert Floor of the Anza Borrego Desert State Park, 75 miles east of San Diego, heads west over the mountains and finishes in the Cuyamaca Rancho State Park. This beautiful and extremely challenging run features spectacular geography, historical trails, contrasting landscapes and incredible views. The first half courses through desert washes, canyons and mountain valleys including a brief section where runners must climb over some dry rock waterfalls. Ascending out of the desert, the mountainous second half climbs and descends through a lush alpine environment. 

The 50 mile course has approximately 28 miles of trails, 4 miles of desert washes without roads or trails, and 18 miles of jeep roads. With over 9000' of climb and 6100' of descent and an elevation range of 1200' to 6,512'. All but 4 miles of the course is contained within the state parks.
