The Lost Boys 50 Mile / 55 Kilometer Trail Run is a POINT-TO-POINT course that starts in the Anza-Borrego Desert State Park at an elevation of about 1,000 feet. The course heads west over the mountains topping off at Cuyamaca Peak at 6,512 feet and finishes at Cuyamaca Lake, 40 miles east of San Diego. This is a beautiful but extremely challenging run featuring 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. There are approximately 28 miles of trails, 4 miles of desert washes without roads or trails and 18 miles of jeep roads with almost 9000' of climb, 6100' of descent. Well equipped aid stations are spaced 4 to 8 miles apart.
