Old Mammoth Road, next to the Sierra Nevada Resort and Spa
After taking a shuttle to the starting line, runners will line up for the race start at Horseshoe Lake, and spend the first mile heading towards Lake Mary. Around the first mile marker, runners will begin to go counterclockwise around the lake for the next two miles, running through an area popular for hiking, fishing and camping.
Once they make it past the third mile marker, runners begin a descent of almost 1,000 feet over the next three miles, making their way along Lake Mary Road and towards the town of Mammoth Lakes. Just past mile marker 5, runners will begin to encounter more signs of life as they reach the outskirts of town.
Past mile marker 6, the course makes a sharp right turn onto Minaret Road. Runners will continue along until Minaret Road intersects with Meridian Boulevard. The next couple of miles runners will encounter a series of turns and switchbacks along a bike path as they make their way towards Waterford Avenue and mile marker 9.
Once reaching Old Mammoth Road, the course heads east for a few miles traversing both roads and bike trails. At just past the mile 10 marker, runners will begin to head out away from the main roads for approximately a mile and a half. Once they near 11.5 miles, the course will begin to loop back west and runners will cross over Meridian Boulevard.
The final mile takes runners back into town until the path intersects with Sierra Park Road where the course takes a sharp left. A right on Tavern Road and a left on Old Mammoth Road will bring runners to the finish line.
