Saturday, February 22, 2020 • Granite Bay, CA • Course Map
Part of a series of running, cycling and triathlon events staged throughout the year in the Sacramento and Folsom Lake area by Roseville, Calif.-based race management company TBF Racing, the Lost Trail Half Marathon Challenge takes runners and walkers on a looping route through Folsom Lake State Park along the lake’s western shore.
Just over 210 runners and walkers crossed the finish line in the race’s 13.1-mile and 5K events at the 2018 race, 115 of which took part in the half marathon — which, like the 5K, follows an out-and-back course that starts and finishes on the park’s beach overlooking Granite Bay.
From there, runners first head through the paved parking lot and then onto the trails that take them south along the lake’s shoreline, with small hills in the early miles of the race.
It’s the later miles that bring the more challenging hills, as runners will ascend what’s known as Mooney Ridge in the second half of the race, before turning back to head to the beach for the race finish.
The hills don’t last for too long, however — the race organizers describe them as “short but steep,” along with plenty of scenic views of the lake from the hills above.
Runners will start the half marathon at 8:00 AM, while those running or walking (or running and walking) the 5K race will start at 8:05 AM.
