An after-dark trail 10K through disco-lit Sierra forest
Other trail races within 140 miles
An after-dark 10K that kicks off the festival weekend with glowsticks and good vibes. Starting at twilight from the Village Plaza, runners climb through Jeffrey pine forest on the Uptown Trail before a lollipop loop at the top and a cruise back down the Downtown Trail to a finish-line party. Disco lights strung in the trees guide the way, and a fluorescent-themed aid station keeps the energy up. Custom medals, pizza, and Best Day Brewing beer await at the finish.
