An annual fixture in this small western Colorado town for more than three decades, the Basalt Half Marathon starts at the Ruedi Reservoir and runs alongside the Frying Pan River in the valley between the mountains here in what is known as the “Heart of the Roaring Fork Valley,” named for the Roaring Fork River, whose waters meet those of the Frying Pan River near the town center. The race finishes in Basalt at Lions Park.
