On July 4, join us for a special event—the McArthur Multipark Marathon. This course starts at Kimberly Bridge and makes a perimeter loop of the Rez, exiting at Lewisboro Town Park. From there, runers sprint across Route 35 to Old Field Preserve then take a combination of roads to Mountain Lakes Park. You’ll make a loop there then head back past Lake Truesdale to the eastern edge of the Rez to Kimberly Bridge. You’ll have options for starting locations and times:
