Wango Tango

IT'S BACK! The annual "WANGO TANGO" endurance race, a loud and rowdy 4-hour ENDURANCE mountain bike race/trail run on the City Lake trail system in Siloam Springs Arkansas!

You read that right, this year the Wango Tango will again include a 5k and 10k trail run on the hidden gem of the Siloam City Lake trails set to take place before the start of the 4-hour mountain bike endurance race. All of this awesomeness is set to take place this year on Saturday, November 15th, 2025!

In a partnership with Siloam Springs Parks & Recreation, the Borderline Ozark Off-Road Cyclists are excited to again bring mountain bike racing and trail running to western Benton County!

Along the same vein as the popular ‘Beast of Burden’ event, the Wango Tango features 4-hours of solo and team relay mountain bike racing as well as trail running on beginner and intermediate trails!

The trail run will start at 11 AM and all runners will be off of the trails before the start of the mountain bike endurance race. To add to the mountain bike challenge, a 3 pm start for the endurance race means the sun will set 2 hours into the mountain bike race and competitors will be racing in the dark to finish.

This will be an electronically timed race.

Mountain Bike Award Categories include Solo Male, Solo Male Junior, Solo Female, Solo Female Junior, 4 Man Relay, 4 Woman Relay, 4 Person Co-Ed (any combination of male and female), 2 Person Male, 2 Person Female, 2 Person Co-Ed (1 male and 1 female), and 4 Person Junior co-ed (Can be any combination of male or female Junior racers aged 13-18), E-Bike solo male, and E-bike solo female. Only class 1 E-bikes will be allowed to compete.

Trail Run Award Categories will include top male and female overall finishers, as well as awards for top age category finishers.

Come smash it out solo or with your best compadres as the Wango Tango caters to all skill levels. The race is spectator friendly and friendly heckling is encouraged.

Registration for the mountain bike endurance race is ONLY $50/racer (Juniors are just $30), $40 for the 10k trail run and $30 for the 5k trail run.

There will be food from the grill, snacks, and water during the event for all participants. Trophies will be awarded 3 deep in every category.

Helmets are required for the mountain bike race, and all mountain bike competitors must have at least one light source to compete (Helmet AND bar lights are recommended).

The Wango Tango is unsanctioned, and all participants must sign a waiver. Under 18 must have a parent or guardians’ signature to compete.

Proceeds from the event benefit the Borderline chapter of the Ozark Off-Road Cyclists and volunteer trail advocacy in Western Benton and Washington Counties.

City Lake is located just north of Siloam Springs, Arkansas. From downtown head north on Mt. Olive Street and then turn right onto Dawn Hill Road. Follow signs for parking.

Only volunteers will be allowed to park at the trailhead/pit area. All participants must park in designated parking areas and either ride to the trailhead/pit area or drop off their equipment before parking. Bike racks will be provided in the pit.

Look for additional details as we get closer to race day and we’ll see you at the Borderline!
