River Valley Run Half Marathon, 10K & 5K

Saturday, November 6, 2021 • Fort Smith, AR • Course Map

Note: A virtual option is available for this event. Registration details are included below.

Around 300 runners cross the finish line in all races combined each year at the annual fall running of Fort Smith’s River Valley Run Half Marathon, Relay, 10K & 5K, which takes participants on an out-and-back loop course just to the southeast of downtown through historic Fort Chaffee.

The fort served as a military base dating back to the early 1940s and was the site of Elvis Presley’s induction into the army in 1958, and later served as the filming location for movies such as Biloxi Blues, A Soldier’s Story and The Tuskegee Airmen.

Sponsored by locally based Arkansas Fellowship of Christian Athletes organization, the race marks its 12th annual running in 2019, and features its starting and finish line in Ben Geren Park, just outside Fort Chaffee.

From there, runners follow a counter-clockwise loop route that takes them out along Wells Lake Road, Custer Boulevard, Taylor Avenue and then back around toward the start along Fort Smith Boulevard.

The race is run entirely on paved surfaces and takes the field through a combination of forest lands, base buildings and structures, and wide-open fields.

Though the course has a few flat stretches, it also features some significant hills, particularly between the start and the second mile marker, which runners will repeat in the race’s second loop.

    Is this for runners only or can you walk the 5K or 10K?

    I am registering for the half marathon. The webpage here says $50 until October 30…but it keeps trying to charge me $60. Is it $50 or $60?
