Arkansas 20K

Arkansas 20K takes place in Benton, in Saline County, Arkansas, on October 24, 2026 at 8:00 a.m. The single distance is 20 kilometers, 12.4 miles, and the race starts and finishes at the River Center. The course is well marked and chip-timed, so the result you get is an accurate one.

A 20K is an underrated distance: only about eight-tenths of a half marathon, but long enough that you cannot bluff your way through it on 5K fitness. Pace it like a half rather than a 10K, hold something back until the eight-mile mark, and practice drinking on the move beforehand. Ten to twelve weeks with a long run building toward 10 miles is a comfortable buildup, and finishing one is a strong indicator that you are ready to take on 13.1.
