The 2021 Arkansas 20K will start and end at the River Center in Benton. All turns are marked with large signs with arrows. The race will be chip timed. The course will remain open until 10:00. Temperatures can range from the mid-50s to the mid- 80s. Humidity can sometimes be high. The 20K is an excellent test/training run for a fall marathon as well as a challenging race in its own right.
