Cool start, mild finish

Runners will face a temperature range from 45°F at the start to 54°F by finish, with humidity at 66%. A light tailwind will aid runners in the first two miles and again from miles 6-7, but headwinds will challenge them at mile 5 and throughout the later stages. Runners should consider adjusting their pacing strategy, particularly in the headwind sections, and stay hydrated as conditions may feel cooler with the wind.

Race Info

The White River Marathon is held each November in Cotter, Arkansas, with a half marathon and 5K the same morning. All races start at Cotter Schools, drop downhill for the first mile and follow the White River to the finish at Big Spring Park, so the start and finish are in different places; the marathon runs the river out and back twice. The last two miles are on a compacted gravel path and the rest is asphalt. The course is USATF-certified, has a net loss in elevation and is a Boston qualifier; the marathon record is 2:29:34 by Ridley Holmes in 2020.
