The bottom line
A quietly fast race that does not ask for much beyond honest pacing.
White River Marathon is a strong choice for a PR attempt, and Cotter offers very little meaningful elevation. The tradeoff is atmosphere: expect long quiet stretches and few spectators.
A out-and-back course around Cotter, AR, with very little meaningful elevation change.
