The bottom line
A quietly fast race that does not ask for much beyond honest pacing.
Rehoboth Seashore Marathon and Half Marathon is a strong choice for a PR attempt, and Rehoboth Beach offers very little meaningful elevation. The tradeoff is that nothing about it is extreme in either direction.
A out-and-back course around Rehoboth Beach, DE, with very little meaningful elevation change.
