The bottom line
A quietly fast race that does not ask for much beyond honest pacing.
Last Chance BQ.2 - Grand Rapids is a strong choice for a PR attempt, and Grand Rapids offers very little meaningful elevation. The tradeoff is atmosphere: expect long quiet stretches and few spectators.
A loop course around Grand Rapids, MI, with very little meaningful elevation change.
