The bottom line
A quietly fast race that does not ask for much beyond honest pacing.
Miami Marathon is a strong choice for a PR attempt, and Miami offers very little meaningful elevation. The tradeoff is that nothing about it is extreme in either direction.
Why runners choose this race
A loop course around Miami, FL, with very little meaningful elevation change.
