The bottom line
A balanced race that suits most goals without specialising in any.
Kentucky Derby Festival Race Weekend is a strong choice for a first marathon, and the course rolls gently without any sustained climbing. The tradeoff is that nothing about it is extreme in either direction.
A loop course around Louisville, KY, with steady rollers that reward even pacing.
