Huntsville, located in northern Alabama, provides an appealing backdrop for this September marathon. The city sits in the Tennessee Valley region, known for its moderate climate and natural surroundings.

The Boston or Bust Marathon takes runners across a predominantly flat course with gentle rolling sections that break up the rhythm without presenting serious challenges.
