About this Race

The Indianapolis Monumental Marathon is one of the fastest marathons in the United States, a flat course through the Indiana capital that has become a magnet for personal-best and Boston-qualifying attempts. The smooth, level roads and gentle layout put the entire emphasis on fitness and even pacing, with no meaningful climb to manage. Held in November, it delivers crisp, cool late-autumn conditions ideal for hard racing. The crowds are friendly and the organization sharp and runner-focused. It suits the dedicated PB chaser who wants a genuinely fast course and reliable cool weather late in the season.

Course Insight

Seattle is a rolling late-November marathon along Lake Washington, with hills, bridge crossings and a strong chance of rain to contend with. Pace the climbs by effort and embrace the cool, damp air as a racing aid even when it dampens the views. The undulation never lets you fully settle. Lake and bridge sections are exposed. Run it as a strength effort and the rollers stay an ally.

Pro tip: Pace the rolling hills and bridges by effort and embrace the cool, damp November air as your ally.

Race History

The Seattle Marathon was first held in 1970 and grew into a hilly, frequently wet late-year tour along Lake Washington with mountain views. Its undulating terrain and cold, damp conditions made it one of the tougher Northwest races. From its founding it became the region's established marathon. Held near year's end, it draws hardy runners to the Washington city.
