The first 16 miles of the Lower Potomac River Marathon course are completely flat mostly along the water. There is a 6 miles stretch from miles 16 to approximately 23 that travels inland and has some small gently rolling hills. The course then returns to the coast for a flat finish.
Typical race day weather is cool and this, coupled with the fast course can lead to PRs and Boston Marathon qualifying times.
