Ratings & Reviews for the Potomac River Run Marathon (November)

5 Stars from 1 Reviews

review of 2014 Potomac River Run Marathon (November).   

5 / 5 Stars


Low key small number of runners. Excellent aid stations with paper cups and knowledgeable crews. Great race for a BQ time. You need to be self-motivated, or have a supporter that doesn't mind driving to access points to support you. I rolled up 10 mins before the start and Park bathroom was heated with a very short line. No chip timing and very beautiful trail on crushed gravel that can be pebbly in places so wear comfortable shoes!

Race Tips

Race was two loops and the second half is uphill so pace accordingly. really helps to have a supporter to drive you to the start. Very picturesque and quiet but open to other users, cyclists, joggers and walkers, who were not a problem, just remember its not your trail!

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

Race director provides great info and details on these points.
