The 5K is one loop out-and-back along the shore. The 10K is two loops of the same out-and-back course. The 10K has a cutoff of 1 hour and 40 minutes. Wheelchair participants are welcome, but the course includes several tight 180-degree turns that may not suit all wheelchair racers.
Parking is limited on Bay Ridge Ave and Shore Road; public transportation is encouraged. Bib mailing is available for a fee if registered early. Amenities include an informal bag check area, bathrooms a few minutes' walk from the start and finish, hydration at the finish, and refreshments provided by All Round Foods and Waterloo Sparkling Water.
