Outside of mammoth races like the Army Ten-Miler, Marine Corps Marathon and the Credit Union Cherry Blossom Ten Mile, Thanksgiving is the busiest day of road racing in the D.C. area. Last years, 13 turkey trots totaled 21,214 finishers just in their timed divisions, to say nothing about fun runs, walks and tot trots, many of which these events sport.
This year at least 16 races will kick off around the D.C. area, with another one following a few days later.
