The Association of Road Racing Statisticians has released its updated worldwide all-time road race rankings through 2010. The rankings score races by both depth and quality of fields throughout each race's history. Click here to see the complete rankings. Below are a summary of the #1-ranked race at each distance and listings of the top races for each individual distance. Click any image to enlarge. The listings below do not include international championship events held on varying courses in different locations.
*Although both the Tokyo International Marathon and Tokyo International Women's Marathon were held on the same course, the ARRS considers the Tokyo Marathon to be the continuation of the men's race and the Yokohama International Women's Marathon to be the continuation of the women's race.
