SANTA BARBARA, CA - Since the USATF Road Running Information Center began compiling running data in 1987, we are often asked: "How many marathons are there in the U.S.?" Currently, with the widespread use of the Internet for running calendars and a reasonable stability for most events of the distance, we are much closer to having a complete list of marathons. As a start, there were 348 different U.S. marathons included in the RRIC database and/or found on the top 10 online calendar sites over a 12 month period. If you add an estimated 25 events that are more local and not on a national or regional radar, a reasonable minimum estimate is 375 U.S. marathons.

Another way to approach the marathon count is to examine the certified course list. There was a time in the mid-1990s when the total number of U.S. certified marathon courses was around 650. Now some courses have expired (after a 10 year life) and the current total as of March 7, 2004 was 444 "active" marathon courses. On closer examination, approximately 114 of those were duplicates. Then remove another 15 which are probably no longer used such as "1996 Olympic Marathon" and the canceled "DC Marathon." After adding an estimated 55 for uncertified courses, trail marathons and courses used more than once a year, we get the same estimate of 375.

Due to this revision of event numbers, the historical estimated finisher totals have also been revised as follows:

Year Estimated U.S. Marathon Finisher Total
1976 25,000
1980 120,000
1990 236,000
1995 312,000
1996 340,000
1997 340,000
1998 360,000
1999 374,000
2000 389,000
2001 366,000
2002 388,000
2003 400,000

In the U.S., marathons in 2003 grew by 3% compared to 2002, while outside the U.S., there was another year of solid growth with a 4.9% increase for the same 62 marathons (301,747 finishers in 2002 vs. 316,470 in 2003).

For the first time in history, four marathons - New York City, Chicago, London and Berlin - reported over 30,000 finishers in the same year (2003). The 2003 ING New York City Marathon supplanted the Flora London Marathon as the world's largest with a race record 34,729 finishers and #2 all-time ranking (only the 100th Boston Marathon in 1996 with 35,868 finishers is larger), while the LaSalle Bank Chicago Marathon continued its growth spurt as it also jumped over London for the #2 world-wide position in 2003 with 32,362 finishers. Like 2002, the U.S. again had 7 of the 15 largest marathons in the world.
