Most people know about the biggest marathons: Boston, New York, London. And other huge races like Atlanta’s Peachtree Road Race. But what about the biggest, most popular half marathons in the U.S. and the world?

Some research I did a few days ago about the fastest and slowest half marathons in the U.S. made me curious to find more statistics on our favorite race distance and the runners who are participating in them.

Running USA has compiled a wealth of numbers on exactly that in its annual Half Marathon Report issued back in April, so I found the nation’s largest half marathon fields by the number of finishers for 2013.

Here’s the list, and bear in mind that some of these races already have surpassed these numbers at their 2014 runnings:

  1. OneAmerica 500 Festival Mini Marathon – 30,059
  2. Nike Women’s Half Marathon San Francisco – 26,406
  3. Walt Disney World Half Marathon – 23,148
  4. Disney Princess Half Marathon – 22,739
  5. NYRR Brooklyn Half Marathon – 21,427
  6. Rock ‘n’ Roll Las Vegas Half Marathon – 20,665
  7. Rock ‘n’ Roll DC Half Marathon – 19,994
  8. Rock ‘n’ Roll Philadelphia Half Marathon – 18,137
  9. Rock ‘n’ Roll San Diego Half Marathon – 18,077
  10. St. Jude Country Music Half Marathon – 18,022
  11. Disneyland Half Marathon – 15,871
  12. ING Miami Half Marathon – 14,939
  13. Surf City USA Half Marathon – 14,792
  14. New York City Half Marathon – 14,535
  15. Nike Women’s Half Marathon DC – 14,478
  16. Rock ‘n’ Roll San Antonio Half Marathon – 14,427
  17. Rock ‘n’ Roll Chicago Half Marathon – 14,038
  18. Pittsburgh Half Marathon – 14,016
  19. P.F. Chang’s Rock ‘n’ Roll Arizona Half Marathon – 13,430
  20. Philadelphia Half Marathon – 12,480
  21. Rock ‘n’ Roll Seattle Half Marathon – 12,445
  22. Disney Wine & Dine Half Marathon – 12,147
  23. Long Beach International City Bank Half Marathon – 12,033
  24. Disney Tinker Bell Half Marathon – 11,948
  25. Cincinnati Flying Pig Half Marathon – 11,925
  26. Kentucky Derby Festival Mini Marathon – 11,485
  27. Rock ‘n’ Roll Savannah Half Marathon – 11,414
  28. Detroit Free Press/Talmer Bank Half Marathon – 11,000
  29. Nationwide Children’s Hospital Columbus Half Marathon – 10,842
  30. Rock ‘n’ Roll Dallas Half Marathon – 10,711

It’s worth noting that 2013’s Nike Women’s Half Marathon in Washington, D.C., was the largest inaugural half marathon ever, and the race was even bigger in 2014 with just over 14,700 finishers.
