The Ameris Bank Jacksonville Marathon is a road marathon in Jacksonville, Florida, held on a Saturday in December and listed in the race calendar of 1st Place Sports, the Jacksonville running store that runs it. The marathon starts at 7:00 am at The Bolles School on San Jose Boulevard and finishes there, with a loop through the Beauclerc and Mandarin neighbourhoods in between. A half marathon and a 5K are held on the same day. The marathon and half marathon courses are USATF-certified, and the organisers call it the fastest marathon course in the South. The time limit is six hours, and the marathon is Boston Marathon qualifying. The first Jacksonville Marathon was run on 7 January 1984, and the 2024 race was the 41st annual one. In 2024 both winners were running their first marathon, with Michael Warner taking the men's title in 2:35:19.
