The Life Time Miami Marathon is a winter road marathon in downtown Miami, run on a Sunday in late January or early February alongside a half marathon, with a 5K on the Saturday of race weekend. It is produced by Life Time, and the first edition was in 2003. The marathon starts at 601 Biscayne Boulevard in front of the Kaseya Center, home of the Miami Heat, and heads north before turning onto the MacArthur Causeway, which crosses Biscayne Bay to Miami Beach. After running through Miami Beach, runners return to the mainland over the Venetian Causeway between miles 8 and 11. The half marathon shares about 12.9 miles of the route with the full course; the marathon continues through Brickell and Coconut Grove and crosses the South Miami Avenue bridge near miles 13.2 and 25.5. The finish is on Biscayne Boulevard beside Bayfront Park, four blocks south of the start. The organiser calls it an almost all-flat, single-loop, Boston-qualifying course, with the bridges the only slight inclines. The time limit is 7 hours after the last corral starts, and marathoners must reach the 12.8-mile mark within 3.5 hours to continue.

The Race
Miami
The Miami Marathon has been run since 2003 and takes place in January or early February, when the rest of the country is still in winter. The course crosses the MacArthur Causeway to Miami Beach and returns by the Venetian Causeway. By its 23rd edition, in 2025, the race weekend drew almost 18,500 runners.
On 25 January 2026 Dominic Ondoro of Kenya won the men's marathon in 2:17:47, and Christina Welsh of St. Petersburg, Florida, won the women's race in 2:42:14. The winners all mentioned Miami's humidity. Ondoro was affected by winter storms that left his coach stuck in Dallas, unable to travel to the race.
