Here's every half marathon happening in Florida in March 2026, organized by expected turnout.
AdventHealth Lake Minneola Half Marathon, 10K & 5K
March 22 | Clermont, FL
This is the marquee half marathon of the month. Run along the beautiful Lake Minneola waterfront on the South Lake Trail in Clermont — one of the most scenic race routes in Central Florida. AdventHealth's backing means top-tier organization, solid field support, and excellent post-race perks: live music on the course, a lakeside after-party with a beer garden sponsored by Suncreek Brewery, hot mac 'n' cheese, free race photos, and a beach towel for every half marathoner. If you're only running one race this March, make it this one.
Wellen Park Half Marathon & 5K presented by Hotwire Communications
March 21 | Venice, FL
Now in its 4th year, the Wellen Park Half Marathon has become one of the standout events on the Southwest Florida race calendar. The course starts and finishes in the heart of Downtown Wellen Park — a vibrant, walkable community just outside Venice — and winds through one of the state's newest and fastest-growing neighborhoods. A portion of proceeds benefits Big Brothers Big Sisters of the Suncoast. Walkers, strollers, and leashed dogs are welcome, making this one of the more family-friendly race mornings you'll find. Start time for the half is 7:30 AM.
AdventHealth Silver Springs Half Marathon, 10K & 5K
March 29 | Silver Springs, FL
For runners who prefer trails over pavement, this one is hard to beat. Set entirely within Silver Springs State Park — home to some of the clearest natural springs in the world — the course takes you through shaded hammocks, alongside the legendary Silver River, and past wildlife you won't see anywhere else on a race course. After the finish, your bib doubles as park admission, so stick around for the glass bottom boat tours or rent a kayak and explore the river. A true Florida experience.
Country Music Half Marathon, 5K & 10K
March 14 | Clewiston, FL
This one comes with a festival attached. The Country Music Half Marathon is the running component of the Clewiston Sugar Festival — a multi-day celebration dating back to the 1930s, rooted in the end-of-harvest traditions of the U.S. Sugar Corporation. Running through Clewiston means running through the heart of Florida's sugarcane country, near the shores of Lake Okeechobee. It's a smaller, community-driven event with real local character — the kind of race where the crowd actually knows the runners.

March 1 (all month) | Virtual — Anywhere in Florida

Frequently Asked Questions
What is the weather like in Florida for running a half marathon in March?
March is one of the best months to race in Florida. Temperatures typically range from the low 50s at early morning start times to the mid-70s by late morning. Humidity is lower than the summer months, and you are unlikely to encounter rain on race day. Dress in light, moisture-wicking layers and plan for warming up quickly once the sun rises.
Are these half marathons good for first-time runners?
Yes. All of the in-person half marathons listed here are well-organized events with course support, water stations, and generous time limits. The Wellen Park Half Marathon explicitly welcomes walkers, and the AdventHealth events are known for their beginner-friendly atmosphere. If you have completed your training, any of these races are a great choice for your first 13.1.
How far in advance do I need to register?
Registration for most Florida half marathons opens months in advance and popular events can sell out. If you are targeting a specific race, it is best to register as soon as you decide to run. The Keep on Living virtual series accepts registrations throughout the month.
