Traffic Impact: 305 Half Marathon & 5K Events

Event Date: Sunday, March 1, 2026

Traffic Advisory

On Sunday, March 1, 2026, the Life Time 305 Half Marathon & 5K events presented by Baptist Health will run through Miami Beach. Both events start and finish on Ocean Drive near 11 Street. A finish line celebration will take place in Lummus Park after the event.


The half marathon begins on Ocean Drive at approximately 6 a.m. The runners will make a 13-mile scenic loop going west on the Julia Tuttle Causeway, south on NE 2 Ave. on the Miami side and come back east on MacArthur Cswy. to Miami Beach. All runners are expected to finish by approximately 10 a.m.


The 5K is solely on Miami Beach. Runners (or walkers) will do a quick loop from Ocean Drive to Dade Blvd. and back. The 5K participants will likely complete their course much earlier than the half marathon runners.


What to Expect

The race will begin at 6:15 a.m. at Ocean Drive between 11 and 12 Streets. Runners then proceed north to go out over the eastbound lanes of the Julia Tuttle Causeway clearing this section by 8:15 a.m. All participants will be off the remaining sections of the course by 10 a.m. for the reopening of the roads, however, most of the roadways will be clear before then due to the rolling reopening procedures. Traffic will be managed by the City of Miami and Miami Beach Police Departments who will assist traffic through intersections in between gaps of runner packs; however, we recommend you plan for some short delays should you have plans between 6 a.m. and 11 a.m. on race day morning.
