MIAMI (CBSMiami) – The 2020 FITBIT Miami Marathon returns to South Florida and participants are preparing themselves to run like there is no tomorrow.

With over 25,000 participants from all over the world, they can’t wait to make it out on the track.

The marathon will start at the American Airlines Arena, then participants part over the MacArthur Causeway to the scenic beaches, through the art district and back around through Coconut Grove.

For those driving, it means lane closures, heavy traffic and finding another route to your destination.

Streets closures will commence at 5 a.m. and streets are expected to reopen by 2 p.m.

Here is the information on the road closures for this weekend’s Fitbit Miami Marathon:
