Few spots remain in the 305K!!

The Ultimate Miami Experience!

The new 305 Half Marathon & 5K (March 3, 2019) is all about local vibes, attracting visitors from all over the world and those who are fired up to call Miami their home. Once known as the 13.1 Miami Beach & 5K, this ultimate Miami experience is a cultural gem that will have you running like you live here. Count on a fast and coastal course with a fresh and vibrant Miami soul. It’s how we do it in the 305!

Claim Your 305 Three-peat!

Athletes earned the ‘3’ medal when they crossed the finish line in 2018.  Add the ‘0’ in 2019 and ‘5’ in 2020 to complete your 305 three-peat!

Missed the 2018 event? You will be able to purchase the ‘3’ medal from the 2018 event during registration for the 2019 event to accompany the ‘0’ medal you’ll earn this year as the next piece in your 305 three-peat.

*Registration for the 2020 event may be pre-purchased within the 2019 registration flow. No additional steps necessary to receive your medals each year besides registering for the each event and crossing the finish line each year. 

Not going for the 305 three-peat? Still receive an awesome stand-alone medal when you cross the finish line on March 3!

This year’s medal will feature a double-sided design – one side catering to our 305 three-peat participants, the other for those only racing in 2019.

Plus, the neck ribbons will match up to each other to create an image of one of our iconic bridges! Make sure you bring some friends along to race with you so you can recreate the image pictured right.
