How it All Started

The Florida Keys is a fantastic location for triathletes and outdoor-lovers alike, as the water is the warmest in the U.S. year-round.  Our Florida Keys Overseas Heritage Trail, that extends the length of the Keys (over 100 miles), is a cyclist's paradise.  And running across islands under palm trees is certainly a beautiful thing...  MaraTri (short for Marathon Triathlon) was founded by two Marathon locals with a passion for family-fun events and endurance sports.  Our first race was simply an intro to triathlon for the local community on the sports of triathlon, but it was a huge success!  Our event continues to grow, each year being bigger and better than the last  Every participant came and left with huge smiles every race.  And we're right there with you cheering you on to be the best you can be!  We are dedicated to making MaraTri one of the best run races anywhere.  Come race through paradise with us!  See you at the starting line!



MaraTri is dedicated to supporting local youth athletics.  All race proceeds will benefit local school athletic programs, and students directly through scholarships.  Please show your support by registering to race, or help volunteer!


We believe that a race is only as strong as its volunteers.  We're looking for energetic, dedicated volunteers to help keep our course safe and fun for all our racers.  Please Contact Us immediately if you are interested so we can put you down on our list of volunteers.  Community service hours can be given for your time volunteering.  Let's make this race awesome together!
