It's a race like no other and it's happening in Brevard County this weekend.
It's the annual Tour de Turtles and two of the competitors are kicked off their journey Sunday morning in Melbourne Beach.
The goal is to see which turtle travels the furthest distance over the next three months.
The two loggerhead sea turtles that were released Sunday will compete against 11 other sea turtles that have already been released from around South Florida and the Caribbean.
Myrtle and Dash are the names of the female Space Coast loggerhead sea turtles this year.
Not a lot is known about their migration and scientists want to know where sea turtles go and why.
After laying their eggs in Brevard County they travel hundreds, if not thousands of miles to feeding areas.
“We’ve learned that of course sea turtles like to return to the beach where they’re from in order to nest, said David Godfrey, Sea Turtle Conservancy Executive Director. “But most importantly, they go to all different kinds of forging grounds in other countries.”
Satellite transmitters are attached to the shells of each turtle so that they can be tracked.
More loggerhead sea turtles nest in Brevard County than anywhere else in the world.
And so far this year, the Sea Turtle Conservancy is pleased with the numbers halfway through the nesting season.
At the Archie Carr National Wildlife Refuge, they've counted 12,932 loggerhead nests, 8,938 green nests, and 57 leatherback nests.
The green turtle nests could break a record this year. To track the turtles competing this year, go to: www.tourdeturtles.org
