The third annual Ultra Maratona Aquática Ilha do Mel includes 10 km and 20 km marathon swims, an aquathlon, a night run and a stand up paddle race in Brazil’s Paranaguá – Ilha do Mel.

There are tide changes along the way with water but the ocean bottom can be clearly seen throughout the course where escorts by dolphins will likely occur between the 10 km and 18 km mark.

Registration is open until April 7th; visit here.
