Muelletlón Puerto de la Cruz is a September aquathlon held by Calle de la Marina in Puerto de la Cruz, on Tenerife’s north coast. The race is a type of triathlon, but the format is simpler: athletes race on foot and in the water, with the harbor-side setting integral to the event’s identity. It is organized by A.D. + KM ORORUN, a local sports club.
The series also lists non-competitive running options of 5 km, 10 km, and 21 km, catering to participants not solely focused on aquathlon results. Puerto de la Cruz provides a compact coastal setting, with the start area linked to the old town’s marina streets instead of an inland athletics venue. The name references “muelle,” the Spanish word for pier or quay, fitting a race centered around the waterfront.
