IRONMAN 70.3 SUPERFROG serves as a charity fundraising race: $35 of each general entry will be a tax deductible donation to the IRONMAN Foundation. The donation portion of this entry will be used to support military and local charities including the Navy SEAL Foundation.

The original and longest running half-distance race, the SUPERFROG Triathlon was founded in 1979. The challenging course was designed by a group of Navy Seals stationed at the US Navy Seals center in Coronado to both prepare them for the IRONMAN World Championship in Kailua-Kona, Hawaii and to enhance their training.

Coronado island is technically a peninsula across the bay from downtown San Diego. Originally a resort city, Coronado has become an affluent neighborhood that is a popular tourist destination. Its beautiful beach (consistently ranked amongst the top-10 in the United States), high-end resorts, golf course, and spectacular views of the San Diego skyline make it a popular place to visit.

IRONMAN 70.3 SUPERFROG will begin with a two-loop 1.2-mile swim in the open Pacific Ocean. Athletes will then embark on a four-loop, 56-mile bike course that travels along scenic Highway 75. The course is flat and fast and features beautiful ocean views. The two-loop, 13.1-mile run offers mixed terrain, including sand, trails and pavement. The course takes athletes up and down the California coastline and through the Silver Strand Training Complex/Naval Special Warfare Advanced Training Command. An energetic finish line awaits athletes just off of the beach.
