Registration is open for individuals, relay teams and Corporate Challenge teams wishing to participate in the second annual Nautica South Beach Triathlon on April 5. The triathlon, which benefits St. Jude Children’s Research Hospital and is open to athletes of all levels, includes a half-mile ocean swim, 19-mile bike ride and a four-mile run. St. Jude is one of the world’s premier pediatric cancer research centers.

The Corporate Challenge is an opportunity for employees to improve camaraderie and promote a healthier lifestyle while raising funds for the children of St. Jude. Corporate teams vie for the Corporate Cup, which is awarded to the team with the best overall race time.
