JACKSONVILLE, Fla. -- High levels of algae in the St. Johns river threatened to cancel the event, but ten swimmers took to the St. Johns for a 2-hour swim Saturday.

The swim was designed to encourage preservation of the river, boost the economy along the river and raise money for the Special Olympics.

The Jumping Fish organization was formed to promote athletics on the river, and use of the river and that is what they did Saturday.

Founder Jim Alabiso was among the 10 swimmers that left JU shortly before 10 a.m. accompanied by kayakers, boaters and paddle boarders, headed downtown to the Riverside Arts Market.

With the help of the current, it took just about two hours to get south of the Acosta Bridge and begin arriving at the Riverside Arts Market to the cheers of hundreds along the riverbank.

The event's organizer presented Duval County's Special Olympics swim team $1,000 and Clay County's Special Olympic swim team with $500.
