San Francisco, CA (AHN)-A 7-year-old Arizona boy completed an estimated 1.4-mile swim from Alcatraz Island to San Francisco's Aquatic Park early Monday.

Braxton Bilbrey, who was greeted at the finish by reporters, photographers and well-wishers, was joined by his coach and two other adults in the chilly waters of San Francisco Bay.

Braxton's mother, Stacey Bilbrey originally wasn't sold on the idea of her son swimming from Alcatraz, but she accepted it once he proved he was dedicated to his goal, saying, "For a 7-year-old to be that motivated and stick with a goal that long is amazing."

According to the report, the second-grader from Glendale, Ariz., got the idea when he saw a magazine story about a 9-year-old boy who made the swim. Johnny Wilson, a fourth grader from Hillsborough completed the swim in 53- degree waters last October.

Braxton, who has completed several short-scale youth triathlons asked his swim coach if he could do it.

His coach, Joe Zemaitis says, "If you were to ask me if a 7-year-old is old enough to do it, I'd say maybe one out of 10 million...But he's that one."

When asked what he wanted to do next, Braxton said he hoped to swim the English Channel.
