15-year-old Angel More became the youngest person to clench the California Triple Crown of Marathon Swimming.

She completed a 21.3-mile swim across Lake Tahoe this weekend. Angel entered the lake at about 9 p.m. Friday night and swam through the night and into this morning, finishing at about 12:40 p.m. Saturday. It was a more than 15 hour swim across Lake Tahoe.

She has conquered the other two legs of the CTC of Marathon Swimming, which were the The Santa Barbara Channel, which she completed 12 miles in 7.5 hours, and the Catalina Channel, which she finished 20 miles in 14.5 hours.

While accomplishing this title, Angel was raising funds for Children International, a nonprofit that helps kids around the world that were born into poverty.
