10346 Triathlon           Discovered 1992 Apr. 2 by C. S. Shoemaker and D. H. Levy at Palomar.
Since Pam Truty founded the Burn Lake Triathlon in Las Cruces, New Mexico, in 1984, the relay team of Wendee Wallach-Levy, Laura Wright and Barbara Pardo has won medals every year, including 14 golds. Laura has also done more than 30 years volunteer work for the American Red Cross.
