TOKYO — After winning a gold medal at the Summer Olympics here, United States wrestler Tamyra Mensah-Stock had big plans for the bonus money that comes with it: buying her mother a $30,000 food truck.

Tamerlan Bashaev, 25, a Russian judoka who claimed a bronze medal, wants to use his money to get married and go on a honeymoon. Andrea Proske, a rower who helped Canada win its first gold medal in the women’s eight since 1992, can’t wait to take her mother on vacation to London.
