Hi Patti, this was the source I used for your marriage date:

The Boston Marathon in April (1980) was Catalano's breakthrough, the race that convinced her she could run with the best. She didn't win it;
she finished second to Gareau--third, if one counts Rosie Ruiz--but
her time (2:35:08) was her best to that date, and it permanently
rearranged her head.
Thirteen days later, on May 4, she won the 15-km. Midland Run in
Far Hills, N.J. over a field that included Gareau and Moller. On
May 17 she married Joe Catalano, her coach, and did two eight-mile
training runs. On May 18 she ran a women's American record for five
miles (26:14) in the National Fire Protection Race on the streets
of Boston. On May 25, in front of a crowd of 70,000 in Wheeling, W.
Va., she set a 20-km. world record (1:08:36.7) on a course that
Bill Rodgers has said is "the toughest 20K course I know of." On
May 31 Catalano finished second behind Waitz, who established a
world record 30:59.8, in the L'eggs Mini Marathon in New York, but
her time (33:03) was at that point her best for 10 km., and she
said, "I wasn't discouraged to see her so far away. I was happy to
see her at all."
In June Catalano set an American record for 15 km. (49:42) in
Oregon's Cascade Run Off, and on Sept. 6, in Montreal, she ran the
second-fastest marathon ever by a woman (2:30:57.1), in the process
beating Gareau, who then had the fourth-best time on record. On
Columbus Day Catalano set an American record for 10 km. (32:24) at
the Bonne Bell race in Boston.
