Career
Her career coincided with the development of women"s running in the United States and she was at the forefront of distance running in the mid-1970s. Her personal best time of 2:37:57, set at the 1977 Nike Over-the-counter Marathon, was an American record for the distance and made her the fourth best runner worldwide that year. She ceased competing around 1980, although she made an unsuccessful attempt at the 1984 Olympic Marathon Trials.
During her time there she received AIAW honours in track and field and cross country, as well as earning Academic All-America honours for her studies as a student-athlete.
Running in her first race abroad, she took second place at the Waldniel Women"s Marathon in West Germany behind Christa Vahlensieck. This was the fastest run by an American woman that year.
Merritt broke the American record for the distance at the 1977 Nike Over-the-counter Marathon in Eugene, Oregon, winning the women"s race with a time of 2:37:57. She returned to the New York Marathon but finished as the runner-up, beaten to the finish by Michiko Gorman.
The 1978 season was her busiest in terms of marathons: she opened her year at the Boston Marathon, just missing the podium with a fourth place finish, and ran at the inaugural Cleveland Marathon the following month, where she finished second after Jacqueline Hansen.
Her final year of competition at the top level was in 1979. The Avon Waldniel Marathon in September was a more successful outing, as she was the runner-up to England"s Joyce Smith and completed the distance in 2:39:43 – the second fastest of her career. She made a brief return at the United States of America Olympic Marathon Trials for the 1984 Los Angeles Olympics, but her run of 2:43:31 was only enough for 53rd place.
