Mageean and Coscoran off the pace at Fifth Avenue Mile in New York

After two huge performances over the past two weeks - breaking Sonia O'Sullivan's Irish 1500m record when winning in Brussels and finishing second at the Diamond League final in Zurich - it was clear halfway through Mageean was carrying some fatigue.

After breakthrough performances over 1500m in recent weeks, Irish athletes Ciara Mageean and Andrew Coscoran turned in tired efforts to close their seasons at the Fifth Avenue Mile in New York today, finishing 17th and 16th in their respective races.

Mageean had come in as one of the big contenders for the women's race, with hopes high that she could become the first Irish winner at the event for 27 years.
