Mageean (right) on the way to winning World Junior silver in Moncton
Ciara Mageean is leaning towards opting for the 1500 metres at the Commonwealth Games in New Delhi in October.
The Portaferry athlete is in the middle of a two-week break from athletics after her stunning World Junior Championship silver medal in Canada.
However, the 18-year-old will return to training next week.
"Ciara has qualifying times for both the 800m and 1500m in Delhi but she is leaning towards the 1500m," said Mageean's coach Eamon Christie.
Mageean set new Northern Ireland senior and Irish junior records for the metric mile in the Moncton final with a 4:09.51 which cut almost six seconds off her previous personal best.
"We had a brief conversation about the Commonwealths on the flight home from Canada last week and it looks as though the 1500m is going to be the preferred option," added Christie.
"The 1500m is on first in Delhi with the heats taking place on the Thursday and the final taking place on the Saturday with the 800m first round then taking place on the Sunday.
"Ciara's plan has always been to do only one event in Delhi."
Mageean's main target for next season will be the European Junior Championships where she is likely to go in as favourite after her exploits at world level over the past two seasons.
Last year, the Irish star clinched World Youth Championship 800m silver in Italy before going on to earn World Junior silver last week in Canada.
However, Mageean could also come into consideration for a place in next year's World Championships in Daegu.
The qualifying times for the World Championships in South Korea in late August of next year have yet to be announced but the 1500m mark is likely to be in the region of 4:06.50.
Mageean's personal best is over three seconds outside that mark but few would bet against the county Down youngster continuing to improve her 1500m time next summer.
Coach Christie has been hugely impressed by his athlete's dedication to her sport.
"All her friends have turned 18 over the last year or so and Ciara did as well but she had to miss out on all the birthday parties and the socialising and in fact, doing the things that normal teenagers do.
"She has been absolutely tremendous and is already a role model for other young athletes."
