Portaferry athlete Ciara Mageean finished in 11th place in the Dream Mile at the Bislett Games on Thursday evening in Oslo.
Mageean, one of 14 competitors in the race, completed the one mile run in 4.22.03 minutes, five seconds behind Birke Haylom, who claimed the fastest time.
The 31-year-old finished just behind Josette Andrews, one of three representatives from the USA, who completed the race in 4.21.98 minutes.
Mageean became separated from the main pack of runners on the third lap but recovered extremely well in the final 400m to gain some ground on those in front.
Mageean had recently broken the Irish 800m record and put in a strong performance over 1500m at the Florence Diamond League earlier this month, finishing in 4:00.95 minutes.
Ethiopian runner Haylom also claimed the track record, which had previously held by legendary Irish runner Sonia O’Sullivan.
O’Sullivan claimed the meeting’s best time back in 1994 and held the record for almost thirty years. O’Sullivan ran the record time of 4.17.25 minutes, but Haylom finished in the slightly better time of 4.17.13 minutes.
