Ciara Mageean set a new Irish Indoor Mile record of 4:28.31 at the New Balance Indoor Grand Prix in Boston on Saturday night.
Mageean finished sixth with the 2013 World Indoor 800 silver medallist Brenda Martinez seventh and reigning World 3000 metre steeplechase gold medallist Emma Coburn back in tenth place.
The race was won by Canada's Gabriela Stafford in 4 minutes 24.80 seconds.
The time improved on Mageean’s previous Irish Record of 4:28.40 which she set three years ago. It is also well inside the 1500m qualification time (4.36 Mile) needed for the European Indoor Championships which will take place in Glasgow in the first weekend in March.
Earlier in the day, Ireland’s fastest women Phil Healy has got her indoor season off to a great start winning the Vienna International Indoor Meet in 52.31.
This is the fastest time of the year so far by a European and the second fastest in the world.
Lissane De Whitte of Netherlands, European bronze medallist from Berlin 2018, was second in 52.66, with Great Britain’s Eilidh Doyle third in 53.08. Doyle is a bronze World Indoor Medallist from 2018.
