Less than a week after he took apart the world indoor 3000m record in New York, USA's Grant Fisher added another world indoor record* to his tally, this time over 5000m at the BU David Hemery Valentine International in Boston on Friday (14).
The double Olympic bronze medallist dropped Jimmy Gressier just after the half way point and continued to extend his lead throughout the second half. After passing 3000m in 7:39.16 - a comfortable 16 seconds outside the world indoor record of 7:22.91 he clocked last Saturday - Fisher continued to churn out sub-31-second laps.
After covering the final 400m in 59.36 seconds, Fisher charged through the line in 12:44.09, a five-second improvement on the previous world indoor record of 12:49.60 set by Kenenisa Bekele in 2004.
Gressier held on for second place in 12:54.92, a European indoor record and outright French record.
Elsewhere in Boston, Tinoda Matsatsa won the men's 800m in 1:45.21 ahead of Ireland's Cian McPhillips (1:45.33), PBs for both.
There were PBs galore in the men's 3000m too, won by France's Romain Legendre in 7:36.28 ahead of India's Gulveer Singh, who set a national indoor record of 7:38.26.
