January 28, 2018 - Ethiopian athlete Samuel Tefera broke the world U20 indoor 1500m record with a world-leading 3:36.05 time. Tefera was competing in the first indoor race of his burgeoning career. But his youth and relative inexperience proved no barrier as he comfortably beat 2012 world indoor champion and 2015 world bronze medallist Abdalaati Iguider.
The Ethiopian crossed the line in 3:36.05 to take 0.23 off the previous world U20 indoor record set by Belal Mansoor Ali in 2007. Iguider, the 2012 Olympic bronze medallist, finished second in 3:36.87 with fellow Moroccan Brahim Kaazouzi taking third in a PB of 3:37.15.
