A few hours after Christian Coleman ran 6.37 to break the 60m WR, UTEP's Michael Saruni ran 1:14.79 for 600 in Albuquerque to break Cas Loxsom's indoor 600 WR of 1:14.91. Saruni's former UTEP teammate Emmanuel Korir broke the same record on this track last year (1:14.97) before Loxsom broke it later in the season.
Details from his coach Paul Ereng below.
And yes, technically this is a world best, but we consider it a WR. No one has ever run faster in the indoor 600.
