Men's relay record not ratified by IAAF

LONDON, July 11 (Reuters) The International Association of Athletics Federations (IAAF) has not ratified the 4x400 metres relay indoor world record set by the U S in February.

The time of three minutes 01.96 seconds was not approved because no analysis for the banned substance erythropoietin (EPO) was performed, the IAAF said on its website today.

The quartet of Kerron Clement, Wallace Spearmon, Darold Williamson and Olympic champion Jeremy Wariner ran the time at a meeting in Fayetteville, Arkansas on February 11.

The previous mark of 3:02.83, set by the US in 1999, will remain the world record.
