Kenya's men matched the achievements of the women's 4x1500 metres quartet as they claimed a new world record at the IAAF World Relays in Nassau, the Bahamas, on Sunday.
The Kenya team of Collins Cheboi, Silas Kiplagat, James Kiplagat Magut and Aspel Kiprop crossed the line in a time of 14 minutes 22.22 seconds, more than 17 seconds clear of the United States in second, while Ethiopia finished third with a national record.
It capped a meeting where the records had tumbled after Jamaica's 4x200 metres men's quartet broke a 20-year-old world record on Saturday.
Nickel Ashmeade, Warren Weir, Jermaine Brown and 2011 world 100m champion Yohan Blake combined to post a time of 1 minute 18.63 seconds to eclipse the 1 min 18.68 secs mark set by an all-US quartet in 1994.
St Kitts and Nevis finished second in a national record time of 1min 20.51secs, while France took third and established a new European record of 1:20.66.
Meanwhile, another world record also fell in dramatic style as Kenya's women's 4x1500m quartet improved the previous mark by more than half a minute.
The world best of 17:05.72, which was set by another Kenyan team in Nairobi last month, was cut to 16 mins 33.58 secs by Mercy Cherono, Faith Kipyegon, Irene Jelagat and Hellen Obir.
Cherono opened with a leg of 4 m 07.4 s, leading at the handover, Kipyegon followed with 4:08.5, Jalegat ran a leg of 4:10.8 with Obiri bringing Kenya home with 4:06.9.
