After setting the world record for the 300 metres hurdles during its last year on the official program at age 80, at age 81, Canadian Earl Fee set the still standing world record of 36.95 (+0.0) at the NCCWMA Regional Championships in Mayaguez, Puerto Rico on September 5, 2010.

Almost four years later, Fee also set the M85 record of 42.70 (+0.4) in the same meet, this time being held in San Jose, Costa Rica on August 23, 2014.

The M90 record of 51.31 was set a month earlier by American Ralph Maxwell with the benefit of high altitude in Fort Collins, Colorado, USA at the Rocky Mountain Masters Games.

Australian Marge Allison holds the W70 record of 36.71 (+0.7), set August 12, 2015 in Lyon, France, at the 2015 World Masters Athletics Championships.

American sprinting legend Irene Obera learned hurdles sufficiently to set the W80 record 42.24 (+1.2) on July 20, 2014, at the USATF Masters Championships in Winston-Salem, North Carolina.
