20 years ago Sonia O'Sullivan broke the 2,000 metre world record at Edinburgh knocking more than three seconds off the record. 

The Cork runner clocked 5 minutes, 25.36 seconds at the TSB Challenge meet, shaving more than 3 seconds off the previous record, set by Maricica Puica from Romania in July 1986.

In second place was Yvonne Murray from Scotland, who also ran under the previous record.
