The feat took place at the Alfa shopping mall in Riga on September 24 when Edgars Simanovičs broke the record previously held by American Ronnie Delzer at 143.84 kilometers.
The record attempt went according to plan apart from a brief concern when his temperature and heart rate began to increase round the 77 km mark. It was decided that cooler air was required and luckily a fan was procured from a nearby store.
Simanovičs, a Riga municipal police officer, is an experienced ultra-marathon runner.
Confirmation of the Guinness World Record will only come after submitting various documents and video footage of the record attempt.
