Background

Over 20,000 participants took part in the 5km, 10km and 21.1km categories on Sunday.

The run started at 4:15am at the F1 Pit Building.

The 2XU Compression Run organisers put up a social media post hours after the event informing the public that a participant had passed away.

Previously, in 2014, a 45-year-old man collapsed during the 2XU Compression Run marathon and died in hospital.

It was the third death in the marathon's history of the event first held in 2002.
