Nedd Brockmann, a 25-year-old Australian running legend, completed an extraordinary 1,600-kilometre charity run, raising over $2.6 million for Australians experiencing homelessness.

The grueling challenge took place over 12 and a half days at Sydney Olympic Park, where Brockmann aimed to break the world record of 1,600 kilometres in 10 days.

He also dealt with adverse weather conditions, including a thunderstorm, which added to the challenge.

During the run, he averaged an impressive 128 kilometres per day, even completing a 26-hour stretch without sleep.

Despite facing significant injuries, including severe shin and knee pain that required injections for swelling, Brockmann persevered to support his charity efforts.

By day 10, his running had deteriorated to a 'limp and a brisk walk' due to the pain, yet he continued to push through.

Upon completing his final lap just after 6 a.m. on Wednesday, Brockmann was visibly emotional, crying and embracing his parents, Kylie and Ian.

The event was live-streamed on TikTok, attracting over 4.7 million views worldwide and drawing around 2,000 spectators for the final night.

Celebrity support came from figures like Olympian Jess Fox and comedian Hamish Blake, who praised his determination and selflessness.

Although his time fell short of the world record set by Yiannis Kourous in 1988, Brockmann's achievement was celebrated as inspirational by many.

Corrina Black, vice president of the Australian Ultra and Trail Runners Association, highlighted Brockmann's run as an inclusive and motivational feat for the ultra-running community.

This latest effort follows Brockmann's previous achievement in 2022, where he raised $1.85 million for We Are Mobilise by running 4,000 kilometres across Australia.
