Don your black tie best, Forbes is hosting a gala ball to celebrate and support Nedd Brockmann.

The Bedgerabong-born Brockmann has already raised $2.5 million to help the homeless by running across Australia, now he's planning to cover 1000 miles in 10 days for the cause.

And as he launches his world-record attempt at Sydney Olympic Park, we're being invited to support the cause at the Forbes Gala Ball at Town Hall.

Tickets are on sale now, $150 for a spectacular night with all profit to go to homelessness charity We Are Mobilise.

It's a night to celebrate the incredible achievements of someone from our community, says Sam Mackay, who is one of a group of locals organising the ball.

While Nedd pounds the pavement, it will be an opportunity to hear from the founder and CEO of Mobilise, Noah Yang.

September will mark two years since Nedd gained the attention of the world by running across Australia - from Cottesloe Beach in the West to Bondi Beach in the East - covering almost 4000km in 46 days.

He raised $2.5 million for the charity Mobilise to connect with and support people experiencing homelessness.

On October 3, Nedd will launch his next effort - to cover 1000 miles in 10 days.

That's 1610km and the current world record, set by Yiannos Kouros in 1988, stands at 10 days 10 hours 30 minutes and 36 seconds.

To do this, Brockmann's planning to run 403 laps of the 400m Sydney Olympic Park track a day, which could take anywhere from 15 hours to 19 hours a day.

All profits from the Ball will be donated to the cause, with early bird tickets sold out and general release tickets now on sale online through 123tix.com.au

Be greeted with cocktails in the courtyard before moving into the ballroom for a fundraiser auction, delicious canapés from Eat Your Greens, a stocked bar and a chance to dance the night away with the Baker Boys Band.

The tickets will include three drinks, canapes, lucky door prizes and of course the night's insight and entertainment.

"We hope that everyone gets around it and supports it - it is a once-off kind of event and a lot of work has gone in to make it a really special event where we can hopefully raise some money for a worthy cause," Sam said.

Mobilise works with those experiencing homelessness by reaching out to people on the streets through conversations and care packages.

They are pioneering programs to put funding directly into the hands of those experiencing homelessness, offering employment, support networks and direct grants.

Nedd's also put the challenge out to everyone else to set their own "uncomfortable challenge" for 10 days in October.

"Wherever you want - a road, a track, a pool, your loungeroom, your school, your gym, your workplace - you name it!" he said.

"You set the challenge - there's just two requirements, it has to be uncomfortable and you have to do it each day for 10 days straight."
