Tyburski will tackle what he has dubbed the ‘500 man’ – a 10 kilometre swim, 390km cycle and 100km run – and is inviting people to join him on the course.

It will be held at Tyburski’s current home base in England on July 7-8. The swim will be in Shepperton Lake – near the river Thames – while the cycle route is set to take him past Windsor Castle.

“I’ve had the format for the 500 Man in my head ever since I completed my 2000 kilometres in 12 day Ultimate Triathlon from Morocco to Monaco. I wondered what it would be like to run 100 kilometres as part of a triathlon, then I simply worked the other two disciplines distances out from there,” Tyburski said.

“I wanted to create a challenge were people could quite literally join me right in the middle of it all, and see, feel, and witness it with their own eyes.”

The 500 man will not just be about Tyburski pushing himself to his limits – he will also be raising money and awarness for The 401 Foundation after forming a friendship with the charity’s founder Ben Smith.

“The 401 Foundation supports small, grass root projects who build confidence and self esteem, tackle mental health and self development in communities. I thought it was a great fit,” Tyburski said.

In order to create a communal atmosphere, Tyburski knew the course needed to be accessible. As such, he will do loops to cover the distance of each discipline.

While each leg will present its own challenges, the Bathurst native has prepared well.

“There is an element of the unknown for the swim. Since I swam 24 kilometres between Spain and Morocco, I’ve had two shoulder surgeries, and with that, over two years off swimming. [So] I have been a little cautious with training,” he said.

“It’s obviously going to be tough cycling, and then running through the night without sleep, so between the hours of 1am-4am when my body will be literally shutting down to rest, I will need to find something mentally to get me through this time.”

He will have a real time tracker to follow.
