Maribyrnong Valley Park Backyard Ultra

Fri 3rd - Mon 6th Feb 2023

Every hour, on the hour, 6.7km course

You decide how far



How about this – the only race format where you don’t have to be fast to win.  You just need to complete the 6.7km course within an hour – HOUR AFTER HOUR.

And after every hour, those still participating are all tied for first place.  It’s all about management, not speed.

Are you strong minded, perhaps described as stubborn?  You just might be the Last One Standing, THE WINNER!

There are no second places!!
