Over the weekend 128 crossfit competitors went head to head in an ultimate challenge raising money for the Lake Cathie RFS.
Hosted by North Brother Crossfit, organiser Steve McCarthy said it was a great chance for the community to support the ongoing fire effort and have a good time.
"The competition was a lot of fun and together we raised $6000 for the Rural Fire Service at Lake Cathie," Mr McCarthy said.
"We are really proud of how much money we were able to raise and it is thanks to our generous community."
The competition pitted athletes against each other completing a range of different activities and exercises including burpees and working out on the rowing machine.
"In the end I think we had just as many spectators as we did competitors which meant there was lots of cheering going on," he said.
