AMONG the 80,000 people taking part in this year's City2Surf marathon was a group of fit Bossley Park High School runners and walkers.
The group of nine included one student, a handful of teachers from the science faculty and some of their family members.
"I decided to do it because it's a challenge," said science teacher Katherine Birkett. "It was something I wanted to achieve.
"We did it to raise money for the Children's Medical Research Institute because they do a lot of good research into genetics, and the diseases that are caused by genetics, and also have really good education programs."
The team raised $1515 in donations.
"It was a great experience," said school vice captain Andrew Kehris. "It was my first time running the comp, but I'll be going next year."
All members of the Bossley Park team finished the 14km race.
"It's a good long walk so you should probably do some training beforehand," said Ms Birkett. "It had beautiful scenery and there's a great sense of community. I'd encourage it even if you feel you couldn't run it."
