Sheree Middleton participated in the school's fund-raising event The Stampede at Sydney's Glenworth Valley on Saturday with her 13-year-old son Chase cheering her on from the sidelines.

Ms Middleton, whose son attends Hunter Aspect's satellite school based at Waratah West Public School, participated alongside dozens of other parents and teachers as part of Team Aspect.

The team set a fund-raising goal of $8000 to buy much-needed classroom resources for the school.

Ms Middleton and her teammates endured a challenging course, which featured mud pits, rock climbing and an ice bath followed by a hit of 10,000 volts. Ms Middleton said it was all worth it to support the school that has been invaluable to her son, who has Aspergers Syndrome.

"I personally cannot thank Aspect enough for the wonderful work they have done with my son," she said.

"Chase started a very upset and frustrated child aged 8 and will be leaving a confident, well-spoken young man."

Team Aspect raised more than $3000 for the school but it fell short of the team's goal. It's not too late to donate. Go to thestampede2014-sydney.gofundraise.com.au/page/AspectHunterSchool.
