Walnut Grove Secondary students conquered the wall to raise money for the Terry Fox Foundation on April 8.
The second annual Tuff Wally event coincides with an annual school-wide walk that has been held since 2005.
The idea for the more competitive event began with two Walnut Grove teachers, Jeff Keen and Logan Kitteringham, along with students Cyrena Timmins and Emma Smithson.
Students compete in teams of five to get through an obstacle course.
The course began with a short run, which ends with a steep hill up 88th Avenue. Then the obstacles start with a set of machine tires that have to be flipped, a slip and slide, a knees-high tire run, a rope crawl and balance beam.
All the while other students get to bombard them with water guns and water balloons, said Keen.
The last obstacle is the 10-foot high wall which has to be tackled as a team.
An after party organized this year by the student council included a DJ, inflatable games, food trucks, and a dunk tank.
Principal George Kozlovic was one of the first into the tank, and was dunked by a student with an accurate throwing arm.
Several local sponsors offset the cost of the event and got their names on the giant will in return.
The Tuff Wally, along with an annual Bus Pull event and classroom donations raised $6,000 for the Terry Fox Foundation.
Keen said the school hopes to raise even more next year.
