The world's fastest longboarders took to the streets of Calgary this weekend, slowing down long enough to pay tribute to Duncan McRae, a 13-year-old who was killed in a longboarding accident last week.

The IGSA World of Downhill Skateboarding championships wrapped up at Canada Olympic Park on Sunday.

The competitors and spectators had a moment of silence for McRae, and dedicated all of the competition's final races to him.

Duncan's father Sandy McRae says longboarding is a safe sport, with athletes that have been very supportive.

“It's overwhelming that they would think of doing this for Duncan, but it's not surprising now that I'm here,” said McRae.

“Duncan would have wanted to do this today. He would have been on me to see who I could talk to to get a helmet and at least go halfway up to give this a go.”

The McRae family was given two memorial longboards inscribed in Duncan's honour.

The flags at COP were flown at half-mast.

A memorial for McRae will be held at 3 p.m. MT Monday at the First Alliance Church.

In lieu of flowers, donations can be made at memorial funds at Scotiabank or the Alberta Treasury Branch.
