Diefenbaker's Bike-A-Thon is Coming!


What is the "Ride of the Chiefs" Bike-A-thon?

A 24 hour stationary bike relay event to support the Alberta Children's Hospital program, "Kids Helping Kids". This event will take place in the Diefenbaker Main Gym from Friday April 13 to Saturday April 14th, from 8am to 8am. We hope to pack the gym with spin bikes and 25+ teams of 6-10 riders who will unite for this amazing cause!
