The 'Answer for Cancer Tour 2011' motorcycle tour will be rolling through Toronto on July 31 to promote awareness of cancer prevention.
The 65-day ride has already raised over $400,000.
The four bikers -- three of which are Canadian -- have travelled over 20,000 kilometres across North America, and will take a break in Toronto to talk to the media about their cause.
The tour has included several stops throughout the U.S. and Canada for the bikers to meet with survivors and those affected by cancer.
All bikers are encouraged to join at any point of the tour.
