I can say it no better than what is written on the Terry Fox Foundation website:
Many years later, Canadians adopted Terry’s mission of finding a cure for all cancers with an enthusiasm and passion that has done him proud. In keeping with the approach of its founder, The Terry Fox Run (1981 – ) is an innovative and volunteer-led event, all-inclusive, non-competitive, with no corporate sponsorship, incentives or fundraising minimums.
It has become a fall tradition in Canada to gather your friends and family, lace on your shoes, bring our pledge sheets and attend your favourite Terry Fox Run site, where Organizers have no budget for expenses but have unlimited appreciation for your attendance!
The Annual Run in Canada is usually hosted on the second Sunday after Labour Day, the month chosen by Terry to reflect when he had to stop running and when Canadians had to start.
This Sunday is not about a colour, or a bracelet, or sponsors, or a flashy symbol. Perhaps those things have a time and a place, but I hope Sunday is about family, friends, Canada, and moving beyond something that unfortunately touches all of our lives. Continually, the Terry Fox Foundation is a leader in having 85% of funds raised go directly to cancer research.

I look forward to hearing about your run on Sunday.
