My longest was a month-long tour from Moncton to Prince-Edward Island, then Newfoundland and back all the way through Nova Scotia, the East and North side of New Brunswick, and in Québec the Charlevoix area... til home in Trois-Rivières.
Apart from that I have done lots of 1-2 week tours.
Lately, I have done two 4-day tours and one 11-day tour with my eldest daughter and one 4-day tour with both of them. I'm planning another one this summer which might be a mixed formula : 2 weeks with both of them and 1-2 weeks riding all by myself, who knows.
