My bike does have a rack so I was thinking of using one or two panniers. Also I like how the weight is low when you use panniers. I plan on having fresh fruit and maybe an energy bar for a snack, otherwise eat at restaurants. I will be along the lake Ontario bike path so food should be very easy to get. I plan on having a few off bike clothes and two pairs of shoes (should one get wet).

I have a small air pump, what other tools should I bring? On my past bike tours I took way too much stuff.
