Tough ride this morning. I flatted right outside a local highschool. I felt a bit rushed to get the new tube in, and neglected to check the inside of the tire for sharp bits. Sure enough, 5km later I was flat again. I only carry one spare tube, so I had to walk the last stint to the office.

I also learned that my mini-pump (Planet Bike micro-mite) doesn't really put out much air. Sure, it's better than nothing but now my arms are very tired!

Looks like I'll have to break out the patch kit at lunch.
