Two flats within 2 kilometres today. Both front, tiny silvers of glass. Pouring rain. While fixing the second flat I noticed that a cut in the sidewall of my rear tire, which I had previously booted, was bulging dangerously. I took out the sewing kit and sewed the cut shut. It now bulges only slightly. While sewing my rear tire, a front spoke nipple failed (spontaneously). I took a nipple from one of my spare spokes and replaced the failed one. Total time spent on the side of the road: two hours.
