Cycled around the world in her 50s but that's just the beginning of this story

"When she resolved to cycle round the world, Mustoe was 54, somewhat overweight and unfit, and without any idea of how to mend a puncture. She had not ridden a bike for 30 years, wobbled when she tried again, and she hated camping, picnics and discomfort."

H/T to Jack Mulligan!
