Several years ago, Mina Guli set out to run 100 marathons in 100 days, seeking to draw attention to the water crisis.

62 runs in, she was dealing with a labral tear and a 15cm fracture in her femur.

Most people would probably give up at that point, but Mina paused, recovered, and is now setting off on 200 marathons over the next year.

In the Drawing Room, Mina describes what keeps her going and why she sees this as the central crisis of our time.
