Sliderider

Hurtling down a 150m water slide doesn't sound too much of a hardship, so the fact that the Sliderider is being set up at Ally Pally to raise funds for Cancer Research UK's Kids and Teens campaign means that you'd be a true spoilsport to give it a miss. Each ticket allows two slides and can be booked in advance on the Cancer Research UK website. Open to ages 12 and over.
