About this event

Part of the Rat Race Bucket List Series

Are you ready to take on the challenge of a lifetime to fight the injustice of cancer in children?

In a remote corner of North-Western Mongolia lies Lake Khövsgöl: one of 17 ancient lakes in the world, over two million years old. In winter, the ice freezes across its near 100-mile length to a depth of over a metre thick becoming the ultimate adventure course for those brave enough.

The Mongol 100 objective is to travel across the frozen lake from north to south, by any means necessary. You can complete it on foot, using skis or even on a bicycle!

Children with Cancer UK is the official charity partner of the Rat Race Bucket List Series. By joining our team you will be helping to fund life-saving research that will save the lives of children and help keep their families together for longer.

What to expect from Children with Cancer UK

The Children with Cancer UK Team will receive the following:

  • A dedicated point of contact at the charity
  • A Children with Cancer UK fundraising and training pack
  • Regular Children with Cancer UK updates
  • A technical Children with Cancer UK T-shirt to wear with pride
  • Free Rat Race backpack (ideal for use on Bucket List events!)
