About the Event

Simply raise a minimum of $1000 in pledges and rappel down Denver's McGregor Square!  Whether you are an accomplished climber or a first time rappeller whose only use of a carabiner is as a keychain, this event is a thrill of a lifetime. An exclusive event for Cancer League of Colorado, Over the Edge gives participants a life-changing opportunity to rappel approximately 200 ft. while raising money for Colorado based cancer research.

Unique to non-profits, Cancer League of Colorado has no paid staff and no offices. All operating expenses are covered by membership dues and our volunteer staff. Cancer League of Colorado now has more than 400 volunteer members who share the commitment to fight cancer and support cancer research. 100% of all donations go directly to cancer research and cancer patient services in the state of Colorado.
