At 788 feet of vertical elevation, the Columbia Center in downtown Seattle is one of the tallest buildings west of the Mississippi. It takes 69 floors, or 1,311 steps, to reach the highly acclaimed Sky View Observatory with breathtaking views of the entire Puget Sound region. The Leukemia & Lymphoma Society’s Big Climb event raises money through individual and team fundraising, sponsorship and entry fees which is then invested in its mission to fund blood cancer research and support services for patients and their families. In 2018, the Big Climb raised a record-breaking $3,007,080. Big Climb Seattle will be taking place on Sunday, March 23, 2025.
Registration is FREE for all participants up to 30 days before your event. After the 30-day mark, registrants pay $50 to make the Big Climb experience special in every city – separate from your fundraising.
