On May 15th from coast to coast, we climb as one.

We are excited to welcome you to the 35th annual Big Climb Seattle! No matter where you live, no matter what your connection to cancer may be, now you can step up to take cancer down by being a part of The Leukemia & Lymphoma Society’s Big Climb.

Every step you take will help fuel the research and care that has made The Leukemia & Lymphoma Society the gold standard of cancer non-profits.

In 2020, we climbed as one in the face of a global pandemic. In the face of uncertainty, unprecedented challenges, and change, we are so proud to say that our family of supporters, donors, and climbers raised over $1.5 million to support the mission of LLS! In 2021, we will once again tackle Big Climb as a virtual event, climbing from coast to coast together on May 15th as we step up to take cancer down.
