Base 2 Space

Seattle’s Most Iconic Climb

We are unable to host Base 2 Space in person this year due to the ongoing global pandemic. We will host the traditional climb in the future.

Thank you for your support in making Base 2 Space Seattle’s most iconic climb! Over the last five years, we’ve loved climbing with you, celebrating with you, and most importantly, raising money with you in support of cancer research.


With no in person climb this year, we're excited to host the Base 2 Space Challenge in 2020! Lace up your shoes, climb 832 steps, and connect with other climbers — no registration required. Here's how to join in:

  • Mark Your Calendar: The challenge will take place Friday, September 25 through Sunday, September 27, 2020. You can complete the challenge all at once, or over the course of the weekend.
  • Make A Plan: Find stairs close to home — inside your house, at a city park, or using public stairways in your neighborhood. Be sure that the stairs aren't crowded, wear a mask, and maintain a safe physical distance.
  • Share Your Climb: Show the world how you're climbing in 2020 by using #Base2Space2020 on social media.
  • Donate: No registration or donations are required to participate; we're hosting this challenge to connect our climbing community. If you're able, make a donation and continue to support groundbreaking cancer research at Fred Hutch.


Scale the tower’s 832 open-air stairs and take in incredible views of downtown Seattle, Mt. Rainier, and the Puget Sound region’s surrounding beauty as you ascend to the top of Seattle’s most iconic landmark. The fifth annual Base 2 Space was held in 2019; over the five years of the event, it has raised over $3 million. All donations raised benefit Fred Hutchinson Cancer Research Center and the Space Needle Foundation.


Fred Hutch researchers are continuing groundbreaking cancer research, including new findings on breast, lung, and blood cancers, tumor growth, and targeted treatments. Our experts are also at the global frontlines of the coronavirus pandemic: tracking infection, guiding the public health response, and overseeing large-scale trials of new vaccines and treatments.
