Big Climb brings you inside Citi Field, home of the New York Mets, where we turn the stands into a powerful path forward for blood cancer patients and survivors.
Whether you're climbing stairs, navigating ramps, or feeling the energy of a city that never backs down, every step supports the mission of Blood Cancer United, formerly LLS.
This is more than a fitness challenge. It's a bold stand for progress, community, and cures.
Sign up and rally your coworkers or lead a team of friends or family. Registration is free until 30 days before your event-after that, a $50 contribution applies and goes toward your $150 fundraising minimum. Start your climb strong and invite your community to join you. Every climber counts.
From the moment you check in, Big Climb is more than an event-it's a powerful, shared experience.
You'll start your day at Base Camp, a gathering space filled with energy, connection, and activities for climbers of all ages. When it's time for your assigned Climb Time wave, your team will be led to the starting area, where we'll come together for a brief but moving Opening Ceremony-honoring the stories, people, and purpose behind every step.
Then, the climb begins.
Whether you're navigating stadium stairs, ramps, or concourses, you'll be guided by route arrows, high-energy music, and the cheers of volunteers there to lift you up. Along the way, you'll see the names and faces of those we climb for-patients and survivors whose strength inspires every step.
And when you cross the finish line, you'll receive your finisher medal-a symbol of strength, solidarity, and your role in moving us closer to a world without blood cancer.
As a climber, you're taking on more than stairs-you're helping change lives. Each climber commits to raising at least $150 (or $50 for youth ages 8-17) to support the mission of Blood Cancer United. We'll provide the tools, support, and incentives to keep you motivated. Check out the tips and tools page for fundraising support.
Every dollar you raise takes us closer to a world without blood cancer-and we celebrate your impact along the way. At $150, you'll earn your official 2026 Big Climb medal. Raise $250 to help fund patient and caregiver support groups and unlock the Big Climb T-shirt. Push past $1,000 to fuel research breakthroughs and claim your Climb Master cap.
