The annual Leukemia & Lymphoma Society (LLS) Big Climb will take place at 7 a.m., January 25, at the Bank of America Plaza in Dallas. Participants will be challenged to ascend 70 flights (more than 1,500 steps) of stairs to the top of the building and raise critical funds in support of cancer research and patient support.

Teams of coworkers, families and friends will compete in a friendly competition to raise the most money for blood cancer research and patient access. In addition to the registration fee, participation in Big Climb requires a minimum fundraising commitment of $100.

LLS is the largest funder of cutting-edge work to advance cures, investing $1.3 billion in research. They are leaders in breakthroughs in immunotherapy, genomics and personalized medicine. These revolutionary new treatments originally discovered through blood cancer research are now being tested in clinical trials for other cancers.

Location: 901 Main St., Dallas. Registration is $50 until event day at lls.org/events/big-d-climb-0.
