Team-in-Training is one of the oldest endurance training programs in the world. Since 1988, over 220,000 people have run, walked, biked, cycled or skated as a way to raise money for the Leukemia & Lymphoma Society (LSS). Participants train for a chosen event with the help of experienced coaches and enthusiastic fellow teammates. In return, they pledge to raise a certain amount of money for LSS. The amount of each pledge is set at 25% to cover a participant's expenses and 75% to LSS for their research, patient aid and outreach programs.
