The Team In Training (TNT) program has set the standard for charity endurance sports training. Whether you choose a full or half marathon, triathlon, cycling or hiking event, TNT coaches will prepare you to cross the finish line with workouts, nutrition, hydration and injury prevention clinics. Fundraising will be made easy with staff support.

Since 1988, more than 600,000 Team In Training (TNT) participants have helped The Leukemia & Lymphoma Society (LLS) raise more than $1.4 billion to find cures and ensure access to treatments for blood cancer patients. Join TNT today to make memories that last a lifetime and save lives!

Team In Training is now accepting applications for the 2015 Boston Marathon. If you want to complete this historic marathon while raising as many funds as possible for blood cancer research and patient programs, please click HERE.

"Team In Training guided me every step of the way. When I explained that I could not run ONE mile when I signed up, they reassured me I would cross the finish line... If you think you can't do this, I am LIVING proof that you can. That you NEED to. Listen, I am not joking when I say I couldn't run 1 mile. But I trained. I trained hard. And I crossed that finish line never once questioning if I would make it to the end. I KNEW I would." Read More.
