Tackle Cancer Challenge turns everyday movement into cancer treatment donations. For the time of a challenge, people all over the world walk, run and ride together toward one collective distance goal. Thanks to the generosity of our partners, each milestone the community reaches adds a treatment donation to RLT-Connect, the Oncidium Foundation's treatment donation program for targeted radionuclide therapy. HOW IT WORKS • Log any activity — walking, running, cycling and more. • Import automatically from Apple Health, or enter your activities by hand. • Steps, minutes, kilometres and miles are all converted into distance toward the goal. YOUR TEAM Create a team or join an existing one, follow its contribution to the challenge, and see how it stands against the others. You can also take part on your own. THE COLLECTIVE JOURNEY The global goal is split into sectors. Watch them light up one after another, see which participant crossed each milestone, and follow the challenge live. FRIENDLY COMPETITION Track your position among all participants, within your team, and your team's rank in the overall standings. SHARE THE MOMENT Add a photo to an activity and post it to the community feed. Follow and like what other participants are doing around the world. ## Is Tackle Cancer Challenge safe?
