Trek 100

The Trek 100 began as a humble charity bike ride to raise funds for childhood cancer and related blood disorders research. But over the last three decades, it’s grown into something so much bigger. Since 1990, we’ve raised over $20 million for the MACC Fund — and on June 8, we’ll gather at Trek’s global headquarters once again to ride, party, and support this crucial cause. This is our open invitation for you to join us for the best group ride ever!
