Trek 100 - a life-changing bike ride supporting MACC fund

Join us in Waterloo, WI for the Trek 100

Saturday, June 7, 2025

The Trek 100 began as a humble charity bike ride to raise funds for childhood cancer and related blood disorder research. But over the last three decades, it's grown into something so much bigger. Since 1990, we've raised over $22 million for the MACC Fund — and on June 7, 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!

Incredible routes

Ready to ride? Four incredible routes take you through the heart of America’s Dairy Land and roll right back to Trek Headquarters for a party at the end. Explore the rides and join us for a delightful adventure that supports an amazing cause.

Mind-blowing stops

Bet you can’t guess what we’ll surprise you with this year! Our world-famous rest stops are revamped, stocked, and ready with incredible snacks and a non-stop party with plenty of family-friendly fun.

Life changing cause

Every dollar of your registration and pledges benefits the MACC Fund's efforts to end childhood cancer and related blood disorders. Over the past 45 years, the MACC Fund has contributed more than $87 million to this important cause, fighting for children and their families.

Take Trek 100 to the trail

Prefer the trails over the open road? The Trek 100 MTB ride takes the party to Trek Trails 50 miles (or as many 10-mile laps as your quads can muster). Hammer out miles of singletrack and stop for a party every lap at the trailside MTB rest stop.

See the trails

You can ride easy knowing technical support is always minutes away during the Trek 100. We’ll have a great crew of Trek Certified Technicians and the amazing team at Wheel and Sprocket on hand to take care of any issues you might encounter along the way.
