Save the date: Saturday, June 8, 2024

The Trek 100 began as a humble charity 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 10, 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!

An entirely revitalized ride

Think you know the Trek 100? Think again. Riders who’ve joined us for the past 30 years will be delighted to experience an entirely new Trek 100 in support of the same awesome cause.

New routes and rest stops

You’ll enjoy four totally new route options on beautiful Wisconsin backroads, entirely revamped rest stops stocked with incredible snacks, and a non-stop party with plenty of family-friendly fun.

Same great 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 $82 million to this important case.

Pedal. Party. Repeat.

There's nothing better than a tasty treat during a looooong ride. At the Trek 100, you'll enjoy rest stops stocked with snacks like banana split sundaes, hamburger sliders, and s'mores — complete with live music, free gear, and a few surprises along the way.
