The Trek 100 provides crucial support for the MACC Fund’s fight to end childhood cancer and related blood disorders. This year, the risks associated with COVID-19 have made it impossible to host a group ride from Waterloo—but you can still make a difference, and your participation matters now more than ever.Collect pledges in support of the MACC Fund and ride the route of your choosing on August 22nd.

“The Trek 100 is always the MACC Fund’s biggest fundraiser—but this year, because we’ve had to cancel our other events, it will also be our only fundraiser. We’re relying on the generosity and commitment from you and other riders in the cycling community. Your support in helping end childhood cancer matters more this year than ever!”

-Jon McGlocklin MACC Fund President
