Registration is open for 2021!

The Trek 100 is the best charity bicycle ride of the year, and provides crucial support for the MACC Fund’s fight to end childhood cancer and related blood disorders. This year we will be back in Waterloo, Wisconsin hosting the Trek 100. We continue to monitor health and safety guidelines and will make the wellbeing of our participants and volunteers our top priority. If you are unable to join us in Waterloo please participate virtually on your own ride as we continue to support the MACC Fund both in Waterloo and from our favorite rides across the world. Please Join us on August 21st, 2021.
