Register for the Local Challenge and join us at the start line as we come together in Lewiston/Auburn Maine

To ensure proper planning for the number of people registered for our in-person event, participants who register for the Local Challenge (taking place in Lewiston/Auburn, Maine) will need to reserve your spot by meeting the fundraising minimum by September 23. If the minimum fundraising has not been met by the deadline, you forfeit your spot for the in-person Local Challenge.  We will automatically change your participation to the Global Challenge where you will be able to participate virtually.

Local Challenge participants will have the option to switch to the Global Challenge at any time, however if you wish to change from the Global Challenge to the Local Challenge, you will need to do so by September 23. At this time, we will not be able to accept any walk-up registrations for the in-person Local Dempsey Challenge. Please be sure to register and hit your fundraising by September 23 if you want to participate in person.

There is no penalty if you do not hit your fundraising minimum as a Global Challenger. Questions? Contact us at [email protected]
