GPNEMBA is the non-profit, all-volunteer advocacy & trail development organization for Greater Portland mountain biking. We are on a mission to develop Greater Portland into a world-class mountain biking community by 2030, and are pursuing that mission by:
-Collaborating with land managers to increase & improve mountain bike access & development of world-class trails. Find our more about our current trail projects here.
-Organizing and leading 4,000 hours of volunteer trail work annually (most for multi-user trails) and working with professional trail builders on new projects every year
-Fundraising to bring world-class trail builders & trails to Greater Portland
-Organizing & leading weekly group rides to connect local riders and build a radical mountain bike community. Find out more about our group rides here.
