When you register for the Tri-State Trek, you commit to fundraising for our mission AND riding your bike. There are many flexible participations options for beginner cyclists, experienced athletes, and incredible volunteers.
The Tri-State Trek unites participants in the fight to end ALS, also known as Lou Gehrig's disease. Through the Trek we fundraise, connect with our Trek Family, celebrate life, remember those we've lost, and advance research to find treatments and cures for ALS.
