The Ride to End ALS

Since 2003, people have been riding hundreds miles every summer to support ALS research at ALS TDI.

Register for the 2021 Tri-State Trek!

The 2021 Tri-State Trek is happening this summer and we want you to join us! This annual event aims to bring the ALS community together to raise awareness and funds for ALS research at the ALS Therapy Development Institute (ALS TDI).

This year, we will be hosting the 2021 Tri-State Trek with three options to participate! Whichever option you choose, you are part of our #TrekFamily and are contributing to our larger mission to end ALS.

Important notes about the in-person Tri-State Trek:

Due to COVID-19 restrictions, we will not be able to allow spectators or guests of any kind at this year's in-person event. All participants, cyclists and crew members are required to follow our strict requirements including daily temperature checks, standing 6 feet apart and our “Feet on the Ground” protocol: When not actively cycling or eating, all must wear protective face masks covering nose and mouth. To maximize appropriate social distancing, this event will be held entirely outdoors and all meals will be catered as “grab and go”. Sanitation stations and resources will be on-site to ensure a clean and sanitized gathering. Additional guidelines may be added and mandated by ALS TDI based on recommendations by the CDC.
