15th Annual Tri-State Trek


The ALS TDI Tri-State Trek raises money and brings attention to the work ALS TDI is doing to find an effective treatment for a horrific disease.

The Trek began in 2003, when 16 cyclists pedaled from Boston to New York and raised about $30k for ALS research. The event has since grown to over 400 participants, raising over $7 million. People ride, crew or volunteer to support changes in medical science. Riders gain strength from spectators cheering them on with cowbells, letting them know they are not alone on their bikes.

The 15th annual Tri-State Trek begins at Boston College in Newton, MA, on Friday, June 23rd, 2017, and ends Sunday, June 25th, 2017, in Greenwich, CT. The 270 mile course is completely supported to ensure safety, fun, and a great experience. Many of your questions will be answered below, but please do not hesitate to contact us. We are always happy to talk about riding, training, buying a bike, Tri-State Trek logistics or the research at ALS TDI! Learn more
