STIHL® Tour des Trees

This weeklong, 500-mile cycling event is held annually to benefit the TREE Fund. Since 1992, the Tour des Trees has raised over $7.2 million for scientific research and educational programs related to arboriculture and urban forestry. All full-tour cyclists commit to raising at least $3,500 for the TREE Fund to support the discovery of better methods of propagation, planting, and care of urban trees. This event also:

Funds educational programs to connect young people with the environment and career opportunities in the green industries.
Leaves a legacy of an ever-expanding urban forest planted by its cyclists as well as a better understanding for residents in its destination communities for the trees that shade their lives.
