The Event

How it Works

The STIHL Tour des Trees is a weeklong, 500-mile cycling tour with an ambitious agenda:

  • To fund important research focused on improving the health of urban trees
  • To fund education programs aimed at connecting young people with the environment and with opportunities in the green industry
  • To raise awareness in the communities we visit of the importance of trees to the quality of urban life and the value of science-based professional tree care.
  • To engage and educate young people about how trees grow, why people need trees and how they can help care for the trees in their lives.

Every full-Tour participant  commits to raising a minimum of $3,500 for the TREE Fund in addition to pedaling 500+ miles in a week, rain or shine. They do it for the challenge, the mission and the camaraderie. Their legacy is a promise of strong, healthy urban trees for generations to come.

STIHL Tour des Trees cyclists experienced some of the best cycling in the US when the Tour journeyed to Wisconsin July 27-August 2, 2014. 

Tree plantings and community engagement are hallmarks of every Tour, and Professor Elwood Pricklethorn (aka Toronto arborist and veteran Tour cyclist Warren Hoselton) provided educational programs for young audiences along the way. The Tour also added about 20 new trees to the growing urban forest planted by its cyclists.

The 2014 Tour concluded August 2 at Mount Mary College, site of ISA’s  International Tree Climbing Competition and Arbor Fair.

Since 1992, the Tour des Trees has generated more than $6.6 million and has funded a variety of research projects and educational programs for budding tree care professionals. To learn more, visit the grant and scholarship archive pages at

The continued success of the Tour des Trees is directly attributable to the support of its Sponsors. Corporate sponsorships ensure that the money raised by Tour riders is applied to research and education programs, not event costs. The TREE Fund gratefully acknowledges the support of our Partners and Sponsors, without whom this event would not be possible.

Rider registration for the 2015 in Florida will open January 12, 2015, and is limited to 100 full-Tour riders.
