Trail Care makes it super easy for Strava users to support the trails they use by enabling fast, easy and fun micro donations.

Each time you upload an activity to Strava we'll process it and check if it matches the jurisdiction of any participating organizations. If it does, we'll send you an email asking if you'd like to complete your donation.
