Trail running starting points
Unpaved trails of a mile or more: a computed place to start, not an endorsement.
We mark a trail as a running starting point when it is mapped as unpaved and is at least a mile long. That is all the data can tell us.
Footing, steepness and traffic matter more than the label. The route builder can give you a flat-ground time at your own pace.
By the numbers
Numbers describe the 20 longest trails listed below, not every trail with the feature. Climb is known for 20 of them.

Good to know
- Climb is shown where we have it: steep trails are slower than the flat-ground time.
- Bikes and horses may share the trail: check the access tags on the trail page.
How this list is made
Unpaved trails of a mile or more: a computed starting point for runners, not an endorsement of any route. The list is ordered by length (longest first), not by quality: we don't rank trails by opinion. Trails under a quarter mile are hidden.
