Unofficial Trail Authority — Notices Nonbinding directives and notices. Not a government publication. 2026-11-07T00:00:00Z https://trailauthority.org/notices/ Office of the Commissioner EC-14: Non-Revision of Built Features https://trailauthority.org/notices/ec-14/ 2026-11-07T00:00:00Z A feature under the care of its builders is left as they made it. Riders do not soften, enlarge, or tidy it. QD-08: Undesignated Corridor Non-Publication https://trailauthority.org/notices/qd-08/ 2026-11-06T00:00:00Z An undesignated trail is not posted, pinned, or captioned with a way to find it. A picture may remain. The place may not. FN-3: Minimum Viable Gnarliness https://trailauthority.org/notices/fn-3/ 2026-11-05T00:00:00Z A trail should remain interesting to a person who came to ride. Sanding it down for a hypothetical stranger is below the minimum. SV-11: Speed, Practice, and Getting Faster https://trailauthority.org/notices/sv-11/ 2026-11-04T00:00:00Z Going fast is a legitimate purpose. Training is the attempt to improve one's own interval. A trail speed assessment may be treated as an important day. PS-2: The Unmissed Afternoon https://trailauthority.org/notices/ps-2/ 2026-11-03T00:00:00Z A bicycle, an available trail, and a friend who would say yes are a complete set of conditions. The office recommends that the set be used.
