Trans Adirondack Route thru-hikers like to get away from it all, and they may possess a friendly competitive spirit. In adventure sports parlance, a fastest known time, often shortened to "FKT," is a record of who traversed what the fastest. We recognize two styles of fastest known times – supported and unsupported.

During supported attempts, almost anything goes. Runners are usually fully supported by a crew that cooks their food, resupplies them at road crossings, shuttles their gear, etc. During a supported attempt, two rules apply. 1) Cover the entire route. 2) Navigate by map and compass only (no use of GPS, phone, satellite devices, etc.).

During unsupported attempts, anything doesn't go. Friends of the Trans Adirondack Route demands unsupported thru-hikers follow five rules. 1) Cover the entire route. 2) Navigate by map and compass only (no use of GPS, phone, satellite devices, etc.) 3) Carry all your own gear. 4) Resupply no more than three times. 5) Stay in accommodations (motels, hostels, friends' houses, etc.) no more than three nights.
