Fernway — a trail-running route planner (web + watch sync).
Who: weekday runners in cities who want to get off the road without planning for an hour.
Core flows:
1. Onboarding: pick home area, typical distance, surfaces you like, connect a watch.
2. Find a route: map + list of quiet trails near you, filter by distance, climb, surface, loop vs out-and-back, and traffic (how busy it is at this hour).
3. Route detail: map, elevation profile, surface breakdown, recent conditions reported by other runners, and Send to watch.
4. Run & log: after the run, the activity syncs back; rate conditions in one tap.
5. Weekly view: mileage, climb, and a suggested quiet route for the weekend.
