TrailForge: Trail Run Training

TrailForge is the planning app for trail and ultra runners who coach themselves. Plan your training in the units the sport actually uses — vertical gain and time on feet — then turn the same preparation into a race-day plan with pacing, weather and fuelling for your course.

Most running platforms were built for the road: they measure your week in flat kilometres and treat elevation as an afterthought. TrailForge plans in vert and hours from the start.

PLAN YOUR SEASON
• Build multi-week training plans on your phone — no desktop required
• Set weekly targets in vertical gain and time on feet, not just distance
• A full structured-workout editor: intervals, repeats, ramps, hill blocks
• Plan a backyard ultra with lap-based projections

SEE PLANNED VS ACTUAL
• Completed runs sync back and match themselves to the planned session — scored on date, distance and route, always yours to override
• Watch each week fill in: planned vert against climbed vert, planned hours against hours on feet

PLAN RACE DAY
• Import the course (GPX) and get terrain-aware splits that respect the climbing
• Weather projected along the course — the forecast for where you'll be when you get there, not for the start line
• A fuelling plan with carbs, fluids and sodium spaced across the race, aid station by aid station

FUEL THAT LEARNS
• After long efforts, a three-tap check-in: did you follow the plan, how was your gut, how was your energy
• Your targets adjust from what actually worked for you — not a generic formula

ROUTES
• Draw routes that snap to trails, or import GPX
• Elevation profile, distance and climbing for every route
• Follow your route in the field

WORKS WITH YOUR WATCH
• Push planned workouts and routes to Garmin
• Import completed activities from Garmin or Strava
• Splits, grade-adjusted pace, heart-rate zones and elevation for every run
• Home Screen and Lock Screen widgets
