Plan the route. Plan the fuel. Let the run log itself.

Fuelling

Nobody bonks on purpose.

Attach a fuel plan to any session and TrailForge reads the whole picture — how long you'll be out, how hard you're going, how warm it'll be at the start line, how much you weigh — then hands you carbs, fluid and salt per hour, with the reasoning in one plain sentence. Conservative, Balanced or Aggressive to start; change anything you like.

• It pushes back when it matters. Past 60 g an hour your gut can only take so much of one sugar — TrailForge says so, and tells you to add a second. It catches salt that's too thin for the fluid you're carrying, and caffeine that'll still be with you at bedtime.
• Plan the vest, not a spreadsheet. Pick the gels, mixes and chews you're actually carrying — from the catalogue or your own — and TrailForge spaces them into a schedule you can follow on the move.
• Then it learns your gut. Log what you actually took and how you actually felt. Two good runs in, it stops quoting the textbook and starts quoting you — held below the intake that's caused you trouble before.

Routes & weather

Draw the line, then see the day it's going to be.

Tap out a route and it snaps to real trails and paths. The climbing you see is the climbing you'll do — read straight off the terrain, with no phantom vert padding the number. Drag a finger along the profile and watch the hill move under it.

• The best hour to leave. Tell it the temperature and sky you like running in and how far you're willing to shift, and it reads the whole day to find your window.
• Weather where you'll actually be. Temperature, rain, wind and gusts projected along the route at your pace — not just what it's doing at the trailhead.
• It knows when the light goes. The dark stretch is shaded straight onto your elevation profile, so you pack the headlamp before you need it, not after.

Worth knowing: routes are drawn here, imported from a GPX file, or arrive from Strava — and they push back out to Garmin as courses.

Analysis

Pace lies on a mountain.

A brutal climb and a bad day look identical in raw minutes per kilometre. TrailForge puts grade-adjusted pace next to the real number, so the effort you actually put in is the one you get credit for.

• Splits that account for the hill. Every kilometre with its climb, its descent, its heart rate — and what your pace would have been on the flat.
• Zones with names, not numbers. Tap through Recovery, Endurance, Tempo, Threshold and Max and see where the session really sat — then break it down lap by lap.
• Read a whole week at a glance. Every run in the list carries its map and a colour bar of the effort, so a block of training tells its story before you open anything.
