Know exactly
what to run today

RunCraft connects your plan, completed runs and recovery — so today’s session reflects the runner you are now, not a template you downloaded weeks ago.

The problem was never effort

Runners who stall aren't lazy. They're guessing — and this is where it shows.

Every run comes out the same medium-hard

Easy days too hard to recover from, hard days too tired to be fast. You train constantly and plateau anyway.

The plan you found online wasn't written for you

A PDF off the internet assumes someone else's fitness. Its paces are either a jog or a race, and you can't tell which.

You're adding distance and hoping nothing breaks

The ramp feels fine right up until it doesn't. By the time it hurts, the mistake is three weeks old.

You finish a run with no idea if it was any good

The watch says 8 km in 44 minutes. It doesn't say whether that was the session you meant to run.

How RunCraft answers

Every situation, handled

“How fast is my easy pace, really?”

Your paces, from a result you actually ran

Enter one race or time trial. RunCraft turns it into your VDOT score — and your VDOT score into every pace you train at. “Easy” finally has a number.

  • Easy, Marathon, Threshold, Interval and Repetition paces
  • Honest race predictions from 5K to marathon
  • Paces move as your fitness does — no manual resetting

“It's 6am and I don't want to make a decision.”

Today's session is already waiting

A periodized schedule, built backwards from your race date. No morning starts with a blank page — glance at the Lock Screen and today is already decided.

  • Widgets put today's session one glance away
  • Recovery days adjust when your readiness dips
  • No race on the calendar? Run a simple weekly routine instead

“The plan says intervals, but recovery says otherwise.”

Your coach notices before you have to ask

When sleep, HRV, resting heart rate or recent load points to recovery, RunCraft shows one clear recommendation inside your plan. You decide whether to apply it.

  • Explains the signals behind the recommendation
  • Adjusts today — not your entire plan
  • Never interrupts with a forced pop-up

“The data looks normal, but I don’t.”

Tell the coach what the sensors missed

If you feel unusually tired, sore or unwell, report it when it matters. This is an escape hatch, not a daily wellness questionnaire.

  • Three focused states instead of a medical questionnaire
  • A bounded adjustment to today’s coaching
  • One report never rewrites the whole plan

“I can't run 30 minutes without stopping yet.”

Start from walking, not from shame

Not every plan should start at 5K. The walk-run progression begins where you actually are and builds to 30 minutes non-stop.

  • Alternating walk and run intervals, timed for you
  • Progression paced to weeks, not willpower
  • No Apple Watch needed — the iPhone can guide the whole run
“I’m not training for a race.”

Build consistency without inventing a finish line

Choose a simple weekly routine or just track your runs. Change direction whenever you want.

  • Repeat on the days that fit your week
  • No race date or VDOT required
  • Switch to race training when you are ready
“I finished. Was that good?”

See what happened — and what it means

RunCraft connects the session you meant to run with the run you completed, instead of leaving you with an isolated finish time.

  • GPS route, splits, pace and heart rate in one review
  • Effort and weather add the context sensors cannot explain alone
  • Readiness, training balance and VDOT trends show what comes next

“Am I ramping up too fast?”

Something is watching the ramp for you

RunCraft watches your acute-to-chronic load — this week against the base you've built — and speaks up before the jump becomes an injury.

  • Weekly load trend shown as a plain-language banner
  • A warning when the ramp crosses into risk
  • An 80/20 check that keeps easy days honestly easy

“My coach gave me a session no app understands.”

“That one was worth remembering.”

A card worth posting

Some runs earn a photo. Drop in your own shot and RunCraft lays the stats over it — no cluttered dashboard screenshot required.

  • Your photo, your run, clean stats on top
  • Sized for Instagram stories

Mid-interval is the worst time to do math

“Am I on pace right now?”

Run the session, not the arithmetic

Start today's workout from your wrist and RunCraft carries it: a target, a tap when you drift, a count of what's left. Your attention stays on running.

  • Live pace target with on-target feedback
  • Heart-rate zone display with haptic alerts when you drift
  • Interval progress — rep count, distance remaining
  • A complication that puts today's session on your watch face

The iPhone mirrors the session live

Pull out your phone mid-run and the same workout is there — rep counter, live pace, heart-rate zone — in sync with your wrist.

  • Live rep progress mirrored from the watch
  • Pace, heart-rate zone and cadence at a glance
  • Pause or end the workout from either device

Why it works

Built on VDOT, not guesswork

Training paces start with Jack Daniels’ VDOT, then recent volume, completed sessions and recovery keep the plan grounded in what you can do now. Your own report fills the gap only when the sensors miss something.
