AI Running Coach
That Adapts to You.
PacecraftAI is the AI running coach that turns your data into a personalised training plan, adapts it every week to your fitness and recovery, analyses every run you log, monitors injury risk, and prepares you for race day — from first 5K to full marathon. Pro free for 2 months during launch — no credit card needed.
More than a training app —
a coach that actually knows you
From first 5K to competitive marathon — PacecraftAI uses your real biometric data, GPS runs, and history to coach you like a pro.
Built-in GPS Run Tracking
Track runs and walks directly in the app — no Strava, no Garmin needed. Live map, auto-pause at traffic lights, per-second pace, and GPX export. Your coach gets your run data the moment you finish.
Health Connect Integration ANDROID
Syncs 13 health data types from your wearable — sleep stages, HRV, resting heart rate, VO₂max, SpO₂, steps, and more. When you ask "Am I ready for a hard session?", your coach checks your actual sleep and HRV first.
Training Load Dashboard
A full fitness dashboard on every login — radar chart across 6 dimensions, ATL/CTL training load, weekly mileage, streak, pace zones, and an AI-generated coaching summary card. Data served from cache — loads instantly.
Adaptive Training Plans
12–20 week plans that evolve weekly based on your performance, fatigue, and goals. PacecraftAI adjusts mileage, intensity, and recovery — and builds the plan from your benchmark run on day one, so there's no empty state.
Proactive Daily Coaching
Good Morning briefing at your chosen time — today's workout, training load, weather-adjusted paces. Evening recap — what you did, what tomorrow looks like. Race countdown messages at D-7, D-3, and D-1. All written fresh by AI, not templates.
Real-Time AI Chat
Messages arrive instantly via Server-Sent Events — no polling, no refresh. Ask about pacing, injury, nutrition, race strategy. Your coach remembers your training history, goals, and coaching notes across every session.
Injury Risk Monitoring
ACWR (acute/chronic workload ratio) tracked automatically. If your training load spikes into the danger zone, your coach flags it and adjusts your week before you get hurt. Unresolved concerns get a follow-up the next day.
Race Day Countdown
Personalised D-7 taper guidance, D-3 carb-loading and mental prep, D-1 final checklist and race-morning pacing strategy. Each message written by the AI based on your specific race, fitness, and goal time.
Built for every runner,
from first 5K to Boston Qualifier.
Wherever you are in your running journey, PacecraftAI builds a plan for exactly that stage — and adapts it as you grow.

Coaching that actually talks back
Ask anything — pacing, injury, race strategy, nutrition. Your coach responds in seconds.
Real coaches don't take weekends off.
Neither does PacecraftAI.
"I'd tried three different training apps before PacecraftAI. None of them adjusted when I got sick in week 8. PacecraftAI noticed my HRV had tanked, flagged it, and shifted my long run back automatically. Finished my first marathon in 4:31."
"The D-7, D-3, D-1 race countdown messages were incredible. My coach knew my exact training history and goal time — the D-1 pacing strategy was better than anything a human coach would write. Sub-4 for the first time."
"I asked 'should I run today, my knee feels off?' at 11 PM. It told me to rest, explained what my ACWR ratio meant, and suggested a swim instead. That kind of 24/7 access to a knowledgeable coach is just not possible with a human at this price."
"I came in with zero running experience and was honestly scared. The beginner plan felt totally manageable, and whenever I had a bad week the coach adjusted without making me feel guilty. Ran my first 10K in under 58 minutes three months later."
