## What is PaceLab?

PaceLab builds your training plan and recalculates it session after session. Like a coach who actually follows you, not a spreadsheet that ages badly.

YOUR WEEK AT A GLANCE
Open the app and you see today's session and the next one. Slide your finger along the timeline to move between weeks. Press and hold a session to mark it done, move it, send it to your watch or take it out of your week.

A PLAN THAT MOVES WITH YOUR LIFE
Pick your goal — 10K, half, marathon, trail, triathlon, sportive, or simply getting back in shape — and your full plan appears, week by week. Missed a session, brutal week at work, wrecked legs? PaceLab reshuffles what comes next instead of leaving you chasing an outdated schedule.

A COACH YOU ACTUALLY TALK TO
The coach has its own tab, laid out like a conversation. Tell it "I'm wrecked", "I'm away this weekend", "I want more hills". It knows your history, your training load and your recent sessions: it suggests a change, you accept it or not, and it explains its reasoning. In English or French.

EVERY SESSION, STEP BY STEP
Warm-up, blocks, recoveries, cool-down: each step with its duration and target pace or zone. Once the session is done, compare what was planned with what you did.

YOUR SESSIONS, YOUR WAY
Create your own running or trail session and place it in your plan, or adjust a workout template. The coach then reuses your version in the following weeks, rescaled to that week's volume.

ON YOUR WATCH
With an Apple Watch, the next few days of sessions show up in the Workout app on their own. For Garmin, Coros or Suunto, export the session as a .FIT file and import it into Garmin Connect or your watch app.

YOUR ACTIVITIES SHOW UP ON THEIR OWN
Connect Strava to import your workouts automatically. On iPhone, PaceLab reads your workouts, sleep, resting heart rate and heart rate variability from Apple Health to sharpen its recommendations.

LOAD AND RECOVERY, MADE READABLE
Fitness, fatigue and freshness (CTL / ATL / TSB) day by day, plus the acute:chronic workload ratio (ACWR) that warns you when your build-up turns risky.

GENUINELY MULTI-SPORT
Running, trail, cycling, swimming, triathlon, strength, hiking, rowing. Each sport gets its own zones: VO2max and threshold pace for running, FTP on the bike, critical swim speed in the pool.

YOUR TARGET RACES
Add your races with an A, B or C priority and let PaceLab place the taper. It estimates a realistic finish time from your actual progression.

PaceLab is free. Some advanced features unlock with an invitation code; nothing is sold inside the app.

PaceLab is a training tool for informational purposes. It does not replace advice from a healthcare professional.

This update fixes several issues reported since launch.

CREATING AND UPDATING YOUR PLAN
• Generating a new training plan works again in all cases.
• Trail, cycling, swimming and triathlon plans now save correctly, including brick sessions (bike → run).

TRACKING YOUR SESSIONS
• Sessions are now automatically marked as done when the matching activity is imported. No more sessions showing as missed when you actually did them.

TRAIL RACES
• Your race's elevation gain is now factored into your target time and pace calculations.
• Fixed an incorrect target time displayed on technical and alpine courses.

PROFILE AND CALIBRATION
• Saving your physiological profile after importing activities works again.
• If your profile is incomplete, your level and training volume are now estimated from your history instead of defaulting to the lowest setting.

Thanks to everyone who reported these issues.
