The Ambassador Program: Bring IntervalCoach to Your Club

IntervalCoach now has an ambassador program for athletes who bring it to a club, team or training group. Free Max, the club AI digest, a story on the blog, and a direct line to the founder. No follower threshold, and every application is reviewed individually.

Individual recovery curves, now fitted from every morning

IntervalCoach now estimates each athlete's recovery curve from their full history of overnight measurements, around a hundred mornings rather than the four or five the previous estimator could use, by modelling how the effects of consecutive sessions overlap. Depth is individually fitted for every athlete, the recovery rate for those whose data supports one, and the model is validated against mornings it has not seen.

How Running Power Works in IntervalCoach

Pace lies on hills and in wind. Power does not. Here is how IntervalCoach uses Stryd and Garmin running power: where the reference number comes from, how workout targets are built from it, how your running power trend is tracked, and why running fatigue is judged on a different scale than cycling.

Spotlight: Mattia, Four Weeks to Varese After a Summer That Kept Interrupting

An Italian rider whose July held the two biggest rides of his year, whose August came apart, and who has spent the last three weeks rebuilding for the Gran Fondo Tre Valli Varesine on 4 October.

運動員專訪2026年9月7日3 分鐘閱讀英文版

Spotlight: @yinuo-chen, Five Months Flat, Then Everything Moved

A Chinese rider chasing 4 W/kg whose estimated FTP sat still from March to August, and then jumped 27 watts in a fortnight. What changed was not the training. It was what the training finally asked of him.

The Coach Plan: run a whole squad without losing the athlete

IntervalCoach now works for the person behind the athletes. One roster that sorts itself by who needs you, a Monday briefing in your inbox, approvals for the whole squad in one list, and analytics that read the group honestly. Each seat covers an athlete's full subscription, so your athletes pay nothing themselves.

Spotlight: @jruddy, a 75 km Ultra Built on a Turbo Trainer

A UK multi-sport athlete heading into a 75 km trail ultra, with a build that ran through a holiday, an illness and a 35 km race rehearsal, and much of its horsepower made on a turbo trainer.

運動員專訪2026年8月29日3 分鐘閱讀英文版

Spotlight: @cichykot, the runner who lives just under threshold

A Polish runner with a 43:56 10k in June, three sub-threshold sessions a week, and a breathing sensor setting the pace. Six weeks out from his goal race, the build is stepping up.

August Update: Your Watch, Race Pages That Plan, and Rules That Stick

IntervalCoach is now on the Apple Watch. Every race page shows the demands, the finish window and the full phase timeline before you commit. You can swap or move a session from your phone. And what you write in your coaching instructions is now a rule the planner cannot overrule.

The Button That Changes Tomorrow's Workout

Every post-workout email asks how the session felt. That rating decides which workout types the coach avoids this week, and it can hold you back from a harder training phase. Here is what it does with the number, and how to give it a good one.

運動員專訪2026年8月17日4 分鐘閱讀英文版

Spotlight: Alfred, the 1:28 half marathon built on a bike commute

A year ago, Alfred had no structured endurance background to speak of. Last Saturday he ran the Tavelsjö Halvmarathon in 1:28:00, on barely 25 kilometres of running a week. The engine came from somewhere else: a bike commute of almost 28 kilometres each way.

Your Coach Is Now on Your Wrist

IntervalCoach now has an Apple Watch app: your readiness, today's workout, health metrics and training score at a glance, complications for your watch face, and planned workouts that appear in the Watch's own Workouts app automatically, ready to start.

運動員專訪2026年7月31日4 分鐘閱讀英文版

Spotlight: JiMaocc Asked for Her Weak Spots, and the Power Curve Answered

She told the coach to read her power curve, find what was missing, and make her more complete. Then she moved continents, lost her trainer, and the flat part of that curve kept going up anyway.

運動員專訪2026年7月29日5 分鐘閱讀英文版

Spotlight: Pius, an Hour on the Trainer and 300 km of Gravel

A Swiss rider who mostly trains one hour at a time, indoors, then rides 300 kilometres of gravel across a single day. How a small, consistent base powers enormous outdoor efforts.

July Update: Readiness Rebuilt, a Race Catalog, and Fitbit Support

Your readiness score is now a pure measure of how recovered you are, with every factor shown. There is a browsable catalog of real races you can adopt as your goal in one step. Google Health brings Fitbit and Pixel Watch in. Plus triathlon goals, running power, an indoor and outdoor preference, and your training inside Claude or ChatGPT.

Garmin Just Bought TrainingPeaks and TrainHeroic. What It Means for Your Training Data

A device manufacturer now owns the platform that built its reputation on working with any device. Here are the three questions that actually matter for athletes and coaches, and what I would do about my own data either way.

運動員專訪2026年7月21日3 分鐘閱讀英文版

Spotlight: Martin Trains the Way He Wants, and Lets the Plan Catch Up

A Czech rider who barely touches a prescribed workout. He rides his own club sessions and his own mountain camps, lets IntervalCoach adapt them in place, and is carrying a season-long aerobic base toward the Lawi Tour.

功能2026年7月9日4 分鐘閱讀英文版

Your Fitbit and Pixel Watch, Meet Your Coach

Google Health is now a first-class data source in IntervalCoach. Sleep, HRV, resting heart rate and more from your Fitbit, Pixel Watch or any Wear OS device flow straight into your daily readiness score, and your workouts sync to Intervals.icu automatically.

Spotlight: Djeno Points a Whole Spring at the Alpe d'Huez

A Flanders amateur who turned cycling's most famous climb into a personal deadline, and spent a spring of sweet spot and threshold work reverse-engineering the fitness for it.

Bring Your Training Into Claude, ChatGPT and Cursor

You can now connect IntervalCoach to Claude, ChatGPT or Cursor. The assistant reads the things only our engine knows, your personal recovery curves, your readiness measured against your own baseline, your adaptation signals, and combines them with the other tools already in your workflow: your calendar, Slack, email. It's built on MCP, the open standard, and it's available on the Max plan.

Spotlight: Phaidra, Building a Climber's Engine for Gatineau

A seven-hour endurance ride at the peak of her biggest week, an aerobic base rebuilt from 43 to 87, and a system being shaped for one September time trial in Gatineau.

功能2026年7月4日3 分鐘閱讀英文版

Your Readiness Score Grew Up

Readiness Score 2.0 is built on your feedback: the score now measures purely how recovered your body is, anchors once your morning data is in, and treats how you feel as a full factor. Training advice gets its own place, so a rest day reads like what it is.

功能2026年7月3日3 分鐘閱讀英文版

Your Whole Training Block, Planned for Real

Your calendar now holds real, structured workouts weeks ahead: four weeks on Pro, eight weeks on Max. Adding a session builds the actual workout instantly. And when life changes your week, the rest of the week now rebalances around it.

June Update: Android, Your Whole Ride Charted, and Clubs

IntervalCoach is now on Android. Your activity view charts the whole session with a per-ride power curve and durability. Clubs let you train with the people you ride and run with. Plus illness you can see coming, a recovery profile for everyone, Coach+ that reads the weather, and a stack of smarter-plan work.

Spotlight: @andy-mcburney Stacks Three Sports a Day for 70.3 Jones Beach

A New York triathlete who swims, rides and runs in the same day, raced two 70.3s this spring, trained through a head cold, and is now pointed at Jones Beach in September.

研究2026年6月24日5 分鐘閱讀英文版

Can you see illness coming? What the overnight data shows

The second read from our recovery data. In the days before a sick day your resting heart rate creeps up and your HRV sags, and resting heart rate is the earliest reliable sign of all. This is IntervalCoach at its best: proven textbook markers, sharpened by the signals our own athletes give us, so your coach can see an infection coming a little sooner and pace your comeback by your body, not the calendar.

功能2026年6月23日2 分鐘閱讀英文版

Your AI cycling and running coach now runs on Android too, completing the family alongside the web, iPhone and Mac apps. Full parity with the iPhone version: daily briefing, Coach+, your training plan, and the new activity charts.

Spotlight: François and 24 Hours of Le Mans on a Bike

A French rider sixty-eight days out from the 24h du Mans Vélo, with a CTL of 107 and a fitness base that has not wobbled all spring. The shape of a build aimed at riding through the night.

研究2026年6月21日6 分鐘閱讀英文版

Do fitter athletes recover faster? What our recovery curves show

This is not a one-off discovery. It is the platform doing its job: because IntervalCoach learns a recovery curve for every athlete, we can ask questions across thousands of them, and the answers flow straight back into the product. The first one surprised me. Fitness changes how hard a session hits you, not how fast you clear it.

運動員專訪2026年6月20日3 分鐘閱讀英文版

Spotlight: Kris and a Full Spring of Racing

A road racer in eastern China who spent the spring on a regional gran fondo series, with a CTL of 88 and a fitness base that has barely moved off 100 for two months. What staying race-ready actually looks like.

功能2026年6月17日5 分鐘閱讀英文版

One system that learns how you recover, and shows its work

Two questions decide most training days: am I recovered enough to go hard, and if not, when will I be? IntervalCoach now answers both from your own recovery, not a population average, and shows you exactly how it got there.

功能2026年6月16日4 分鐘閱讀英文版

Tired, or getting sick? IntervalCoach now catches it before you feel it

Your HRV tanks the same way whether you smashed yesterday's intervals or you're coming down with something. That ambiguity is exactly the wrong thing to guess at. Here is how IntervalCoach now reads the signals that training cannot fake.

運動員專訪2026年6月15日2 分鐘閱讀英文版

Spotlight: Marsl and the Seven-Hour Saturday

A German rider with a CTL in the low 80s, a self-set 350-watt FTP target, and a 200 km radmarathon he just rode in seven hours and seventeen minutes. The shape of a block that earned its race day.

運動員專訪2026年6月9日2 分鐘閱讀英文版

Spotlight: @tino-76 Is 49 and Rebuilding on His Own Terms

A masters rider who is honest about his limits: recovery is slow, long threshold efforts break him. So he trains around them, and the rebuild is working.

Coming Back From Illness Without Blowing Yourself Up

The most common way athletes set themselves back is the week they feel better. Here is the graduated return-to-training framework IntervalCoach uses, and what to watch for in the days before you are ready to push again.

運動員專訪2026年6月7日3 分鐘閱讀英文版

Spotlight: @javi Is Building a Mallorca Engine for La Purito

A Palma-based rider sitting on an engine most of us never reach: CTL in the low 80s, a Fitness Base above 80 all month. He rode the Mallorca 312 this spring, and now he is pointing the same engine at one of Europe's hardest climbing days.

功能2026年6月4日4 分鐘閱讀英文版

Race Pace Plans: A Coach For The Day Itself

All the training in the world doesn't matter if you go out too hard and blow up at 60%. Race Pace Plans give you a specific, goal-aware pacing strategy, a warm-up protocol, and an honest read on the day — a full plan for your A and B races, and a lighter version for C events.

功能2026年6月1日3 分鐘閱讀英文版

Introducing Clubs: Train Together on IntervalCoach

The hardest part of training isn't the workout — it's showing up, week after week. Clubs bring the people you ride and run with into IntervalCoach, so your friends keep you honest while the coach keeps each of you on your own plan: a shared feed, fair leaderboards, a weekly AI read on the group, and shared events.

A trail runner in the Algarve, three hours and 1,120 metres of climbing on a 31-degree morning, all of it pointed at a 100 km mountain ultra in late June.

Spotlight: Jos and the 100-Mile Rebound

Two days from a 100-mile gravel race, after a Merano training camp that capped a 90-day arc from CTL 50 to 83. The shape of a build that worked.

Trail running and brick workouts as first-class sports

Trail running and brick workouts (bike + run) are now first-class sports across IntervalCoach — schedule chips, dedicated catalog templates, terrain-aware race pacing for trail events, and a race-sim brick pattern that auto-fires for triathletes in their final taper.

What to Train For When You're Not Racing

Not everyone trains for a race. IntervalCoach supports nine non-race goal templates, each with its own duration, ramp rate, and phase model, so the plan still makes sense when there is no start line to count down to.

How IntervalCoach Adapts Your Workout Every Day

Your weekly plan sets the direction. A pipeline checks whether today's workout still makes sense, and reshapes it when it does not: from a full rest day to a longer warm-up for sore legs or a breathing cooldown for a rough night. It runs every morning, and again whenever new data lands during the day.
