Group sessions, planned for what they are

You can now put a club ride, a running group or a Hyrox class on your calendar as a group session. Pick "Add group session" on the calendar, in your training plan or in a club, say how long it is and how hard it usually gets, and your coach plans the week around it. An easy club ride counts as endurance, so your two hard sessions stay yours to place. A hard one counts as one of your hard days, and the day before it stays easy. Either way its load comes off your weekly total, you can attach the route file, and finishing an easy group ride is analysed as the endurance session it was.

Your readiness, read from your own body

Your readiness score now moves further with how you actually slept and recovered: a morning with clearly lower HRV and a higher resting heart rate can read red, and a morning when everything is better than usual reads near the top. It can also call a rest day without a recovery score from your watch. A red readiness score makes today a rest day, and HRV well below your usual level together with a raised resting heart rate makes it an easy recovery session. New athletes get a first score after one week of wearing their watch, shown as "Learning your normal" until the app knows your baseline, and it doesn't change your training until then. A check-in you answer on Intervals.icu now counts toward your score too.

Pause instead of cancel

Cancelling on the website now starts with a choice. On a monthly plan you can pause for one, two or three months: billing stops, you keep what you already paid for, and your plan comes back by itself when the pause ends, or sooner with Resume now. You can also step down from Max to Pro or switch to yearly billing. A pause comes with an email listing the dates and a reminder a week before billing restarts, and Settings has a Keep my subscription button if you change your mind after cancelling.

Planning and your calendar

A workout you build in TrainNow now replaces the session your plan had on that day, and TrainNow opens on the time your schedule gives you that day. You can set the start time of a planned session on its own page, so your forecast, clothing advice and fuelling match that hour. Coaching instructions can set a minimum warm-up, and changes you make to them through Coach+ take effect straight away. If you switch power meters, running power pods or between a chest strap and a wrist sensor, you can mark the day in Settings → Training, so readings from the old sensor stop skewing your targets and analysis. Your dashboard now tells you when the FTP your sessions use sits below what you've been riding. Cycling steps with a cadence carry it in the step name ("Threshold 90rpm") so every head unit shows it. Your training availability has moved to the top of Settings → Training. Rebuild has a new option to clear everything IntervalCoach added.

Coach+

Coach+ now leaves your calendar alone when you tell it not to change something, and telling it you have a fever or are on holiday no longer moves your plan until you say what you want done. It asks which session you mean when a day holds two, builds strength sessions with your own sets and reps, finds sessions by the name you recorded them under, compares a run or ride with sessions of a similar distance, uses your own location for the weather, and can remove a goal that isn't a race. Tapping a finished-workout notification no longer uses one of your monthly messages.

Bug fixes & reliability

Several fixes went into your plan around races. The taper now starts from the fitness your plan builds, a race on your calendar always gets its taper and race week, and after race day the plan moves straight on to your next A or B race. Sessions you ruled out, such as sweet spot or threshold, no longer come back through a race-pace label or the load fit, and a recovery week stays easy. Your first week now trains the sport you signed up for. Post-workout analyses arrive promptly again after two days of delays and a few missed ones, which have since been written. Adding a race now works with target times like 3h30min and on an iPhone set to 12-hour time. Planned rides keep their warm-up and cool-down ramps on the way to MyWhoosh and Zwift, and indoor races no longer get a wind forecast.

In the iOS & Mac apps

Race courses reached the apps: a race shows its course profile and climbs, and you can download the GPX. The app also starts faster.

Race Recon: your race course, read into your training

Attach a GPX or FIT course to any race, or import a recorded Intervals.icu route, and IntervalCoach reads its elevation, climbs and terrain. The race page shows your preparation priorities based on your recent performance, and workouts that suit the course get a small preference within your current phase. You can also turn on surface analysis to see paved, gravel and unpaved sections. Wind forecasts mark the headwind, tailwind and crosswind stretches, with wind shown in Beaufort and a labelled arrow on the route map. Pace plans for A and B races now give you a target normalized power or pace, an hour-by-hour plan and a ceiling for the first hour, and they account for how your own long sessions usually fade. Every race also gets a fuelling plan sized to its real length. You can share a race and its course with your club, and members can get an email or push notification. Read the full story on the blog.

Find races near you

The events page can now search around a town or your location, with a radius from 25 to 250 km. It shows how far away each race starts. You can filter with one tap by distance (10K, half marathon, marathon, or distance bands for cycling, trail and triathlon), by date, by course profile, and by one-day or multi-day events, and you can leave out pro races. A marathon that also has a half now appears when you search for a half marathon.

Records, story cards and a fuller activity page

Personal records are rolling out to everyone on Pro and Max. When a ride or run beats your best power for a duration or your fastest time over a distance, the analysis email says so. It also includes a story card you can share straight to Instagram, and season bests count as well. Races get their own story card, with your route drawn faintly behind the numbers and the first and last kilometre left out for privacy. On the activity page, outdoor sessions now show a route profile with every climb and your time, power, heart rate and VAM on it. Runs and walks get per-kilometre or per-mile splits. A new time-in-zone view compares the time you spent in each zone with the time the session asked for, and it works for power, pace and heart rate.

Readiness, recovery and wearables

Your readiness score has been recalibrated so it sits closer to what Whoop, Oura and similar devices show for the same night. A normal morning now reads about 70 instead of 80, and green still starts at 67. Sleep now uses your device's sleep score when it provides one, and HRV, resting heart rate and sleep are measured against your 30-day baseline. Whoop can now also share the workouts it records on its own. If you connected Whoop earlier, use the Reconnect button in Settings. The new recovery mode, under Settings → Coach, pauses your plan and training emails for a period when you are recovering rather than training. Turning it off restores your previous settings.

Smarter planning

When your power profile shows a clear weak spot, the coach now offers to make it a focus for the block. A new beta setting spots a weeks-long dip, where your power keeps falling while your HRV or resting heart rate stays off, and holds your load easy until that turns around. Fitness tests are now scheduled for athletes at a much lower fitness level, so if you train a few hours a week, expect a ramp, time trial or CSS test. New athletes whose history hasn't synced yet get a heart-rate-based starter week. Hard days are spaced properly around sessions already on your calendar, including in non-English languages. Switching to heart rate, pace or power now converts your upcoming sessions too. Coaching instructions can set a minimum cadence, and races more than four weeks out are taken into account while your plan is written.

Coach+ and the iOS & Mac apps

Coach+ can now change or delete the exact race you mean, including C races. It can rewrite your coaching instructions once you agree on a new version, and it sees when you've marked yourself sick. If you set it to talk changes through first, it waits cleanly for your yes. A day you clear stays clear. On iPhone, new controls for Control Center, the Lock Screen and the Action Button start your check-in, open Train Now or show today's readiness. Siri now answers in your language, and on iOS 27 you can ask Siri for a workout and it lands on today's calendar. Long-press Today's Plan to move or delete a session. On Mac, rides and planned sessions open on a fuller two-column page, and runs and walks show splits. On both, the Daily Outlook updates when your plan changes during the day.

On the blog

This week we published Race Recon: your race course, read into your training and Your sessions are now pitched to your own level, one energy system at a time. We also added three guides to how AI coaching works: for endurance athletes, for runners and for triathletes.

Full changelog with all the details: https://www.intervalcoach.app/changelog
As always, let me know if you run into any issues or have feedback!

A race entry tells you the distance and the total climbing. Race Recon reads the course itself, so your training and your race day are planned around where the climbs actually are.
Turn it on: add or edit a race in Calendar or Training Plan, then attach a GPX or FIT file or import a route you have ridden on Intervals.icu. Race Recon is on Pro and Max.

What you get

• The elevation profile and every sustained climb, with its length, height gain and gradient
• How long each climb takes you, estimated at your own threshold, so your interval sessions lean towards the lengths your course demands
• On race day, the course split into climbs, descents and flats, each with a power or pace target and a carbohydrate and fluid budget
• Share the race to the community catalog and, once it is approved, the course goes with it for the next athlete preparing for the same start line
