Garmin Triathlon Coach: Setup, Watches and Training Plans
Garmin Triathlon Coach is Garmin’s free, adaptive triathlon plan inside the Garmin Connect app. You pick a race, tell it how much you swim, ride and run now, and it sends swim, bike, run and optional strength workouts to your watch, adjusting them to your recovery data. It runs on a short list of recent watches, and it plans for you rather than with you: you set preferences, the plan decides the sessions.
Quick answer
- What it is: an adaptive plan for sprint, Olympic and half distance triathlons (or custom distances), 6 to 52 weeks long, with swim workouts, two-a-days, bike-run bricks and optional strength.
- Price: free in Garmin Connect with a compatible device.
- Watches: fēnix 8, fēnix 9 and fēnix E, Forerunner 570 and 970, Enduro 3 and 4, Venu 4 and Venu X1, quatix 8, tactix 8, D2 Mach 2 and D2 Air X15.
- Set up: Garmin Connect app > More > Training & Planning > Garmin Coach Plans > Triathlon.
- Needs: heart rate and power data (a power meter or a smart trainer for the bike).
- Can’t do: move a single workout to another day; the plan adapts instead.

What Garmin Triathlon Coach does
Garmin built Triathlon Coach on its Run Coach and Cycling Coach programs, so the core is the same: workouts are picked day by day from your training load, sleep and recovery, and the plan pushes harder when you’re absorbing the work and backs off when you’re not. On top of that it adds what a triathlete needs:
- Swim workouts. Mostly freestyle, with intensities called recovery, easy, hard, very hard, all out and descending. You set your comfortable swim distance, and some sessions use a kickboard, pull buoy or paddles (paddles only for higher-volume swimmers).
- Two-a-days. Two workouts in one day, always in different sports, such as a morning swim and an evening ride.
- Brick workouts. A ride followed straight away by a run, about every other week, usually easy and endurance-focused, a bit harder in specific phases.
- Optional strength. Gym and bodyweight or bodyweight-only sessions that ramp up early and ease off towards race day.
- Targets. Runs by heart rate, pace, or Auto (heart rate for easy work, pace for hard work). Rides by heart rate, power, or Auto (heart rate for easy, power for hard).
The supported distances are sprint (750 m / 20 km / 5 km), Olympic (1500 m / 40 km / 10 km) and half distance (1.9 km / 90 km / 21.1 km). A custom race can be anything from 300 to 2500 m swimming, 7 to 120 km cycling and 2 to 32 km running. If you have no race, the Improve Fitness option keeps you on general triathlon training.
How to set up a Garmin triathlon training plan
- Open the Garmin Connect app and tap More (bottom right), or open Garmin Connect on the web.
- Go to Training & Planning > Garmin Coach Plans and select Triathlon. Accept the terms.
- Choose a training focus: Train for an Event, Achieve a Milestone or Improve Fitness.
- Enter your current average weekly swimming, cycling and running, choose the distance and set your goals.
- Pick one of the recommended plans.
- Set your schedule: 6 or 7 days you can train (an unchecked day becomes a rest day), 1 to 2 days for the long run and long ride, 1 to 2 swim days, your swim distance range, and whether you want strength.
- Select your race (its date ends the plan) or an end date.
The workouts then sync to your watch. Add the Garmin Coach glance to see today’s session; with Workout Prompts on, starting a compatible activity offers you today’s workout.
Which watches get Triathlon Coach
Garmin’s compatibility list, checked on 5 November 2026:
- fēnix: fēnix 8 series, fēnix 9 series, fēnix E
- Forerunner: Forerunner 570, Forerunner 970
- Enduro: Enduro 3, Enduro 4
- Venu: Venu 4, Venu X1
- quatix, tactix, D2: quatix 8 series, tactix 8 series, D2 Mach 2 series, D2 Air X15
Popular triathlon watches such as the Forerunner 265, Forerunner 965 and fēnix 7 are not on the list. On those you still have three options:
- Garmin’s self-guided triathlon plans. Prebuilt 12-week sprint and Olympic plans on the Garmin Connect website. You can reschedule workouts, but only the run and bike sessions are sent to the watch, and the plan doesn’t adapt.
- Build the sessions yourself in the Garmin Connect workout builder: how to create a workout in Garmin Connect covers run, bike, pool swim and strength workouts, sending and scheduling.
- A plan from an app that pushes to Garmin Connect, which reaches any Garmin that runs structured workouts from the calendar. More on that below.
What you can change, and what you can’t
In the plan’s settings (three dots in the app, the gear icon on the web) you can edit your available days, long workout days, swim days and swim distance, run and bike target types, strength workouts, training goal and event details. You can also pause the plan, for example when you’re ill.
Three things are fixed:
- Single workouts can’t be rescheduled. Garmin says this is by design: when you miss a session, the plan adapts.
- The end date and distance can’t be changed. Deleting the event deletes the whole plan.
- Swim days are a preference. After poor sleep or travel the plan may swap out a swim on your chosen day.
Garmin Triathlon Coach or a plan pushed to Garmin Connect
| Garmin Triathlon Coach | TextFit | |
|---|---|---|
| Price | Free with a compatible Garmin | 14 days free, then $14.99/month or $99.99/year |
| Watches | The list above | Any Garmin that runs workouts from the Garmin Connect calendar, and Apple Watch |
| Distances | Sprint, Olympic, half, custom up to 2500 m / 120 km / 32 km | Sprint, Olympic, half and full distance, or general fitness |
| Swim targets | Intensity words (easy, hard, very hard) | Pace per 100 m from your CSS |
| Strength | Optional gym or bodyweight | Optional, gym or home, in the same week |
| Moving a session | Not possible, the plan adapts | Ask the coach: “move Saturday’s long ride to Sunday” |
Garmin Triathlon Coach is the natural start if you own a listed watch and want a plan that runs itself. A coach that plans with you suits you better when your week changes a lot, when you want swim targets in seconds per 100 m, or when your watch isn’t on Garmin’s list. Garmin Coach and more paid apps sit side by side in the triathlon training apps comparison.
How TextFit plans a triathlon week on your Garmin
TextFit is an AI coach for iPhone and Android that plans swim, bike, run and strength as one week. You tell it your race and date, the days and time you have, and your current fitness in your own words (“10 km in 45 minutes, FTP 230, 100 m in about 1:50”); it reads your threshold pace, FTP and CSS from that. A sport without a known threshold gets a test first: a 400 m + 200 m CSS swim, an FTP ramp or a 30-minute run (a sport you’re new to trains by effort for 4 weeks before its test).
Every week follows the same rules, checked in code:
- Hard days are counted across sports. At most 2 a week (3 above 8 sessions), never on consecutive days, so a hard swim on Tuesday and bike intervals on Wednesday can’t happen.
- A long weekend. A long ride and a long run on Saturday and Sunday, the run usually after the ride and shorter than a standalone long run. Together they count as one hard day.
- About 80 % easy across all three sports.
- Strength 1 to 2 times a week, after a key session or on an easy day, never the day before a key or long workout.
- At most 2 sessions a day: easy with easy, easy with strength, or a key session followed by strength.
- Volume up by no more than 10 % a week, a recovery week with 30 to 40 % less every 4th week, and a 2-week taper before the race.
For what the targets look like, see triathlon interval training for the intensity bands and bricks, and the Olympic distance example week on the AI triathlon coach page.
What lands on your Garmin
Connect Garmin Connect once and the next 7 days of the plan are pushed to your Garmin Connect calendar as structured workouts: runs with your paces, rides with your watts, pool swims with your pace per 100 m and send-offs, strength sessions with each exercise’s sets, reps and weight. They sync to your watch or Edge like a workout you built yourself, with the same step screens and alerts. When the plan changes, only the changed workouts are sent again.
Your activities, HRV, resting heart rate and sleep come back from Garmin. The coach compares each workout with the plan, tracks Fitness, Fatigue and Form from your training load, and gives a 🟢🟡🔴 recovery verdict with a one-tap “Ease today”. When the pool is closed or work runs late, one message in the coach chat changes the week, every change shown with Undo. Details on TextFit with Garmin and how the coach builds a week.
FAQ
Is Garmin Triathlon Coach free?
Yes. Garmin Coach plans are free in the Garmin Connect app with a compatible watch. A Garmin Connect+ subscription adds coaching videos and educational content, but the plan itself doesn’t need it.
Does Garmin Triathlon Coach work on the Forerunner 265 or fēnix 7?
Not as of 5 November 2026: Garmin’s list covers the fēnix 8, fēnix 9, fēnix E, Forerunner 570 and 970, Enduro 3 and 4, Venu 4, Venu X1, quatix 8, tactix 8 and D2 Mach 2 / Air X15. On other watches you can follow a self-guided plan from the Garmin Connect website (run and bike workouts go to the watch) or use an app that pushes all sessions to Garmin Connect.
Can Garmin Triathlon Coach train me for a full Ironman?
Its race distances are sprint, Olympic and half distance, and a custom race can go up to 2500 m of swimming, 120 km of cycling and 32 km of running, which is short of a full-distance race. TextFit plans full-distance triathlons as well.
Do I need a power meter for Garmin Triathlon Coach?
Garmin lists heart rate data and power data as requirements, with power from a power meter or an indoor trainer. Heart rate can come from the watch’s optical sensor or a chest strap.
Can I move a Garmin Triathlon Coach workout to another day?
No. Triathlon Coach doesn’t allow rescheduling; when you miss a workout, the plan adjusts the next ones. You can change your available days, long workout days and swim days in the plan settings.
Can I use Garmin Triathlon Coach and TextFit together?
Follow one plan at a time. Two plans on one calendar give you two sets of hard sessions in the same week. If you switch to TextFit, quit or pause the Garmin plan first; your completed Garmin activities still count, because the coach reads them back from Garmin Connect.
