Tuesday morning, interval day. You’ve got your track spikes in the bag, then you glance at your wrist: Training Readiness 31, “Low”. Do you skip the session? Push through? This is the question Garmin Training Readiness tries to answer every morning, for runners, cyclists, soccer players, swimmers and anyone wearing a recent Garmin. This guide explains what the score is made of, what the ranges mean, why it sometimes looks wrong, and how athletes actually use it.
What Garmin Training Readiness is
Garmin describes it as “a score and a short message” that helps you decide how ready you are for training each day. It’s a number from 1 to 100, it shows up in the Morning Report when you first look at your watch after waking, and it keeps updating through the day as you recover, train or get stressed. It isn’t a medical reading; it’s Garmin’s estimate built from data your watch already collects.
Garmin’s fenix 8 manual lists the five levels:
| Score | Level | Garmin’s message |
|---|---|---|
| 95–100 | Prime | Best possible |
| 75–94 | High | Ready for challenges |
| 50–74 | Moderate | Good to go |
| 25–49 | Low | Time to slow down |
| 1–24 | Poor | Let your body recover |
The six things that make up the score
Garmin’s manual names the inputs. Open the Training Readiness widget and you’ll see each one rated, which is the most useful part: it tells you why the number is low.
- Sleep score (last night). How long and how well you slept, based on movement, heart rate, HRV and breathing.
- Recovery time. The hours Garmin estimates you still need after recent workouts. A long run or hard match adds a lot.
- HRV status. Your overnight heart rate variability compared with your own normal range (your baseline).
- Acute load. How much training you’ve done recently. Garmin says each workout’s effect fades over about ten days.
- Sleep history. Your sleep over the last three nights, so one good night doesn’t erase a rough week.
- Stress history. Your all-day stress readings over the last three days.
On dive-capable watches like the fenix 8 there’s a seventh input, dive history: the score is unavailable for 24 hours after a dive longer than 3 minutes and deeper than 4.6 m (15 ft). Garmin has never published how much each factor counts. Independent reviewers agree that last night’s sleep and leftover recovery from recent training move it the most, but any exact percentage you see online is a guess.
Why your score needs three weeks
HRV is personal: a “good” number for one athlete is low for another. That’s why Garmin builds your baseline from your own nights. Garmin says you’ll see a 7-day HRV average after a week of sleeping with the watch on, and after three weeks it can compare that average with your baseline. Until then, Training Readiness works with less information, so treat early scores loosely. Wear the watch to bed every night, snug enough that the sensor stays on your skin.
Why the score sometimes looks wrong
- After a race or long run, it drops hard. That’s by design: recovery time and acute load hold the score down for a day or more even if you slept well.
- Workouts you didn’t record don’t count. If you play a pickup basketball game without starting an activity, the watch mostly sees it as stress and steps rather than a workout, so acute load and recovery time miss it.
- Life stress shows up. Garmin lists poor sleep, stress, a change in activity, not eating enough and “a cocktail or two” among things that pull HRV down.
- It can’t feel your legs. A wrist sensor can’t measure sore muscles or mental fatigue. You can feel fresh with a 40, or wrecked with a 75.
- Illness and travel. A cold, jet lag or a late night will often lower HRV and sleep scores before you notice symptoms.
How athletes use it day to day
The best way to read Training Readiness is as a nudge, not an order. A simple approach many coaches suggest:
- High or Prime: a good day for the hard session you planned: intervals, a tempo run, a heavy lift, a long ride.
- Moderate: train as planned, but listen to how the warm-up feels.
- Low: consider swapping the hard session for an easy one, or moving it a day. An active recovery day fits here.
- Poor: prioritize rest, food and sleep. If it stays low for days with no obvious reason, or you feel unwell, talk to a doctor.
Look at the trend more than any single morning. One low score after a wedding means little; a slide over two weeks during heavy training is worth acting on. Pair it with how you feel and with your coach’s plan, and see our athlete recovery routine and HRV for athletes guides for what to do on the low days.
Training Readiness vs Body Battery
They sound alike but answer different questions. Body Battery is an energy gauge that drains with activity and stress and refills with rest, and it’s useful for planning your whole day. Training Readiness is about training specifically: it adds your recent workload and recovery time, so it can say “go easy” even when your Body Battery is full after a lazy Sunday that followed a hard Saturday race.
Which watches have it
Training Readiness is on Garmin’s current running and adventure watches, including the Forerunner 70, 170, 265, 570 and 970, the fenix 8 series and the vivoactive 6. Garmin’s 2026 entry Forerunners brought it down to about $250, so you no longer need a top-end watch. You don’t need a Garmin Connect+ subscription for it either: Training Readiness, HRV status, Body Battery and sleep score stay free.
Gear that helps
Prices change often. These are what we saw at the maker or a major retailer in October 2026; check the current price before you buy.
Garmin Forerunner 70
- About $250
- Up to 13 days smartwatch
- HRV status, sleep coach
Garmin Forerunner 570
- About $550
- Elevate 5 sensor, skin temperature
- Evening report with sleep need
Garmin HRM 600
- Chest strap, about $160–$170
- Heart rate + HRV to your watch
- Up to 2 months per charge
The Forerunner 70 is the cheapest way in. The Forerunner 570 adds skin temperature and an evening report that tells you how much sleep you need. Because acute load and recovery time come from your recorded workouts, a chest strap like the HRM 600 gives steadier heart rate in intervals and team sports than a wrist sensor.

Training Readiness questions
What is a good Garmin Training Readiness score?
Garmin calls 75–94 “High” (ready for challenges) and 95–100 “Prime”. Anything from 50 up is “Moderate: good to go”. What matters more is your own normal: compare today with your usual range, not with a friend’s watch.
Why is my Training Readiness low after a good night’s sleep?
Usually because of recovery time or acute load from recent hard workouts. Open the widget: if sleep is green but recovery time is red, it’s your training, not your sleep, holding the score down.
Should I skip a workout when it says Low?
Not necessarily. Many athletes keep the session but make it easier or shorter, or swap days. If you feel good in the warm-up, the plan from your coach still counts. If you feel bad and the score agrees, take the easy day.
How long until Training Readiness is accurate?
Garmin says it takes about three weeks of wearing the watch overnight to build your HRV baseline. Until then the score has less to go on.
Does Training Readiness need a subscription?
No. It’s free on compatible watches. Garmin Connect+ (about $6.99 a month) adds extras, but Training Readiness, HRV status, Body Battery and sleep score are not behind it.
