Yes, Garmin has a rucking mode, but only on some watches. The Rucking activity arrived in Garmin's May 2025 feature update, and Garmin's own pages name its latest tactix, Instinct, Enduro, and fēnix models as compatible. You enter your pack weight before you start, and the watch records GPS, pace, heart rate, and elevation as usual. What Garmin hasn't documented is how that pack weight changes your calorie number, and carrying 2 kilograms (4.4 pounds) or more switches off VO2 max recording for the session.
That's a real step forward from logging rucks as hikes, and for many Garmin owners it's enough. Here's exactly what the rucking profile does, what it leaves out, and what to do if your watch doesn't have it. Disclosure: we make Ruckaroo, a rucking app that also runs on Garmin watches through Connect IQ, so we'll keep Garmin's facts and ours clearly separated.
Which Garmin Watches Have a Rucking Activity?
Garmin announced the Rucking activity on May 22, 2025, as part of a feature update for "select smartwatches." Its press release describes Rucking as a weighted-hiking activity that lets you manually enter your pack weight, and it introduced a separate Pack Weight feature you can add to running, hiking, and walking. For the device-by-device list, the release points to Garmin's software compatibility pages rather than naming models.
Garmin's own blog post "What is rucking? Why should you ruck with Garmin?" (May 2025) is more specific: rucking is available on the latest tactix, Instinct, Enduro, and fēnix watches. Garmin's fēnix 9 owner's manual includes a "Going Rucking" section, so the profile carries forward on the newest flagship too. Reviewers have also reported the activity on some newer Forerunner and Venu models, but we couldn't confirm a complete list on Garmin's own pages, so check your watch's manual or Garmin's compatibility list before you buy for this feature.
Quick check: on your watch, open Activities and look under Outdoor for Rucking. If it isn't there, your firmware or model doesn't have it yet.
How to Start a Ruck on a Garmin Watch
According to Garmin's fēnix 9 manual, the flow is simple:
- From the watch face, open Activities > Outdoor > Rucking.
- The first time, enter your pack weight. After that, change it under Pack Weight > Edit Weight.
- Optionally set a training target. The Target Calculator works with time, distance, pace, calories, and pack weight.
- If you set a target, the watch can add return routing to bring you back to your start, including a turnaround at the halfway point.
- Start the timer, ruck, and save the activity when you finish.
Garmin also suggests adding Rucking as a favorite activity in your watch settings so it sits near the top of the list. Weigh your pack rather than guessing; our guide to how to weight your ruck has easy ways to do it at home.
What Garmin's Rucking Mode Tracks
Under load, the profile records the same core data as a hike or walk: GPS route, distance, pace, heart rate, and elevation. The addition is the pack weight itself, which travels with the activity into Garmin Connect. Garmin says you can review your rucks there to see how pack weight affects your training over time, which is genuinely useful for anyone following a progression plan like the one in how much weight to ruck with.
| Metric | Garmin Rucking profile | Source |
|---|---|---|
| Pack weight entry | Yes, set before the ruck and editable | Garmin manual |
| GPS, pace, heart rate, elevation | Yes, as in other outdoor activities | Garmin press release |
| Targets and return routing | Yes, including a calories target | Garmin manual |
| VO2 max | Not recorded with 2 kg (4.4 lb) or more | Garmin blog |
| How load changes calories | Not documented on Garmin's pages | (see below) |
| Terrain surface (sand, gravel, trail) | Not mentioned on Garmin's pages | (see below) |
What It Doesn't Do (Yet)
It doesn't explain the calorie math
Garmin's press release says the rucking activity helps the watch track pace, heart rate, and calories more accurately under load. But neither the release, the blog post, nor the manual explains how pack weight enters the calorie estimate. In fact, Garmin's blog points readers to a Connect IQ data field if they want to see rucking calories on the watch. Heart rate rises when you carry weight, so a heart-rate-driven estimate catches part of the extra work either way.
One independent outlet, the5krunner, reported in August 2026 that the update arriving alongside the fēnix 9 adds a separate breakout of the extra calories from pack weight, lets you change pack weight mid-ruck, and allows rucking as a multisport leg, with the update reaching the fēnix 8, Enduro 3, tactix 8, and Forerunner 970. We hadn't seen Garmin publish those details on the pages we checked, so treat them as reported, not confirmed. If your watch shows a pack-weight calorie breakout, you have that update.
VO2 max goes quiet
Garmin's blog is explicit: carry 2 kilograms (4.4 pounds) or more and the watch won't record VO2 max for that activity. Garmin's press release frames this as a feature, saying pack weight keeps your VO2 max estimate from being "negatively affected," since a loaded walk would otherwise look like poor fitness. It's the right call, but it means rucks don't feed that number. If VO2 max is your main metric, keep a few unloaded runs or walks in your week; our post on rucking and VO2 max explains how loaded walking still builds aerobic fitness.
No surface or ruck-specific effort score
Load-carriage research has long shown that surface matters: sand and loose gravel cost far more energy than pavement at the same pace and load. We found nothing on Garmin's pages about modeling terrain type in the rucking profile, and there's no single ruck-specific effort score that combines load, distance, pace, and grade. Garmin's general training metrics still apply, but they weren't built around carried weight.
No Rucking Profile on Your Garmin? Your Options
- Record it as Hike or Walk. You still get route, pace, heart rate, and elevation. Garmin's Pack Weight feature may be available for these activities on watches that support it, even without the Rucking profile.
- Relabel it in Garmin Connect. Users on Garmin's forums report editing a hike's activity type to Rucking in Garmin Connect afterward and adding pack weight there. It keeps your history tidy, though it won't change what the watch measured during the walk.
- Add a Connect IQ app. Connect IQ apps run their own activity on your watch and can treat pack weight as a core input instead of a label.
Using a Rucking App on Your Garmin
This is where we come in, so here's what Ruckaroo's Garmin Connect IQ app does, in our own words. Your ruck is recorded on the watch and synced through your own Garmin account into the Ruckaroo app on your phone, where the load does the heavy lifting:
| Factor | Garmin Rucking profile | Ruckaroo on Garmin |
|---|---|---|
| Pack weight | Entered and logged | Core input to calories and score |
| Calorie model | Not documented by Garmin | Pandolf load-carriage equation blended with heart rate |
| Terrain | Not mentioned | Paved, trail, gravel, and sand resistance factors |
| Hills | Elevation gain | Load-adjusted uphill and downhill cost |
| Effort score | General Garmin training metrics | Ruck Score, 0-100 |
| Cost | Included on compatible watches | Paid subscription |
The Ruck Score rolls your load, distance, pace, and terrain into a single 0-100 number built on the U.S. Army's load-carriage research, so you can compare a short heavy ruck to a long light one. Ruckaroo also runs on iPhone and Apple Watch and on Android and Wear OS, so your history follows you if you ever switch watches.
The fair summary: if you own a recent fēnix, tactix, Enduro, or Instinct and mostly want your rucks labeled with the right weight, Garmin's built-in profile is a solid, free starting point. If you want calories and effort that are driven by the load, a dedicated rucking app adds what Garmin hasn't documented.

Frequently Asked Questions
Does Garmin have a rucking mode?
Yes, on some watches. Garmin added a Rucking activity in its May 2025 feature update. Garmin's blog lists its latest tactix, Instinct, Enduro, and fēnix watches as compatible, and the fēnix 9 manual includes it. Look under Activities, then Outdoor, to see whether your watch has it.
Does Garmin count pack weight in calories?
Garmin says the rucking activity helps track calories more accurately under load, but it doesn't publish how pack weight enters the calculation. An August 2026 report says newer firmware breaks out the extra calories from pack weight separately; Garmin hadn't documented that on the pages we checked.
Why did my VO2 max stop updating when I ruck?
Garmin turns off VO2 max recording when you carry 2 kilograms (4.4 pounds) or more, so a slow loaded walk doesn't drag your estimate down. Your VO2 max will keep updating from your unloaded runs and walks.
Can I add rucking to an older Garmin watch?
Not natively if the profile hasn't come to your model. You can record rucks as Hike or Walk, relabel them as Rucking in Garmin Connect afterward (users report this works), or install a rucking app from Connect IQ.
Is Garmin's rucking mode enough on its own?
For logging rucks with the right pack weight, yes. If you want calories driven by load, terrain, and grade, or one effort score to track progress, a dedicated rucking app fills in what Garmin hasn't documented.
