Rucking has moved from military training into mainstream fitness, but much of the coverage runs on impressions: "everyone's doing it," "the hottest trend of 2026." This page collects the numbers that can actually be sourced and says plainly where the data runs out.
It covers retail sales data, platform trend reports, peer-reviewed research and the published calorie model, with each statistic linked to its source. If you're writing about rucking, citing this page, or just want to know whether the trend is real, start here.
For the basics of what rucking actually is, start with what is rucking?. For the trend analysis behind these numbers, see why rucking is the fitness trend of 2026.
Key rucking statistics (editor's picks)
The headline numbers, each covered in detail below:
- Weighted vest sales grew more than 50% year over year, reaching $27 million in the 12 months ending May 2025, according to Circana retail data reported by Axios.
- GORUCK's sales rose 40% in 2023, according to founder Jason McCarthy in GQ's reporting on the rucking boom. That is company growth, not a national participation rate.
- At 3.5 mph on flat pavement, the Pandolf model estimates about 363 calories per hour unloaded for a 180-pound person, about 394 with 20 pounds, and about 420 with 35 pounds.
- A 35-pound load raises that modeled example by roughly 16%, but body weight, speed, grade, terrain, and individual physiology all change the result.
- A 12-mile march under 3 hours with a 35-pound load is a common military school and badge benchmark, not a universal Army fitness standard. See the context in our rucking pace chart.
- Strava's 2025 report drew on more than 180 million users and survey responses from more than 30,000 people, and described Gen Z interest in walking, weight training, and multi-sport activity. It did not publish a rucking participation count.
- ACSM's number-one fitness trend for 2026 was wearable technology. Rucking was not a named top-ten category in the official ACSM list, so ACSM should not be cited as direct evidence of rucking growth.

Growth and market statistics
Weighted vest and ruck gear sales are the cleanest growth signal we have. Circana's retail tracking, reported by Axios in June 2025, showed weighted vest sales up more than 50% year over year to $27 million in the 12 months ending May 2025.
GORUCK's reported 40% sales jump in 2023 is one brand-level signal. GQ reported the increase, citing founder Jason McCarthy, but the article does not provide a category-wide sales denominator or a national participant count. GORUCK maintains a substantial current event calendar; this page does not attach a total to it without a dated source that shows the count.
Media attention is broad, but it is not participation data. Rucking has appeared in general-interest and fitness coverage, which we break down in our 2026 trend analysis. The official ACSM 2026 list names wearable technology as its top trend; it does not list rucking as a standalone top-ten category.
Search interest can be measured in Google Trends, but this page does not publish a trendline because we do not have a saved, reproducible export attached to the current revision. Media coverage alone cannot establish the slope.
Who is rucking: demographic statistics
Women are at the center of the current wave. Axios framed its reporting on the Circana data around women in midlife, with experts linking the trend to bone-density and longevity messaging around menopause. The Circana figure itself covers all weighted-vest sales, not sales to women specifically. (The science is more nuanced than the marketing; see the research section below.)
Gen Z activity patterns are adjacent to rucking, not a direct rucking count. Strava's 2025 Year in Sport report, drawing on more than 180 million users and a survey of more than 30,000 people, highlighted Gen Z interest in walking, weight training, and multi-sport variety. Rucking combines walking and external load, but the report does not say how many Gen Z users ruck.
The military pipeline still matters. Rucking's standards, terminology, and a large share of its community come from military training culture. The 12-mile march in under 3 hours with a 35-lb load, used by Army badge courses and schools, is the benchmark people cite most often; our pace chart breaks down what that pace actually feels like at every fitness level.
Calorie burn statistics
These numbers come from the Pandolf load-carriage equation, the military research standard for predicting energy expenditure under load, which powers our calorie calculator. Full math in our Pandolf equation guide.
| Scenario (180-lb person, flat ground) | Calories per hour |
|---|---|
| Walking 3.5 mph, no load | ~363 |
| Rucking 3.5 mph, 20-lb pack | ~394 |
| Rucking 3.5 mph, 35-lb pack | ~420 |
| Walking 3.5 mph, no load, 5% grade | ~555 |
| Rucking 3.5 mph, 30-lb pack, 5% grade | ~635 |
What the table shows:
- Grade matters far more than load. A 20-lb pack adds about 9% on flat ground, while a 5% grade adds about half again even with no pack. Load and grade together produce the biggest numbers.
- There is no honest universal calories-per-hour range. Body weight, load, speed, terrain, grade, and individual physiology all move the estimate. Use the calculator with your inputs.
- Running often burns more per minute, but recovery is individual. Do not assume rucking is automatically easier to recover from at a heavy load or high weekly volume. Full comparison in rucking vs running for weight loss.

What the research actually shows
The 2025 research on weighted vests is mixed, and rucking's real benefits hold up without inflating them.
The INVEST trial (Beavers et al., Wake Forest, 2025): a 12-month randomized controlled trial in 150 older adults losing weight found that wearing a weighted vest about seven hours a day did not prevent the hip bone loss that accompanied dieting, and neither did supervised resistance training. The bone-density claims in weighted vest marketing are ahead of the evidence. NPR's fact-check covers the gap between the claims and the data.
Other findings worth knowing:
- Weight-regain pilot signal. A small 2025 pilot followed 18 older adults with obesity and osteoarthritis. The nine-person vest group regained less weight than the nine-person diet-only group, but the between-group result was not statistically significant. The authors described it as a signal requiring larger studies, not proof of protection. Read the PubMed abstract.
- Load progression and injury. No universal 10% rule has been validated for recreational rucking. Change one variable at a time, monitor symptoms and gait, and use how heavy should your ruck be for a conservative planning process.
- Mechanical loading and bone, properly framed. Adding a vest or pack raises the force through your skeleton roughly in proportion to the weight added, which is a real but modest stimulus compared with jumping or heavy lifting. That helps explain why study results are mixed. Our deep dive: weighted vests and bone density research.
The defensible case for rucking is narrower than the marketing version: added load raises modeled energy cost at the same pace and creates a different training demand from unloaded walking. Injury risk, recovery cost, strength gain, and long-term outcomes depend on dose and individual context.
Community and event statistics
- GORUCK maintains an active calendar of organized challenges and city events. The calendar establishes breadth, but the current page does not publish the 1,000-per-year and 10,000-lifetime figures previously repeated here.
- Ruck clubs provide a visible community layer. Use our ruck club finder to check actual listings, or read how to start a ruck club if your area does not have one. We do not label clubs the fastest-growing layer without a comparative dataset.
- Memorial and charity rucks draw some of the sport's most committed participants, with events like Boston's Tough Ruck drawing people who train for months for a 26.2-mile carry.

Frequently asked questions
No authoritative national participation count is publicly available. Brand sales, app users, event calendars, search interest, and weighted-vest retail sales are useful signals, but none is a complete count of people who ruck.
Axios reported Circana data showing sales above $27 million in the 12 months ending May 2025, more than 50% higher year over year. That figure covers weighted vests, not every rucksack, plate, event, or informal rucker.
There is no single number. For a 180-pound person at 3.5 mph on flat pavement, our implementation of the published Pandolf equation estimates about 363 calories unloaded, 394 with 20 pounds, and 420 with 35 pounds. These are model estimates, not direct measurements.
No broad claim is justified. A 2025 randomized trial in older adults undergoing weight loss found that neither daily vest use nor its resistance-training condition prevented hip bone loss. Other populations, exercise programs, and outcomes may differ.
Not as a named category. ACSM's official number-one trend for 2026 was wearable technology. Rucking has received substantial media attention, but that should not be presented as an ACSM ranking.
