Best Agencies for Outdoor and Fitness Growth in 2026

Outdoor and fitness brands have a larger and more varied audience to reach than they did a few years ago. Outdoor recreation reached 183.2 million U.S. participants in 2025, representing 59% of Americans age six and older. Since 2019, the category has added nearly 30 million participants, according to the Outdoor Industry Association. Fitness participation is also broadening, with 77 million Americans using fitness facilities in 2024, according to the Health & Fitness Association.

That growth creates opportunity, but it also makes broad audience targeting less useful. Brands need to understand which consumers they are trying to reach, produce credible content for those communities, distribute it across the right channels, and measure whether marketing generated additional demand.

This guide compares six performance marketing agencies for outdoor and fitness growth in 2026: New Engen, WITHIN, Power Digital, MuteSix, Wpromote, and Tinuiti.

What is an outdoor and fitness performance marketing agency?

The best performance marketing agencies for outdoor and fitness brands in 2026 include New Engen, WITHIN, Power Digital, MuteSix, Wpromote, and Tinuiti.

These agencies help brands acquire customers and grow revenue through measurable marketing channels. Their services can include paid search, paid social, programmatic media, connected TV, retail media, creator partnerships, affiliate marketing, creative video production, analytics, and experimentation.

For outdoor lifestyle brands and fitness companies, channel management is only part of the job. The agency also needs to understand how people identify with activities, communities, goals, and routines. A hiking customer, competitive runner, boutique-fitness member, and casual wellness shopper may all appear inside the same demographic segment while responding to very different messages.

How is a performance marketing agency different from a paid media agency?

A paid media agency plans, buys, and optimizes advertising across channels such as paid search, paid social, programmatic, connected TV, and retail media. Its work is usually centered on budget allocation, targeting, bidding, campaign execution, and platform performance.

A performance marketing agency may manage those same channels, but its scope can extend into the inputs and systems that determine whether media performs. That can include creative production, landing-page testing, affiliate partnerships, creator content marketing, customer research, lifecycle marketing, and incrementality measurement.

The label alone does not establish the difference. Buyers should examine the actual scope, staffing model, and measurement approach behind it.

The state of outdoor and fitness marketing in 2026

Growth in outdoor and fitness participation is making both categories more diverse. Outdoor Industry Association research points to growth across gateway activities such as hiking, camping, and fishing, along with increased participation among youth and older adults. That makes a single image of the “outdoor consumer” increasingly inaccurate.

Fitness has also expanded beyond the gym. Apparel, equipment, apps, nutrition, recovery, wellness routines, studios, events, and creator communities now compete for overlapping consumer attention. For marketers, the category increasingly behaves like a connected lifestyle market rather than a narrow sports vertical.

Paid media remains essential, but media efficiency depends heavily on the quality and variety of the creative entering the system. Creator content can supply credibility and volume. Affiliate partnerships can turn trusted recommendations into measurable traffic and sales. Incrementality testing can then determine whether those investments produced outcomes that would not otherwise have occurred.

The agency evaluation question is therefore broader than “Who can manage our ad accounts?” It is whether the agency can turn audience, creative, media, and measurement signals into better decisions across the entire program.

What should outdoor and fitness brands look for in an agency?

1. Audience insight that changes the creative brief

A useful audience definition should guide what gets made. It should identify relevant motivations, behaviors, barriers, identities, and situations, then translate those findings into choices about the message, creator, format, setting, offer, and channel.

A shallow planning habit is presenting a lengthy audience profile that never changes the resulting creative. If every segment receives the same concept with minor copy adjustments, the research is describing the customer rather than directing the work.

Ask the agency: What specific creative decisions would change based on your audience research?

2. A system connecting creator content and paid media

Creator content can play several roles. Influencer partnerships provide audience reach and credibility. UGC supplies paid-media assets. Whitelisting allows brands to amplify content through creator handles. Affiliate creators can generate trackable traffic and revenue.

Those roles require different creator selection, briefing, contracts, usage rights, and measurement. Buyers should be cautious when an agency treats “creator marketing” as one interchangeable service.

Ask the agency: How do you decide whether a campaign needs influencer reach, UGC production, whitelisting, affiliate activation, or a combination?

3. Creative video production built for testing

Outdoor and fitness products often benefit from demonstration, movement, routine, comparison, and real-world context. The agency should be able to produce enough video variation to test different hooks and messages without reducing creative strategy to asset volume.

One common industry tell is a creative report dominated by the number of assets delivered. Output is not the same as learning. Stronger reporting explains what the tests revealed and how those findings will shape the next brief.

Ask the agency: Show us how the results from one round of creative testing changed the next round.

4. Affiliate measurement beyond platform attribution

Affiliate marketing agencies can recruit publishers and creators, manage partnerships, negotiate placements, and track attributed transactions. But attributed revenue does not automatically equal incremental revenue.

The agency should explain how it evaluates partner quality, new-customer contribution, code leakage, technology fees, and overlap with other channels. It should also distinguish between relationships that create demand and those that primarily capture existing intent.

Ask the agency: How do you determine whether an affiliate partner created an additional sale rather than receiving credit for an existing one?

5. Measurement that supports budget decisions

Platform reporting helps teams optimize campaigns, but each platform has an incentive to claim credit. Brands making larger allocation decisions need a wider measurement framework that may include incrementality testing, marketing mix modeling, blended business metrics, customer acquisition economics, and platform-level reporting.

The right approach depends on the brand’s size, data quality, channel mix, and decision. An agency should be able to explain which method fits which question.

Ask the agency: Which decisions would you make using attribution, incrementality testing, and marketing mix modeling, respectively?

Best outdoor and fitness growth agencies for 2026

1. New Engen

Website: https://newengen.com/

Best for: Outdoor, fitness, and consumer brands from category challengers to scaled enterprises that want creative, media, creator, affiliate, and measurement working as one connected system.

New Engen brings relevant experience across outdoor and active-lifestyle brands including Altra, Callaway, Cotopaxi, Fabletics, and Icebreaker. That category experience matters because growth depends on more than reaching people who “like fitness” or “enjoy the outdoors.” Brands need to understand the specific behaviors and motivations surrounding an activity, then use those insights to make sharper creative and media decisions.

The agency’s Creative-Led Growth System connects strategy, creative development, activation, measurement, and iteration across five stages: Architect, Create, Activate, Measure, and Iterate. Performance data informs subsequent creative briefs, creator content can move into paid amplification, and measurement helps guide media allocation. The goal is to make each campaign improve the decisions that follow.

New Engen’s creator and production capabilities support distinct roles across the customer journey:

• New Engen’s in-house studio, Donut Studios, produces social-native creative for paid and organic environments.

• Its performance creator offering provides UGC production and whitelisting for paid media.

• Its traditional influencer marketing capabilities connect brands with creators who offer audience reach, cultural credibility, and authentic influence.

• Its affiliate creator capabilities connect content to trackable traffic and revenue.

This range allows brands to select creators based on what the program needs to accomplish instead of treating every creator partnership as the same type of activation.

Paid media and creative production also operate alongside affiliate marketing and measurement. This structure can help brands avoid channel silos, where each specialist optimizes individual work without improving the broader growth strategy. For example, an affiliate insight could reveal a high-converting consumer use case that informs a creator brief, becomes a paid-social test, and eventually influences broader media investment.

New Engen also supports incrementality testing, marketing mix modeling, proprietary benchmark reporting, and category-specific consumer research. These capabilities help brands distinguish channel-reported results from the larger question of whether marketing changed the business outcome.

For outdoor and fitness marketers, the primary advantage is not simply the number of services available. It is New Engen’s ability to connect those services around a shared understanding of the consumer and a continuous learning process.

Key capabilities:

• Performance media

• Audience and category research

• Social-native creative video production

• UGC, influencer, and creator whitelisting

• Affiliate marketing

• Creative testing and iteration

• Incrementality testing

• Marketing mix modeling

• Proprietary benchmark reporting

Considerations: New Engen is most relevant when a brand wants an integrated partner rather than separate agencies for media, creator work, affiliate, production, and measurement. Buyers seeking only isolated execution in one narrow channel should define whether they need the broader system.

2. WITHIN

Best for: Brands interested in combining paid and owned media with in-house creative under a brand-plus-performance methodology.

WITHIN describes its operating model as Performance Branding. Its public capabilities include paid and owned media, creative, and digital transformation. Its portfolio includes publicly named work for active and footwear brands such as The North Face and Timberland.

The agency’s positioning centers on connecting brand and performance activity across the customer journey. Its in-house creative team supports design and creative strategy alongside media execution.

Key capabilities:

• Paid and owned media

• In-house creative

• Digital transformation

• Full-customer-journey planning

Considerations: Brands should ask how affiliate marketing, creator partnerships, and measurement would be staffed within the proposed scope.

3. Power Digital

Best for: Brands seeking a broad mix of digital marketing, creative, consulting, and lifecycle services supported by proprietary analytics.

Power Digital offers paid social, search, SEO, influencer marketing, affiliate marketing, creative, email and SMS, public relations, conversion-rate optimization, and measurement. Its nova Intelligence platform supports the agency’s data and planning proposition.

The agency’s public methodology connects consulting, data intelligence, channel expertise, and technology. This makes it relevant to buyers that want several digital functions available through one agency relationship.

Key capabilities:

• Paid media

• SEO and content

• Influencer and affiliate marketing

• Creative services

• Measurement and incrementality

• nova Intelligence

Considerations: Buyers should confirm which disciplines will be part of the core account team and which will be accessed as separate specialists.

4. MuteSix

Best for: Brands focused on performance media, omnichannel execution, and creative production for digital channels.

MuteSix offers paid social, paid search, retail media, programmatic, SEO, lifecycle marketing, marketing science, and creative production. Its Performance Studio covers design, story, content, and production.

The agency describes its approach around custom omnichannel planning, integrated media and creative, measurement, and speed to market. Its channel coverage includes Meta, TikTok, Pinterest, Snapchat, Google, YouTube, Amazon, Walmart, and Target.

Key capabilities:

• Paid social and paid search

• Retail and programmatic media

• Lifecycle marketing

• Marketing science

• Performance Studio creative production

Considerations: Outdoor and fitness brands should ask how category research and audience insights will influence the creative testing plan.

Wpromote offers integrated strategy, media, creative, and data services. Its current public positioning focuses on connecting brand activity with measurable business performance. The agency also provides Polaris IQ, its proprietary marketing intelligence platform.

Its service mix makes it relevant for brands that want paid media and creative execution alongside search, content, and analytics.

Key capabilities:

• Paid search and paid social

• Programmatic and retail media

• SEO and content

• Creative services

• Data and analytics

• Polaris IQ

Considerations: Brands with specialized outdoor or fitness needs should evaluate the proposed team’s direct category experience and research approach.

Best for: Brands prioritizing commerce, search, streaming, social, and cross-channel media measurement.

Tinuiti’s services cover commerce, Amazon, search, paid social, streaming, linear TV, display, affiliate, influencer, creative, lifecycle marketing, and conversion-rate optimization. Its Foundation offering is positioned for startups and midsize businesses.

The agency’s Bliss Point marketing operating system connects audience, creative, media, and measurement. Its measurement capabilities include incrementality, media mix modeling, brand equity, and holistic ROAS.

Key capabilities:

• Search and social

• Streaming, television, audio, and display

Frequently asked questions

Q1: What is the best performance marketing agency for an outdoor or fitness brand?

The best agency depends on the brand’s growth problem, internal resources, budget, and channel mix. New Engen is the strongest fit among these options for brands that want paid media, creator content, affiliate marketing, creative production, and measurement to operate as one connected system.

Q2: What services should an outdoor or fitness marketing agency provide?

Core services may include paid search, paid social, programmatic, connected TV, retail media, creator marketing, affiliate, creative video production, analytics, and experimentation. Brands do not need every service, but the selected services should share insights and work toward the same business outcome.

Q3: Do outdoor lifestyle brands need category-specialist agencies?

Category experience is most valuable when it improves audience understanding, creative judgment, seasonality planning, merchandising, and channel strategy. Brands should ask agencies to show how their category knowledge would change the proposed work.

Q4: What is creator content marketing?

Creator content marketing uses material produced by influencers, UGC creators, affiliates, athletes, experts, or other content creators to reach or persuade customers. The content may run organically, through a creator’s audience, in brand-owned channels, or as paid advertising.

Q5: How is affiliate marketing different from influencer marketing?

Affiliate marketing compensates partners based on tracked actions such as clicks, leads, or sales. Influencer marketing commonly pays creators for content production and audience access, although a campaign can also include performance commissions. Some programs combine both models.

Q6: Should a brand hire separate paid media and creative agencies?

Separate agencies can work when responsibilities and communication are clearly defined. A combined partner may be more efficient when creative performance data needs to influence production quickly. Buyers should compare operating models, not assume that either structure is automatically better.

Q7: How much does a performance marketing agency cost?

Pricing depends on media spend, service scope, production volume, technology, geography, and measurement requirements. Common models include monthly retainers, project fees, percentages of media spend, production fees, and performance-based compensation. Request a breakdown of agency fees, media costs, technology fees, creator payments, and production expenses.
