The Challengers Drive Trail's Culture. The Incumbents Cash the Checks.

Editor's note. Read the numbers here as informed estimates, not audited fact. Trail running is a small and largely private industry that few brands report cleanly, so we've built this from the anchor points we trust — public filings, company-stated figures — and from tools that help without being precise, like SimilarWeb traffic and follower counts, then applied our own read of the sport to fill the gaps. Some of it will be wrong, and that's part of the intent: this is meant as much to start a conversation about the trail industry and the brands that make it up as to be a reference you lean on. If you can sharpen a figure — or a judgment call — we want to hear it. The next version will be better for it.

Trail running is having a decade: US participation up 12.3% in a single year to 14.8 million, North American ultra finishes up roughly 43% in three years, run-club membership up 59% globally in 2024. The sport is surging.

It has also produced a field of brands that's badly misread. The most-followed name in trail is On — which has almost no trail credibility. Several celebrated independents carry followings that rival companies fifty times their size. The signal most people read, social reach, points the wrong way. Size these brands by the thing that actually pays for product — their trail business — and the order scrambles, the giants shrink, and the gap to the challengers turns out smaller and stranger than the logos suggest.

We estimated trail-specific revenue for fourteen brands, and the resources behind each. Three findings.

One: the biggest in the category aren’t trail brands

The field splits by DNA. On one side, the trail-natives — brands built for the mountains from the start. Two reached real scale: Salomon, the mountain-sport originator, and Hoka, born in the French Alps in 2009, which invented maximalist cushioning, the oversized midsole that answered barefoot minimalism. They built the modern sport and are its only billion-dollar trail businesses, an estimated ~$1.8B and ~$1.6B. They aren't the only natives, though: Altra (founded 2009 around zero-drop, natural-running design and a favorite in ultra) and La Sportiva (handcrafting mountain footwear in the Dolomites since 1928) were built for trail too — just smaller, in the low hundreds of millions — as are the independents further down.

On the other side, road-and-lifestyle companies that added a trail line. On is the clearest case: a ~$3.4B business where trail is an estimated 3–4% — about $120M, a small part of the company. Brooks and Saucony are road-first; Merrell is a hiking empire with a trail-running sub-line; Nike reaches trail through its ACG sub-brand. Strip each brand to its estimated trail revenue and a mid-pack forms in the low-to-mid hundreds of millions — Merrell, Nike ACG, Brooks, Altra — with On, La Sportiva, and Saucony in the $80–150M range, above a cluster of credible independents (Topo and NNormal ~$20M, Norda ~$15M, the apparel pair smaller).

Measured this way, the gulf between the big brands and the independents falls from ~112× (total revenue) to ~47× (trail revenue) — still vast, but the story changes from "untouchable giants" to "two real trail giants, a pack of part-timers, and a cluster of small brands punching above their size."

Two: the moat isn't the trail business — it's the backing

The trail numbers understate the giants, because their power doesn't come from trail. It comes from the company behind the brand: a small trail line on a vast balance sheet can be funded across races, retail, and marketing in ways no independent can match.

Nike is the clearest example. As the holding company it is — Nike, Jordan, Converse — its trail entry, ACG, is mid-field by revenue (~$300M) with a smaller owned following than the independents: its official account (~115K) trails even a fan account (~167K). Yet ACG can be everywhere in the sport at once — presenting sponsor of the TrailCon Awards, race sponsorships, global retail, a full marketing push — funded by a ~$46B parent. Altra rides VF's $9.5B; Salomon and Hoka, Amer's and Deckers' billions. Norda runs on an undisclosed minority check.

So the independents are squeezed from two sides. On one, the road-and-lifestyle giants buying in — Nike and On — with capital but borrowed credibility. On the other, the trail-natives who have both: Salomon and Hoka own the heritage and the scale. The deep-pocketed tourist is the obvious threat. The entrenched native is the harder one.

Three: a big following isn't a trail voice.

This is where the misread begins. Rank the field by Instagram and the top is dominated by brands that aren't really trail: On (~2M) leads, with Brooks (~965K) and Saucony (~900K) close behind. Filter to genuine trail brands and, after Salomon and Hoka, reach falls off a cliff — La Sportiva (~510K), Altra (~415K), NNormal (~280K), a quarter to a third of On's.

But a raw follower count is the crudest read of social there is, and it flatters the giants more than anyone. On's two million is a whole-company, mostly-not-trail audience; only a slice of it laces up for the mountains. What actually moves a brand isn't the size of the following but its quality — how engaged it is, how relevant, and whether you can galvanize it when it counts. Instagram has tilted the board further: distribution now runs as much on discovery as on the follow graph, pushing a post to whoever the algorithm thinks wants it rather than to a brand's followers alone. A trail-native with 200,000 obsessive followers can out-reach a lifestyle giant with millions of passive ones — which is precisely the opening the challengers have.

So the trap cuts both ways. Cultural reach in trail looks like it lives with brands that don't depend on trail, so a challenger that matches them follower-for-follower can mistake attention for position — Satisfy's following nearly matches Merrell's, and Merrell earns ~54× more. But the giants' follower piles don't convert to trail authority, or to trail revenue, either. Reach is an asset; it is not a business, and it is not credibility.

The exception is Topo: quiet on social (~70K) but pulling roughly a million monthly web visits (verified) on a DTC model, with the biggest trail business of the independents. It's converting attention into commerce while the others convert it into followers — the metric that matters.

What to watch

Each independent is running a different play against the backing gulf. Satisfy turned the largest challenger following into a multi-season adidas partnership — a $300 Adizero Adios Pro 4, revealed at Paris Fashion Week — buzz as leverage. Norda is betting on racing, on a tear with 2026 wins at Broken Arrow and Zegama and a Western States podium; watch whether results convert to reach and revenue. NNormal has Kilian Jornet, the sport's most decorated name, as co-founder. And Topo is quietly the most encouraging — a real DTC business compounding without the noise.

None of them needs to beat Hoka or Salomon to matter. But the giants don't need to win on trail revenue either — they need only decide trail is worth their backing, and Nike and On increasingly have. Mind the gap that counts. It isn't on the follower chart, or even the revenue chart. It's on the balance sheet behind the logo.

Method & caveats. Brands are sized by estimated trail revenue (total or brand revenue × an estimated trail share) — illustrative estimates layered on estimates; the ordering is more reliable than any single figure. "The company behind the brand" = parent revenue for owned brands (Nike, VF, Amer, Deckers, Designer Brands, Wolverine), own revenue for independents; Brooks shown at its own ~$1.5B (owned by Berkshire Hathaway). Trail-share %s and trail-focus ratings are TBR estimates. Reported total/brand revenue: On, Hoka, Salomon, Merrell, Saucony (FY2025), La Sportiva (FY2024); estimated: Nike ACG (~$300M), Brooks (~$1.5B), Altra, Topo, NNormal, Norda, Path, Satisfy. Web and Instagram figures for the giants are whole-company and overstate trail (On's and Brooks's followings are almost entirely non-trail); Topo's ~1M monthly visits verified (SimilarWeb, May 2026). Industry data: SFIA, UltraRunning Magazine/iRunFar, UTMB, Strava, Circana, The Running Event. An alpha of TBR's Brand Index — a smoke test for a fuller dataset, not the finished product.
