Hiking, Trail Running and the Crowded Outdoors — 2026-09-23
Top developments
Mount Fuji still packed despite new controls; Environment Ministry to review
Japan's Yomiuri Shimbun reported (Sept 20–21) that climbers still flood the summit pre-dawn for the sunrise ("goraiko"), despite the reservation system and caps introduced in 2026, raising fears of chain-reaction falls on narrow trails near the summit; the Environment Ministry will now verify whether the regulations actually eased crowding. The 2026 season closed with new caps and a ¥4,000 fee reshaping visitor management.

Pikes Peak Marathon results from Sept 20
The Pikes Peak Marathon ran Sunday, Sept. 20, with runners descending Manitou Avenue to Barr Trail; Chrissy Lofgren won the women's race, per The Gazette's finishers roundup — a key result for the US mountain-race scene and points-chasing runners.

Amer Sports raises Q3 guidance on outdoor tailwind
Amer Sports (Salomon, Arc'teryx) raised its Q3 2026 revenue growth guidance to 22% and operating-margin outlook above 14%, citing premium apparel and outdoor strength — a sign trail-footwear demand keeps driving the category. Motley Fool (Sept 17) likewise flagged margin expansion and DTC scaling.
Seoul 100K course revealed — trail racing meets park crowding rules
Korean media (week of Sept 16) reported the official course for the 2026 Seoul International Ultra Trail (Seoul 100K): 2,000 runners, including 170 athletes from 36 countries, across 100K/50K/20K, starting at Gwanghwamun Square and linking Inwangsan, Bukhansan, the Han River and Cheonggyecheon. Crucially, the Bukhansan section includes a "coexistence campaign" — walking-only/slow-pace rules where runners yield to hikers, a model for racing in crowded parks.
Local view
- Japan: Mainichi Shimbun (Sept 23) ran a piece by a mountain writer arguing reckless winter Mount Fuji climbs are "only a tiny fraction," pushing back on alarmist winter-rescue narratives as the off-season begins. Trail Runner JP (Sept 23) advised trail runners to pick insurance based on mountain-rescue ("sainan") coverage rather than injury alone, and previewed the Shin-Etsu Gogaku Trail Race 2026 with live streaming and GPS tracking.
- Korea: Newsis/Daum reported national-park character merchandise sold 209 units a day on average, generating 3.1 billion won in revenue — signage of parks becoming consumer destinations.

Context & numbers
- Mount Fuji: ¥4,000 mandatory fee on all four routes for 2026; 4,000 climbers/day cap on the Yoshida Trail; gate closes at 2 p.m.
- Seoul 100K: 2,000 entrants, 170 from 36 countries, three distances
- Korea national-park goods: ~W3.1bn revenue, 209 items/day
On the radar
- Shin-Etsu Gogaku Trail 2026 (Japan): live coverage and GPS tracking now set up — race imminent
- Environment Ministry's post-season review of Fuji summit congestion could bring tighter summit-area rules for 2027
- Fall hiking season gearing up in US national parks; expect pick-your-own reports on foliage timing in coming weeks
