Swedish war photographer Jacob Zocherman spent three weeks road-tripping roughly 2,500 miles across California, Utah, and Colorado while shooting the Western States 100 and Hardrock 100 ultramarathons for Trail Runner. His conclusion: "Everything is extreme in America"—politically, geographically, geologically, meteorologically, culturally. On an individual level people are welcoming everywhere, but on a collective level there is suspicion and disagreement between groups.
DC Rainmaker reviews the Garmin Fenix 9 series in depth. The lineup extends LTE and satellite connectivity to solar models and the 43mm AMOLED model, raises base display brightness to 2,000 nits and Pro to 3,000 nits, and makes titanium cases and sapphire glass standard on Pro models.
The ZOLEO Satellite Communicator is presented as an alternative to the Garmin inReach Mini 2. Both address the same problem in different ways: sending messages and calling for emergency assistance. The original gives no specific prices, specifications, or test data.
Bose has confirmed the Sport Open Earbuds, a clip-on open-ear design priced at $199 with IP54 protection and multipoint Bluetooth. Pre-orders open on 19 September ahead of an October 1 launch, and the design puts Bose head to head with Shokz and Huawei's FreeClip 2.

The questionnaire covers pricing, battery life, AI coaching, and direct comparisons with Whoop and five other competitors. The information comes from user research within the Huawei Health app and is currently planning information at the questionnaire stage.
Garmin tactix 9, tactix 9 Ballistics Edition and Enduro 4 have leaked months before any official announcement. The article examines when the tactix 9 is likely to launch and whether satellite messaging may or may not make it onto a watch used on military bases.
Issue 16 covers Garmin Fenix 8 faults on software 23.31, including podcast volume stuck at the alarm level, missing 25 m pool swim lengths, a dead wrist heart rate sensor, halved battery estimates and broken AirPods audio, plus intensity minutes and recovery time lost on 22.35 and Concept2 rowing distance stopping short.
DC Rainmaker's in-depth review of the Apple Watch Ultra 4 finds its optical heart rate sensor is Apple's best yet, but notes that Apple's white paper only compares timestamps where Apple has data and excludes missing points from error calculations, making the 'most accurate heart rate' claim hard to fully support in real-world scenarios.
Ride with GPS's paid Basic plan unlocks 3D maps almost everywhere, with Premium needed only for the web planner. Garmin and Komoot both gate the feature behind their top paid tier instead.
Trail Runner's essay "Imagine If" expresses gratitude for running itself: the author imagines more brittle bones, weaker tendons, and less robust lungs, and asks whether his resilience and patience are merely a product of endorphins and repeated pounding. The piece ends on "But I can. And I will."
Canadian skyrunner Kalie McCrystal went missing on September 1 during a reconnaissance run on the Matterhorn, which straddles the Italy-Switzerland border. Italian mountain rescue authorities called off the search on September 8, and her family said in a September 15 statement that she likely fell while descending.
Garmin accounts for around 78% of the GPS watches tracked by Runalyze, the largest share by far of any brand. That says more about Garmin's grip on serious, data-focused athletes than about the wider watch market.
Huawei Watch D3's Health Glance one-tap check reads up to 11 health indicators in about 60 seconds, covering heart rate, ECG, and a cuff-based blood pressure measurement. The feature is part of Huawei's TruSense health strategy, but the article also notes it doesn't tell you everything.
Runalyze data shows Coros now outranks Suunto and Polar in device share, but the growth is concentrated almost entirely in its cheapest watches. Nearly three-quarters of Coros devices are Pace models, a low-margin base that leaves little room to fund a shift to premium sales.
Trail Runner editors selected the best 2026 trail running hydration vests from 55 packs, tested across Colorado summer trail runs and a 100-mile ultramarathon in the Swiss Alps.

All of the Above Trail Fest (AOTA), a collaboration between The Venture Out Project and Beast Coast Trail Running, held its fourth running on August 29, 2026. There are no podiums; the 20K is a prediction run, the 5K is untimed, and registration collects no gender information, so the winner is whoever guesses their finish time most accurately, not the fastest runner. The event raised funds for TVOP, an LGBTQ+ nonprofit.
Apple announced the Apple Watch Ultra 4 and Apple Watch Series 12, both with the new S11 chipset and a heavily revamped heart rate sensor. Background heart rate readings increase to every 5 seconds and HRV to every 5 minutes. New features include a Readiness Score, a redesigned Health app, and on-device Audio Intelligence arriving later this year.
Chamonix Mayor François-Xavier Laffin says UTMB has become unbearable, with the town effectively turned into one giant outdoor trade show. His office and municipal police tracked brand events, advertising violations and public right-of-way infringements this year, and plan a real framework for 2027 with controls and sanctions after an initial phase of education.
On April 1, 2026, runners gathered for a 50KM event around the Apple campus loop, often called “The Spaceship.” The announcer repeatedly said, “This is not a race.” The event was previously undisclosed. DC Rainmaker has posted a video about it, with more details to follow.

On August 11, the Chinese Athletics Association organized specialized education and training on applying for therapeutic use exemptions. More than 100 team leaders, coaches, and related support personnel participating in the National Track and Field Championships attended. The training was taught by Hu Jia, a national-level clean sport education lecturer, focusing on athletes' safe medication use and therapeutic use exemption applications, strengthening teams' awareness of safe medication use and preventing accidental ingestion or misuse.

On June 30, 2026, Chinese Athletics Association President Sun Yuanfu gave a special Party lecture titled "Deepening the Track and Field Foundation, Solidifying the Foundation for a Strong Nation," proposing the "Four Firm Grasps, Four Always Achieve." He analyzed three sets of contradictions: competitive breakthroughs versus youth training, mass athletics development versus industry standardization, and deepening reform versus high-quality development, noting that road running events have surged but "marathon chaos" still occurs, essentially equating event scale with political achievement. The association will anchor itself to the goal of a sporting powerhouse and do more to build foundations and benefit the long term.
