The Cycling Brief

Daily cycling intelligence from SEMIPRO CYCLING, produced with AI-assisted research, scripting, and synthetic voice.

Most riders treat fuelling as bonk insurance. A new study says your bottle is doing something bigger: protecting how hard you can go late in a ride. Carbohydrate preserved critical power at hour three in a clear dose-dependent way, though it did nothing for your sprint. Plus a rethink on VLamax, the gym, and what actually raises your glycolytic power.

This week's study: Norte BR, Slinn MM, Johnson KO, et al. Graded Carbohydrate Ingestion up to 120 g/h Attenuates the Reduction in Critical Power Following 3 h of Moderate-Intensity Exercise in a Dose-Dependent Manner. Scandinavian Journal of Medicine & Science in Sports. 2026;36(6):e70326. doi:10.1111/sms.70326

The Cycling Tech Brief: the cycling tech that actually matters today — and whether to update, wait, or ignore.

• Shimano XTR M9200 Di2 enters real-world circulation — a year of waiting, now in shops and on trails — Monitor — early impressions are compelling and it's now in stock, but let a full season of racing and user data accumulate before committing at this price.
• Campagnolo's 13-speed platform expands: Record 13 launches at ~€2,100, bringing the full Super Record architecture to a wider price tier — Update — if you're on Campagnolo or evaluating a top-tier wireless group, Record 13 is now the most accessible entry to the platform; verify your hub standard and Ekar cassette compatibility before ordering.

Replacement Tech Brief: cycling tech that matters today, with the repeated TrainingPeaks story removed.

• Garmin Vivoactive 6 / Venu 4 Beta 18.12: Voice Wake Word, Dozens of Reset Fixes, and Workout UX Overhaul — Beta participants: install and test — the reset-fix sweep is substantial. On stable? Hold at v17.33 and monitor for the stable graduation of this build.
• EDITORIAL FLAG — Item 151 (v1.33.1 / 'Garmin' / EMTB Forums): Metadata Mislabel, Story Cannot Be Verified — Do not air — re-route to editorial for correct brand attribution and re-sourcing before scheduling.

• TrainingPeaks Launches Athlete Home: A Single-Screen Daily Training Dashboard for Premium Users — If you're a Premium subscriber, check your updated Athlete Home for the new Fitness/Form/Fatigue trend view — it's worth a few minutes to customise the layout to match your training priorities.
• Zwift Events Fail to Load for Some Users — Platform-Side Issue Under Investigation — If your event list won't load, force-quit the app fully and relaunch before your session start time — and keep an eye on the Zwift forums Known Issues board for a fix.
• TrainingPeaks We Speak Peak Series: Jayco AlUla Sport Engineering Director Explains Tour de France Data Strategy — If you're deep in your Tour de France training inspiration mode, the Jayco AlUla Q&A is worth a read for a concrete look at how Climb Detection and load tracking are applied at the WorldTour level — then try applying the same logic to your own upcoming event.

• Zwift PC app fails to launch after update — crashes on startup with error code 0xc0000005 — Hold off on forced reinstalls — they pull the same broken build. Monitor the official Known Issues thread for a confirmed fix before troubleshooting further.
• Bravur x Zwift mechanical watch: 100-piece luxury collab at $1,195 — no GPS, no sensors, no apology — This is a collector's object, not a training tool — monitor availability if you want one, but do not expect a performance benefit.
• TrainingPeaks 'We Speak Peak' adds Astana — TdF-eve content series now covers its fifth WorldTour team — Monitor if you're a coach or serious athlete curious about WorldTour altitude and stage-race methodology — but this is brand content, not a product update.
