YOUR W′ TRACKER DOESN'T TELL THE WHOLE STORY. Your W′ balance can look full even when your legs are fading. That's because W′ trackers focus on your reserve for hard efforts—not all the fatigue that builds during a long ride. Never Bonk Again goes further. It estimates BOTH your remaining endurance and your ability to push hard again, so you can make better decisions BEFORE you run out of steam. WHY CHOOSE NEVER BONK AGAIN? • MORE THAN JUST W-Prime — ENDURANCE for long, steady efforts and SPRINT for hard efforts. Useful in road races, gravel, time trials, and criteriums. • FATIGUE MATTERS — After two hours of hard riding, you're not as fresh as you were at the start. Our models account for fatigue as it builds. • CONDITIONS COUNT — Temperature, altitude, and your personal settings affect the estimates. • IT LEARNS ABOUT YOU (LICENSED) — Uses your ride history to adjust estimates to your performance, rather than relying only on fixed numbers. • JUST GLANCE AND RIDE — No dashboard to study in the middle of a race. See your capability bars and decide whether to push or ease off. • TIMELY WARNINGS — Alerts when your heart-rate response suggests unusual strain or possible performance deterioration. WHAT YOU SEE DURING A RIDE ENDURANCE INDEX: Estimated endurance used during sustained riding. SPRINT INDEX: Estimated high-intensity capability used, combining W′ with the Lactate accumulation model for hard efforts. CRITERIUM MODE VIEW: A bigger Sprint gauge and Matches Left for races with frequent accelerations. Know how many matches you have left. Estimated remaining short, hard efforts (about 10 seconds at twice your FTP per match). COMPANION MOBILE APP: The companion web app lets you: • Manage rider settings • Review Endurance and Sprint use for each ride • Follow how your estimated capabilities change over time Web app: https://production.d3hh6od5h85xgu.amplifyapp.com/ FREE TO TRY FREE: Endurance, Sprint, and Matches Left with standard model settings. LICENSED: Adaptive learning from your rides and advanced Garmin Connect data recording. License information: https://www.neverbonkagain.com/ WHAT YOU NEED A compatible Garmin bike computer, power meter, and heart-rate monitor. Enter your FTP, maximum and resting heart rate, Today's Recovery, and best 2-minute and 5-minute powers. Don't know the last two? You can estimate them from FTP, although tested values are recommended. For web-based settings, enable “Use mobile settings” in the data field, sync your Garmin, and start an activity containing the field. Confirm the field is active. You can add the web app to your phone's home screen. Enable Garmin Data Field Alerts to receive warnings. Changing FTP or the 2-/5-minute power inputs resets learned factors for the new baseline.

Use them alongside how you feel and your own judgment.

CR3.5 September 2026 Update Introducing the Never Bonk Again companion web app! Manage your settings, review capability usage on individual rides, and follow your learned capability trends. The data field now saves ride data to our server so you can review it in the web app. Open the web app: https://production.d3hh6od5h85xgu.amplifyapp.com/ To use web app settings on your Garmin, enable “Use mobile settings” in Never Bonk Again’s Connect IQ settings. Watch the update: https://youtu.be/Zofnf6pshkY CR 3.0 What’s New This update makes Never Bonk Again easier to configure and provides clearer information before, during, and after your ride. Improved Notifications In-ride notifications have been redesigned to make important changes in your performance capability easier to see while riding. The post-ride summary has also been expanded to show the settings used for the ride, maximum Endurance and Sprint depletion, whether cardiac decoupling or bonking occurred, and whether your learned Endurance and Sprint capabilities remained stable, improved, or decreased. Estimate Your Power Curve from FTP Don't know your maximum 2-minute and 5-minute power? You can now select Estimate Power Curve from FTP, and Never Bonk Again will calculate the values needed to establish your initial power curve. For the best personalization and accuracy, we still recommend performing actual 2-minute and 5-minute maximum-power tests and entering those results whenever possible. The FTP-based estimate is designed to make getting started easier when those values aren't available. Metric or Imperial Units You can now select Metric or Imperial units for your typical riding-environment settings, allowing temperature and altitude to be entered using °C/meters or °F/feet. Improved Settings The settings screen has been reorganized to make rider information, power settings, typical riding conditions, display options, and licensing easier to find and understand. Pre-Ride Check Before starting your ride, the data field now provides a simple confirmation of your license status, FTP, and Recovery setting, making it easy to verify the most important inputs before you press Start. Important — Enable Data Field Alerts The improved in-ride notifications and ride summary use Garmin's Data Field Alerts. Make sure Data Field Alerts are enabled for the activity profile where you use Never Bonk Again. You only need to enable this once for each activity profile.
