StemNotes: Cycling Fuel

Stop guessing your ride nutrition. StemNotes builds a carb plan from your training and sends it to your Garmin or Karoo, with an alert for every feed.

Know exactly how much to eat, and when.

StemNotes builds a fuelling plan for every ride from your own training. Connect TrainingPeaks or intervals.icu and it reads each planned workout, then works out the carbs you need, block by block, from the session's power and your FTP. No more doing mental maths on the bike. No more bonking on the long ones.

Then it puts the plan where you actually need it: on your bars. Send it to your Garmin Edge or Hammerhead Karoo and get a clear "EAT 40g" prompt at the right moment, with a countdown to your next feed.

HOW IT WORKS

Connect TrainingPeaks or intervals.icu. StemNotes imports your week and builds a carb plan for each ride. See the grams to take at each feed, timed across the workout and matched to how hard each block is. Push today's plan to your Garmin or Karoo and ride. It tells you when to eat.

WHAT YOU GET

Fuel for the work required: harder efforts and longer rides get more, easy days get less. Your limits, respected: set your max carbs per hour and feed interval, and the plan stays within your gut. On-bike prompts: a Garmin data field and a Karoo field with timed "eat now" alerts and a live countdown. Completed-ride review: see what you should have taken compared with your plan. A weekly calendar of every session with its fuel total at a glance.
