Endurance Signals and Fueling Sense update: 13 November 2026
Daily Fuel, workout analysis, HRV history and TrainingPeaks history import arrive in Endurance Signals, plus chart zoom and a round of fixes.

Key points
- Daily Fuel arrives: estimated daily energy and carbohydrate targets from your own training. More on this soon.
- Completed workouts now have their own analysis page in Endurance Signals, with a plain-language view for athletes.
- HRV history lets you look back over any past window, including how you responded to a race.
- Coaches can import TrainingPeaks history, and clubs get a weekly email tool.
- Charts zoom, and a round of Calendar and display bugs are fixed. No Fueling Sense changes this fortnight.
This is the first of these Friday updates, so it covers the last two weeks. It has been a busy fortnight, and Endurance Signals is still in a closed trial, so some of this is new even to the athletes and coaches using it.
The part I am most pleased with is Daily Fuel. Most athletes I coach know roughly what to eat around a big session. Far fewer know what a whole day should look like, or how that should change between a rest day and a long ride. Daily Fuel works out estimated daily energy and carbohydrate targets from the training you have planned and the training you have done. It took a lot of research to get here, and a lot of testing against real training weeks. I think it is a major step forward for the platform. I will bring more detail on how it works soon. For now it is off by default, and a coach switches it on athlete by athlete.
The rest of the list is below.
New
- Daily Fuel (coaches switch it on per athlete). Estimated daily energy and carbohydrate targets from an athlete's own training, with a Fuel tab and weigh-in logging.
- Workout analysis (athletes and coaches). Every completed session has its own Activity page: traces, laps, time in zones, heart rate response and an estimate of fuel burned. The numbers are computed in code, and an optional AI debrief explains them.
- HRV history (athletes and coaches). Look back over any past window, including how your HRV responded to a race.
- TrainingPeaks history import (coaches). Upload an athlete's TrainingPeaks exports to fill the days intervals.icu does not have.
- Daily notes (athletes). A one-tap note on the Calendar: alcohol last night, illness, slept well. It appears beside an unusual HRV reading.
- Club tools (clubs). A weekly club email built from the plan, which the coach edits before sending, plus admin and coach roles for club logins.
Improved
- Charts. Drag to zoom on PMC and Biometrics charts, with 24 months and All ranges when your data goes back that far.
- Calendar. Clicking an activity opens a fuller pop-out with the key figures.
- Signals card. Shows the top four signals, with "See all" for the rest.
- Strength Coach (athletes who have it switched on). Your programme downloads as a PDF cue card.
- Public pages. A product page, a glossary and a getting started guide.
Fixed
- Paces such as "4:60/km" now show as "5:00/km".
- Pairing an activity with a planned session on the Calendar works again.
- "Clear plan" now clears only today onward, not past days.
- "Remove duplicate" on the Calendar is no longer blocked.
- Empty Strava activities no longer show on the Calendar.
- The AI workout debrief and signals digest are no longer refused when the text is correct.
I will come back to several of these in their own posts over the coming weeks.
