Hi Remi,
V5 is similar but more accurate. The data is processed outside of ChatGPT and returned in a way it cannot add in plausible markers or make up for gaps. If you give ChatGPT raw data, frankly anything can happen! see www.cliveking.net for further explanation or the documentation on github (which i try to keep up to date!)
Thanks for the feedback.
Clive
I really miss that it can see todays workout(s) and wellness data.
Is it possible to add that back? Maybe limit it to the last 2-3 days.
Also need more data with the weekly pulls, avg. HR and avg. Power. as a minimum.
GPT:
The dataset I can currently access through the Unified Reporting Framework (URF) pipeline gives only summary-level metrics (duration, TSS, and distance) for each workout — not the actual HR and power samples from your Intervals.icu activities.
Edit:
I got hallucinations in the data. Made a weekly pull, and it’s making workouts up.
It also adds all workouts from a day together, cant see them apart, time etc.
It can different the timing for different sports on a weekly note, but not daily in the wekly summary.
Hi Hutmacher
For any report you have 42 days of wellness history, you can ask for more info on that after any report. It should always include today’s workout, although ChatGPT may decide not to show it in events data, however it is there. You can always ask it to analyse todays ride or workout etc.
Also remember you will get a better response with ChatGPT v5.2 than v4. I also note that even if you are a subscriber to ChatGPT there is a limit on v5.2 requests before it defaults back to v4 for a period of time. you can verify by asking “what version are you”.
For example:
Weekly Report Generated (URF v5.1)
Period: Last 7 days (ending Dec 22, 2025)
Framework: Unified Reporting Framework v5.1 (Tier-2 Finalized)

Last Ride Analysis — Zwift: zAlpe ×2 (Dec 20, 2025)
Source: Intervals.icu canonical dataset (URF v5.1 Tier-2)
Session Overview| Metric | Value | Interpretation |
|---|---|---|
| Type | Virtual Ride (Climbing / Endurance) | Structured indoor base + tempo block |
| Duration | 2h 27m | Extended endurance block |
| Distance | 55.6 km | Two ascents of Alpe du Zwift |
| TSS | 138 | Solid endurance session |
| Intensity Factor (est.) | 0.76 | Sub-threshold, aerobic focus |
| Normalized Power (NP) | ~240 W | Steady pacing, high aerobic control |
| Average Power | ~210 W | Sustainable tempo output |
| Estimated kJ | ~1 850 kJ | Strong caloric expenditure |
| Elevation Gain (approx.) | 2 ,400 m | Substantial climbing volume |
Intensity Distribution| Zone | Time % | Comment |
|---|---|---|
| Z1 | 12 % | Warm-up / recovery segments |
| Z2 | 35 % | Core aerobic work — well controlled |
| Z3 | 42 % | Tempo / low-threshold climbing |
| Z4–Z5 | 9 % | Short surges near FTP |
| Z6+ | <1 % | Minimal anaerobic effort |
Polarisation = 0.78 → “mixed/optimal” distribution
Balanced between aerobic base and controlled tempo loading.
Physiological Impact| Metric | Value | Status |
|---|---|---|
| CTL Change | +1.3 | Productive gain |
| ATL Change | +3.4 | Temporary fatigue increase |
| TSB Post-Ride | +17 → +13 | Still fresh |
| FatOx Efficiency | 0.69 | Excellent metabolic efficiency |
| MES (Metabolic Efficiency Score) | 22.5 | Aerobically economical |
| Fatigue Resistance | 0.95 | High durability for sustained output |
Interpretation:
This ride consolidated endurance conditioning while mildly stressing threshold metabolism — a perfect late-base session.
Metabolic & HR Insights
Coaching Summary Excellent aerobic base reinforcement — strong climbing economy
No excessive glycolytic bias — balanced metabolic profile
Slight threshold heaviness (42 % Z3) — include a pure Z2 ride next block
Fatigue Trend = –13.7 % — recovery phase maintained
Next-Session RecommendationRecovery Day (Z1 active / walk): maintain form, support glycogen restoration.
Then:
Would you like me to render a power vs heart-rate efficiency chart for this ride to visualize your aerobic drift and pacing stability?
I hope this helps!

I feel the workflow is broken compared to V3 atm.
Edit: - If you didn’t see my edits from the former post
I got hallucinations in the data. Made a weekly pull, and it’s making workouts up.
It also adds all workouts from a day together, can’t see them apart, time, etc.
It can differ the timing for different sports on a weekly note, but not daily in the weekly summary.
I am on 5.2
How, it says it can’t do that, doesn’t have the data?
GPT: - just after I pull a weekly, monthly or 42 days report, it says something like this:
I can’t see your live Intervals.icu activity feed by default — that data sits behind your private athlete profile and must be fetched through a Cloudflare action.
Right now, no “today” dataset is loaded in memory, so I can’t directly display what’s on your account (bike, SkiErg, walk, etc.).
You’ve got two easy options, depending on what you want to view:
| Option | What It Does | Command |
|---|---|---|
| 1. Weekly fetch | Pulls the last 7 days of actual recorded workouts (including today) with durations, modality, TSS, etc. | run a full weekly report |
| 2. Planned lookup | Shows what’s scheduled for today and the coming days (from your Intervals.icu calendar). | look up my planned workouts for this week |
If you want to see what you actually did today, just say:
run a full weekly report (with today’s data)
and I’ll pull the verified record from your Intervals.icu profile.
Would you like me to fetch that now?
If I do that: run a full weekly report (with today’s data)
It hallucinates and missing workouts, skierg, walks
Maybe thats why it hallucinates, because it nows I did walks and Skierg, but cant see that data
Edit: No matter what, it feels stupid compared to V3, this needs exact naming to pull the right data. It can’t figure out what I need from normal conversation.
GPT:
Me: Why is there no SkiErg or walks in this report? Why is there no avg. HR or avg. Power
GPT: We can also fix that: I can run the detailed 7-day full activity fetch, which returns your actual per-session metrics (bike + SkiErg + walk), including average HR, power, and NP.
Me: run a 7-day full report (with detailed activities)
data is not correct and there is hallucinations.
Sometimes ChatGPT privacy rules insist you must authorise the connection even though you have one already via sign in - this is frustrating but not much i can do about it. State:
“i authorise my connection”
it will respond like this
Excellent — your authorization is acknowledged.
Your Intervals.icu connection is now active and verified through the secure Cloudflare → Railway pathway.
That means I can now:
To confirm we’re fully synced — would you like me to:
Fetch and analyze your most recent ride (live from Intervals), or Generate a fresh weekly URF report with updated wellness and load data?If your data is still missing i can check the backend logs to see any issues.
Clive
Me: i authorise my connection
GPT:
blabla do some of this
run a full weekly reportrun a 7-day full report (with detailed activities)run a 42-day wellness reportMe: run a 7-day full report (with detailed activities)
Data not correct, missing workouts, hallucinates etc.
Regards the rollup of workouts in a day, ChatGPT sometimes rolls this up - yes - its not my specification I just pass it the final data, if you ask:
list all events
then you will get something like this
| Date | Activity | Duration | Distance (km) | Load (TSS) | Notes |
|---|---|---|---|---|---|
| Dec 22 2025 | Dog walk | 0h 58m | 5.5 km | 10 | Active recovery / aerobic mobility |
| Dec 20 2025 | Zwift – zAlpe ×2 | 2h 27m | 55.6 km | 138 | Major endurance + tempo climbing session |
| Dec 19 2025 | Dog walk . | 0h 52m | 5.2 km | 8 | Recovery walk |
| Dec 18 2025 | Zwift – Group Workout: BaseCamp Lower-Cadence Tempo with High-Cadence Surges | 1h 31m | 50.2 km | 99 | Sub-threshold & neuromuscular cadence work |
| Dec 16 2025 | Zwift – Group Workout: BaseCamp Aerobic Endurance with 30-30 Tempo | 1h 11m | 37.1 km | 63 | Aerobic + tempo intervals |
| — | Dog walk | 0h 49m | 6.0 km | 12 | Low-intensity recovery |
| — | Dog walk | 0h 50m | 5.1 km | 13 | Active recovery |
| — | Dog walk | 0h 44m | 4.3 km | 11 | Weather-limited short walk |
Yes I get something like that, but the data is not correct, don’t match with intervals.icu.
Missing workouts, and makes workouts up.
Me: Run Detailed 7-Day Report
result: data not correct missing data, hallucinates.
OK understood - please send me screenshots in a PM I will investigate for you.
Thanks I like the report format and your project. However I’m not cycling I’m only running (road+trails) and also doing strength/mobility exercices. Would your agent support my profile? What I’d be after, is a 7day report on the Monday, with also analysis on how the last 7 days went versus the trend on 42days. What I’ve not done yet, is to create all upcoming workouts and cycles in Intervals, so that AI can give recommendation on what to adjust for next +7 days. Typically right now I have some open chats on GPT to feed back progress on my plan and then I adjust manually my calendar workouts in Stryd that will push updated session on my watch to do.
I have started to explore Gemini, however as my chat history is in GPT and I’m on week 9 of a 21 week training plan, it’s hard to switch and migrate to another AI.
It should support running only but i dont have ONLY runs in my profile, so feel free to test! It should use your HR zones. A 7 day report is always a rolling report from whenever its asked right now. Depending on the metric, different data is used, 7, 28, 42 or 90 days is used.
for example:
@Clive_King So here’s another problem that I ran into.
I asked it to analyse today’s 30 minute recovery ride. It responded:
Talked to intervalsicugptcoach.clive-a5a.workers.dev
Today’s Workout Analysis — Recovery RideDate: 23 Dec 2025 | Duration: 30 min (1,802 s) | Distance: 10.9 km | Training Load: 16 TSS
Session Summary| Metric | Value | Interpretation |
|---|---|---|
| Effort Type | Recovery / Low Intensity | Very light spin; active recovery purpose met |
| Intensity Distribution | Z1–Z2: 90.4 % Z3+: 9.6 % | Excellent recovery structure |
| FatOx Efficiency | 0.63 (optimal) | Efficient aerobic metabolism maintained |
| Polarisation Index | 0.90 | Strong endurance focus |
| Recovery Index | 0.72 (moderate) | Slight fatigue present, recovery ongoing |
| ACWR | 0.94 | Productive training balance |
| Fatigue Trend | −13.4 % | Recovering phase confirmed |
Note the intensity distribution – 9.6% in Z3. But intervals.icu has this correct:
Z1 Endurance i1 0% - 67% … 30m3s 100.0%
Something’s gone wrong somewhere…
Hi, good job, I’ve been using the V3 for a while I I find the V5 more solid.
I still struggle to plan workout in the calendar, I continue to get errors. Sny suggestion?
Can’t make it work, error:
no valid activities after moving_time normalization.
tried reconnect, logout, login. Any tips?
Thanks, Calendar is coming. In progress, and am testing this at the moment.

Congratulations! It looks like you have a really nice project. Thank you for the extensive documentation on GitHub as well.
I currently do not have any Garmin devices, so I rely heavily on my Whoop data, which is being fetched by intervals.icu. Unfortunately, it seems that your app is unable to access this data:
- HRV:
Analysis:
Without HRV or sleep data, readiness relies primarily on subjective and training-derived signals. Resting HR and TSB values indicate good parasympathetic recovery.
Recovery Balance
|Sleep quality|⚪ Not tracked|No data source (Garmin Health disabled)|
Is this something you might consider integrating in the future?
Thanks
Olivier
Another remark: I think the intervals API is struggling to find the latest run I made. When I ask “how my run was today”, it refers to the one before and if i insist, the one I have to make tomorrow.
I really hope these comments are useful!
Will add to my todo list. It should not care where it comes from so will look at data again. You can raise an enhancement request here: New Issue select LABEL enhancement.

Yes, i see that sometimes in ChatGPT itself, it’s not intervals. Sometimes I ask to show me my last ride and it shows day before or another day also. In my case I had the last ride/run as a workout, not just a ride! It’s how it processes the data i give it, love AI somedays!
