Hey everyone,
I’m a cyclist who’s been using Intervals.icu for a while and I love how clean the planning and load tracking is. My daily headache is still the same though: I own an Oura ring, Garmin watch, follow a training plan and every morning open all my apps and it’s a total mess.
My plan has a solid workout with threshold intervals. Garmin says Low Recovery. Oura says Optimal. My legs feel… meh? I end up staring at the screen for 15-20 minutes trying to decide whether to follow the plan, modify it, measure again my HRV or just bail.
I got tired of it and built the tool I wished existed.
TrueFeel is a simple feel-first daily training decision engine for endurance athletes.
Here’s how it actually works:
- Every morning it asks how you feel (energy, soreness, motivation, stress, etc.) before showing any device or plan data, that one change kills the anchoring bias
- Then it pulls your load and recovery metrics from Intervals.icu, Strava, Oura, WHOOP, and more plus your training plan via iCal feed (works with Intervals.icu and TrainingPeaks calendar export.
- It spots the conflicts [if any] and gives you one clear call: GO, GO WITH LIMITS, MODIFY, or BAIL with a plain-English explanation. And the option to override.
- It learns your personal patterns over time (“meh days for you usually clear up after a 15-min easy warmup”)
- On ambiguous days it has a “Warmup Gate”, tells you to start easy and reassess after 15 minutes instead of guessing.
The decision engine is fully deterministic (rules-based, no LLM hallucinations on the actual GO/BAIL call). Claude only writes the friendly explanations.
It’s in open beta right now use code INTERVALS30BETA at truefeel.ai for a free 30-day trial.
After the trial you can pick whichever plan works for you:
- Monthly — $9.99/month
- Annual (best value) — $79.99/year
- Race Block — $24.99 for 90 days
I’d especially love feedback from heavy Intervals.icu users:
- How well does it use your load and recovery data alongside subjective feel?
- Is combining device metrics with how you actually feel useful day-to-day?
- Does the recommendation style make sense or is it missing something important?
- Any bugs, confusing parts, or features you’d want added?

It’s still very much a one-person side project, so honest feedback (even the brutal kind) is exactly what I need right now. Happy to answer any questions about how it works or the tech behind it.
Thanks in advance!
