For athletes training 4–10 hours a week

Most endurance apps are built for professionals who train 15+ hours weekly and have a human coach. RadiantHealth is built for the 80% in the middle — age-groupers, ex-collegiate athletes, serious amateurs — who train 4–10 hours, juggle a job, and want structure without a €200/month coach.

Who this is for

• Age-group triathletes training 6–10 hr/week, chasing a PB for a 70.3 / Olympic distance.
• Runners building to a half or full marathon on 4–8 hr/week.
• Gravel / road cyclists hitting one or two events a year plus Zwift / local rides.
• Strength-and-conditioning hybrids combining lifting with 2–4 conditioning sessions.
• Ex-competitive athletes in their 30s/40s who want to stay sharp without blowing out HRV chasing youth.

Three weeks where the coach actually changes something

These are anonymised composites from pilot users, not press copy. Numbers are real.

Week 1 — the "I feel fine but my HRV says no" week

You have Z4 intervals on the calendar for Tuesday. Garmin morning-readiness is 62/100 (moderate) but the coach sees a second-derivative signal: your 7-day rolling HRV has dropped 11% after a poor night (sleep efficiency 79%, wake-after-sleep-onset 54 min). It also sees you flew home on Sunday from a conference.

• Proposed: Swap Tuesday Z4 → 70-min Z2. Keep Thursday Z4 intact.
• Why it matters: In a 4–10 hr/week block you have exactly one hard bike session + one hard run to protect. Burning that on a low-HRV day has a measurable cost (TSB –17 by Saturday vs. –8 if deferred).

Week 2 — the "I can actually go harder" week

Race is 4 weeks out. Your plan says steady Z2 all week. The coach sees your CTL has stagnated for 10 days, HRV is trending up (+6%), resting HR has drifted down 3 bpm, and sleep has been excellent (8h+ each night, efficiency 92%+).

• Proposed: Add a 4×8 min @ threshold session on Thursday. Push your Saturday long ride from 2h to 2h45.
• Why it matters: Most coaching apps are conservative by default. A stagnating CTL 4 weeks out from a goal race is wasted opportunity. The coach only suggests this because it saw the upstream recovery signals first.

Week 3 — the "life happened" week

You have a Monday strength session, Tuesday intervals, Wednesday recovery run. On Sunday night your Google Calendar gets a 7am dentist appointment on Tuesday. The coach sees the conflict and your Oura sleep debt is 90 min for the week.

• Proposed: Move Tuesday intervals to Wednesday, make Wednesday the easy day on Friday. Strength stays Monday. Long ride unchanged.
• Why it matters: Restructuring a whole week in your head while tired takes 20 minutes and you'll probably get it wrong. The coach does it in one notification.

What the coach will never do

• Prescribe a 12-week plan from scratch. It augments the plan you're already running (Training Peaks, FinalSurge, Runna, your head). It doesn't replace it.
• Make medical claims. If you have a persistent metric drop it will tell you the metric is persistently down and suggest talking to a professional. It won't diagnose.
• Auto-schedule anything. Every action is a proposal you confirm. No surprise calendar writes.
• Punish missed sessions. Missed workouts are context, not a failure score. The next brief just routes around them.

How you'll actually use it

1. Install the app and link one wearable (takes ~1 minute per source).
2. Enable Morning Briefings. You'll get a push at the time you wake up with the day's plan.
3. Tap Confirm on what you'll do. Cancel what you won't.
4. At the end of the day, the agent sees which sessions actually got completed (via Garmin/Strava/Apple Watch) and updates the plan for tomorrow.

Pricing in plain English

Free tier: 5 coach turns per day, morning briefing included. If you train 4–10 hr/week, that's plenty — most pilot users averaged 1.8 turns/day after week two. Paid tiers raise the turn cap and unlock priority model access. We don't paywall the core briefing.
