Why Brick

Built different on purpose.

Generic endurance apps weren't designed for three sports, real training history, or athletes who want control. Brick was.

Triathlon wasn't an afterthought

Generic endurance apps were built for one sport and adapted for three. Brick schedules brick runs as atomic pairs, handles sport doubles with hard/easy spacing, manages B/C race overlays without blowing up your season, and includes open-water swim racecraft — because triathlon has rules that don't exist anywhere else.

Long ride + brick run scheduled together in build and peak
B-race mini-tapers and C-race train-through rules
Open-water and sighting-drill sessions for race-day confidence

Plans anchored to what you've actually done

Brick doesn't start from a generic hours-per-week slider. Demonstrated capacity uses two horizons — recent 16-week volume and yearly 52-week volume — with comeback credit after layoffs. Your plan ramps from real training history, not assumptions.

Safer volume progression than template-based plans
Comeback credit after time off
Threshold-fraction prescriptions across swim, bike, and run

Weaknesses become training focus

Nightly fitness snapshots detect limiters — aerobic base, bike power, run volume, swim frequency, gray zone, run speed — and reshape your workout pools. When a limiter is severe enough, Brick can even extend your base phase. Your data feeds back into plan structure in a closed loop.

Targeted workouts prepended to your rotation queue
Aerobic decoupling and compliance feed the intelligence layer

AI coaches; engineers plan

The calendar structure, volume ramps, session selection, and adaptations are rule-based and reproducible. AI is reserved for what it does best — morning briefs, session debriefs, weekly reviews, and conversational coaching. Your next workout isn't a language-model guess; it's a deterministic decision you can understand.

40+ parameterized archetypes, not AI-generated randomness
AI narrates rationale; the engine decides structure
Evidence-linked debriefs tied to specific data windows

Trust by design

Brick was built for athletes who want a coach's judgment without giving up control. Every plan change arrives as a proposal you accept or dismiss. Health data lives under explicit consent. You can export everything or delete your account at any time.

Consent-gated proposals — never silent calendar edits
Versioned health-data consent with GDPR export
Transparent AI usage budget

FAQ

Frequently asked questions.

What is Brick?

Brick is a triathlon-native AI coaching platform. It creates individualized swim/bike/run plans from your real training history, adapts them through consent-gated proposals, and explains every decision — from morning briefs to session debriefs.

How is Brick different from other training platforms?

Brick is built for triathlon from the ground up — brick runs, sport doubles, B/C race overlays, and open-water swim. The plan engine is deterministic and anchored to demonstrated capacity, not generic templates. AI coaches through briefs and debriefs, but you approve every adaptation. No silent calendar edits.

Who is Brick for?

Serious amateur triathletes and multisport athletes — whether you're building toward your first sprint or chasing a Kona slot. If you train around work, family, and real life, Brick was built for you.

Does Brick auto-change my plan?

No. Readiness shifts, missed sessions, and fitness changes trigger proposals — step up, step down, reprioritize, or recalibrate. You review and accept or dismiss each one. Your calendar never changes without your approval.

What is demonstrated capacity?

Brick anchors your plan volume to what you've actually trained — using two horizons: recent 16-week volume and yearly 52-week volume. After a layoff, comeback credit prevents unsafe ramping. It's safer than picking hours from a slider.

What metrics does Brick track beyond CTL?

Brick Performance Index (multi-sport capability vs. your baseline), goal likelihood (race-day projection with on track / stretch / at risk bands), race readiness, limiter detection, and daily readiness scores from HRV, sleep, check-ins, and compliance.

What does Brick sync with?

Strava, Polar, Wahoo, WHOOP, COROS, Suunto, Hammerhead (Karoo), Garmin (via intervals.icu), and direct .FIT file upload. Workouts push to Garmin for execution; activities sync back for analysis, compliance scoring, and PR detection. iCal export is also available.

Is my health data safe?

Yes. Health data lives under explicit consent, integrations are encrypted, the AI budget is transparent, and you can export or delete everything at any time. Your data is yours.
