# Coachbox

> All-in-one training platform that brings coaches and athletes together with everything they need to start, grow, and professionalize in endurance sports.

Coachbox is a coach-centric platform built for endurance sports. At its core stands the coach: Coachbox strengthens their expertise with intuitive, endurance-specific tools, science-backed insights, and an environment that grows with their practice.

The platform is built around four pillars: Software (planning, data, communication, testing, admin, and teamwork), Academy (courses, insights, and practical tools), Matchmaking (helping athletes find the right coach), and Marketplace (training plans and resources).

Used by 25,000+ users across 35+ countries, with 12M+ workouts tracked. Trusted by coaches like Frederik Van Lierde (IRONMAN World Champion) and Tim De Vilder (Founder, PeakLevel).

Coachbox supports running, cycling, swimming, triathlon, rowing, HYROX, and personal training. It integrates with Garmin, Polar, Wahoo, Suunto, COROS, Fitbit, Strava, Zwift, and Apple Health.

The website is available in five languages: English (/en/), Dutch (/nl/), French (/fr/), Spanish (/es/), and German (/de/). The URLs below point to the English pages; each page has a localized equivalent under the other language prefixes, with translated slugs where applicable.

Covers training load, Zone 2, lactate thresholds, POL/PYR periodisation, interference effect, strength periodisation, and fuelling. Floating Coachbox orb available on every page. Persistent per-user memory for coaching style, sport focus, units, and language. Coach-scoped, private, and auditable.

## Integrations

Coachbox connects to the devices and platforms athletes already use. Activities and health data flow in, planned workouts flow out. Which direction a device supports depends on what the manufacturer's API opens up, and every page below states the limits as well as the capabilities.

- [Integrations Overview](https://coachbox.app/en/integrations): All device connections, history imports, and the sensors Coachbox reads. Also explains what the Coachbox AI agents do with the synced data: the chat sparring partner reads activities, sleep and HRV and stages calendar changes that go out to the watch, the workout builder turns a typed session into a structured workout for Garmin, Coros or Wahoo, the workout feedback agent drafts three coach reactions on a finished activity, and the lactate test reader turns a photo of a handwritten protocol sheet into a test. External assistants (ChatGPT, Claude, Gemini) reach the same data read-only over MCP
- [Garmin](https://coachbox.app/en/integrations/garmin): Two-way. Activities, sleep, HRV, resting heart rate, steps and weight come in; structured workouts go out to Garmin Connect and onto the watch. History import goes back about five years for workouts and two for health data, and requires the Historical Data consent toggle
- [Polar](https://coachbox.app/en/integrations/polar): One-way in. Completed workouts and daily metrics import automatically. Planned workouts cannot be sent to a Polar watch because Polar's AccessLink API offers no endpoint for it
- [Coros](https://coachbox.app/en/integrations/coros): Two-way. Activities come in, structured workouts go out to the Coros app and onto the watch. Coros does not deliver daily metrics
- [Suunto](https://coachbox.app/en/integrations/suunto): One-way in. Completed activities and daily metrics sync automatically. Planned workouts cannot be pushed to a Suunto watch
- [Wahoo](https://coachbox.app/en/integrations/wahoo): Two-way. Structured workouts go to the ELEMNT through the Wahoo Cloud API with no manual file step, limited to cycling and running. No daily metrics
- [Fitbit](https://coachbox.app/en/integrations/fitbit): One-way in. Workouts, steps, sleep, resting heart rate and calories. Often used as the daily metrics source alongside a separate training watch
- [Apple Watch](https://coachbox.app/en/integrations/apple-watch): One-way in through the Coachbox iOS app and Apple Health. iPhone only, and each workout is synced with a deliberate tap rather than automatically
- [Tacx](https://coachbox.app/en/integrations/tacx): Two-way, through the Garmin connection. Structured power workouts appear in the Tacx Training app in ERG mode and finished rides return via Garmin Connect. Cycling only
- [Zwift](https://coachbox.app/en/integrations/zwift): Manual today. You export the session from Coachbox and place the file in Zwift's workouts folder yourself, where it appears under Workouts, Custom, coachbox. Power-based cycling and running only, and the file has to be moved from a computer
- [Strava Import](https://coachbox.app/en/integrations/strava): One-time history import. Upload the Strava bulk export ZIP and the full activity history lands in the calendar, with duplicates skipped
- [TrainingPeaks Import](https://coachbox.app/en/integrations/trainingpeaks): One-time history import. Upload the Workout Files export, in twelve-month archives, to move a full training history off TrainingPeaks
- [Stryd](https://coachbox.app/en/integrations/stryd): Sensor, no connection needed. Running power is read straight from the activity file. Runners with a power source get Pa:Hr as the efficiency factor
- [Tymewear](https://coachbox.app/en/integrations/tymewear): Sensor, no connection needed. Breathing rate, minute ventilation and tidal volume are read from the activity file
- [CORE](https://coachbox.app/en/integrations/core): Sensor, no connection needed. Core body temperature and skin temperature are read from the activity file, for heat training and acclimatisation
- [Power Meters](https://coachbox.app/en/integrations/power-meters): Sensor fields. Left/right balance and pedal smoothness are read alongside power and cadence, from any meter that writes the standard FIT fields
- [Running Dynamics](https://coachbox.app/en/integrations/running-dynamics): Sensor fields. Vertical oscillation, vertical ratio, ground contact time and stride length from a watch, chest strap or pod
- [Kayak and Canoe](https://coachbox.app/en/integrations/paddle-sports): Sensor fields. Stroke rate and distance per stroke from Connect IQ paddling apps, so a paddle session gets the same chart, lap, peak and zone analysis as any other sport

- [Case Study: SportSolid](https://coachbox.app/en/case-studies/sportsolid): How SportSolid manages their athletes on one platform
- [Case Study: Lis(t)a Coaching](https://coachbox.app/en/case-studies/lista-coaching): How Lisa runs a fully online running coaching practice from Barcelona. Moved off Excel at around 20 athletes, peaked at 60, now coaches about 40 across Belgium, the Netherlands, Germany, Austria, the UK and beyond. Reviews all training plans in one morning on Monday, Wednesday and Friday, which frees Tuesday and Thursday for marketing, sales and finance. Leans on the AI workout builder, HRV over resting heart rate for recovery, and athlete notes on the menstrual cycle to plan rest weeks. Trail and road running, coaching in English, Dutch and Spanish
- [Case Study: FunctionalCoach](https://coachbox.app/en/case-studies/functionalcoach): Bruno Roels, in sport since 1978 and on Coachbox since 2015, one of the longest-running users. Runs a small endurance practice around his own FATS model (Functional Adaptive Training System) built on homeostasis, supercompensation and adaptation. Uses the workout library and exportable segments to cut admin, and treats AI as a colleague he challenges rather than a threat. Also offers bike fitting, foot fitting, sports nutrition advice and swim technique coaching
- [Case Study: Soigné](https://coachbox.app/en/case-studies/soigne): Dries Béatse grew Soigné in Ronse from one personal trainer visiting clients at home to a multidisciplinary team of eleven, with four physiotherapists and six trainers under one roof. Endurance coaching runs under its own brand, Cadans by Soigné, for runners, cyclists and triathletes. Chose Coachbox because it was usable and did not overwhelm clients with data, since they coach ordinary people combining work and family rather than elite athletes. One month after the Coachbox AI assistant launched they estimated it gave back 50% of their analysis time, used for training readiness checks on HRV and morning heart rate, second opinions on their own programming, zone-2 audits across eight to twelve week blocks, and the AI workout builder for exportable Garmin segments. Dries names the assistant's memory as its most important strength, and reports no hallucinations
- [Case Study: Frederik Van Lierde](https://coachbox.app/en/case-studies/frederik-van-lierde): Ironman world champion 2013, coaching since 2010 and on Coachbox since early 2015. Deliberately caps his roster at 25 age-group triathletes because quality drops with volume. Moved off Excel forms and PDFs, relies on the workout library, and keeps all athlete communication inside the platform rather than WhatsApp so nobody waits days for a reply
