# Bike software

## Features

- [ ] Detect similar climbs + PRs
- Compute a ride difficulty score (Cotacol method): split into 100m segments, each scores 0.1km × slope²
- On this climb (examples/activity_18679866717.gpx), the climb algo should detect several possible climbs and let you choose
- Once you have chosen, new activities should have remembered the choice (looking into the index should be enough)
- Handling my historical data
- Blog with pictures and markdown
- Storing GPX
- Export mountain pass from OSM and auto detect when pass is crossed
  - https://www.jmspae.se/write-ups/kebabs-train-stations/
- Download French mountain passes from centcols.org into a SQLite database (`go run . -download`, resume with `-resume`)
- Auto detect climbs from GPX
- Compute estimated power
- Export data from Strava, Garmin
  - Garmin GPX exports has elevation, time, temp, heart rate, cadence
  - Garmin TCX export has stats (cal, heart rate, time, cadence), time, pos, alt, distance, hr, cadence, speed
  - Garmin Fit export has (time, sport, lap/split, gps, sensor, events)?
  - KML ?
- Strava seems the simpler to use
- in a single chart, plot (speed, slope) for all segments. color with heartbeat

## Implementation

- Golang for showcase
- Keep improving personal lib (+ documentation)
- Get back what is interesting in previous projects
  - Go bike:
    - Only tooling for golang, project is different

## TODO

- CI / Tooling
- Tests
- linter for calls to `make([]..., n)` that then use append
