ARTIE

A training log and race tracker for a prone paddleboard crew out of Redondo Beach, training for the Catalina Classic, a 32-mile open-ocean race from Catalina Island to the Manhattan Beach Pier. The name comes from R10, the buoy off Palos Verdes the crew paddles out to and back from.

What it does

• Logs workouts from whatever you have. Paste a Garmin activity link, add screenshots of the Garmin app's Overview, Stats, Laps and Charts tabs, or enter a paddle or swim by hand. A .gpx, .fit or Garmin CSV export works too.
• Reads Garmin screenshots with Claude. Each screenshot is sent to Claude, which works out which tab it is and copies every value exactly as shown; units are converted in code, not by the model. A link plus screenshots, picked all at once in any order, becomes one workout, and pieces added later fill in what an existing workout was missing.
• Mileage Tracker. A per-season leaderboard of paddle, ocean-swim and pool-swim miles, above a month-by-month log.
• Records. Fastest 1, 2 and 3 back-to-back miles, from mile splits.
• Races. Countdowns to upcoming races with sign-up links, and results for past ones with the crew highlighted, matched by first and last name so a stranger with the same surname isn't.
• Conditions. Live and still-photo surf cams for Topaz, the Manhattan Beach Pier and Hermosa, with water temperature, wave height and morning wind.
• Imports from Strava and from Reggie, a companion swim-registration app.

Only the readings people trust are kept: heart rate only for athletes who wear a chest strap, and stroke counts only for swims.

How it's built

• Next.js 16 (App Router), TypeScript, Tailwind CSS v4
• PostgreSQL on Supabase
• Claude Haiku (Anthropic API) for reading screenshots and share cards
• Railway for hosting, deploying from main
• NOAA buoy data and Open-Meteo for conditions

Sign-in is a name plus a shared team code, kept in a signed cookie so middleware can check it without a database round trip. Guests can browse everything but change nothing.
