Training to run a marathon is tough.
But it may be more difficult for all of your friends and family who can’t stop hearing about it.

I took it one step further by ingesting, modeling, and visualizing my heart rate data collected during my training:

1. Extract Load with custom Python code
   Garmin API -> local ndjson file in FHIR format -> Duckdb

2. Transform & Test with dbt
   Duckdb raw -> staging -> analytics

3. Visualize & Analyze with Visivo

At least my choice to build with a completely local, open source data stack made it fun and easy!
