Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older.

I built a free, no login tool that calculates and shows the current year as a progress bar with continuously updating percentage, and 3 other visualization models. It has a customization feature where you can track any time period up to 100 years as a progress bar, and a lifespan feature where you input your birthday and sex. It handles leap years, time zones, and runs automated weekly snapshots via GitHub Actions + Puppeteer and posts on X. Would love feedback on the model or edge cases I might have missed.
