Clean minimal black-and-white design

just wanted to say the site looks awesome! I love the minimal black+white/grayscale and the fonts are just lovely. vis looks great too, I enjoyed poking around nearly all of the…
zparky on HNLove how you laid (layed?) everything out. Super clean site.
lippihom on HNGreat job. The website is well done, too. I had a streak of about 400+ days several years ago which I ended the day after a marathon. Today I take off when I am sick or the day…

Impressive streak and dedication
From 3 comments
I'd like to congratulate you on all those 1 mile days - I opened the link expecting to go "yeah, this person is just extremely lucky that they're one of those people that can…
dirkc on HNI admire your dedication. I also like the spartan look of your site. I'm a trail runner and I've been running over 18 years or so, not every day, but two or three times a week.…
wvh on HNWhat a dope website. I used to run every day for a ~year and every since I'm on a decline. Would really love to get into that habit again.

Hand-rolled SVG visualizations admired

I got hopelessly addicted to running in college, then got a knee cartilage injury and haven't consistently ran in 3 years. Absolutely soul-disfiguring for those who love to do…

Miles-only units; requests for metric toggle
From 2 comments
It'd be perfect if we can have a toggle to switch to metric system, like kilometers, meters, celsius for temperature, etc. I find it very hard to follow the numbers expressed in…
musikele on HNImpressive. A nice addition would be adding a switch for converting to non-American units though

Bug in personal bests (5k vs 10k times)
From 2 comments
Something funky with your personal beats. It says your best 5k was in 35:35 but your best 10k was in 43:26. Not possible for those both to be true . I guess the 5k data is screwy…
jmpavlec on HNDefinitely a bug, will fix tomorrow, thanks for catching!

One-mile runs don't count as real runs
From 2 comments
Very cool, but running 1 mile really can't be considered a run of course. So don't reallt see this as ran-every-day-for-10y. Nice vis tho!
timzaman on HNFirst, congrats on your self discipline. Second: About running just one mile in a single day: Does have any physical benefit? (Yes, I know you run more than one mile on many…

Show resting heart rate trends over time
From 2 comments
I'd be curious to see long-term improvements, like resting heartrate over time, or heartrate @ 10 min mile over time.
zug_zug on HNDo you have longitudinal resting heart rate data? Would love to see how it changed over the years.

Improve low-contrast text readability
From 1 comment
Well done! Very inspiring. And a lovely app too. Excellent visualizations. Though the low-contrast is a bit hard to read/see. Do you also use Apple Watch (or other smartwatch)…

Questions
How the runs get into the dashboard and which devices were used
From 2 comments
I really appreciate the website, it's amazing! How do the runs end up on the dashboard? Is that Apple Watch / Strava data that you automatically or manually export? How many…
serial_dev on HNThis really inspired me. I think I will do one on basketball. Great work on data collection for 10 years. Quantified self tracking into a universal format is still really hard.…

Do you have the source/pipeline available? I love the design and would want to do something similar for my own runs. Congrats on the decade! Did you ever focus on specific…
