Show HN: Workout Tracker – self-hosted, single binary web application (opens in new tab)

I came into the github not expecting to like this, but you've done a great job so far! I currently use a combination of Garmin Connect (track on watch & head unit), Intervals.icu (for fitness/freshness and more obvious tracking of performance improvement over time via various power & HR metrics), Strava (for segment and route performance change over time, and of course the social aspect... and routing), Komoot (only for cycling routing), and Elevate for Strava (just testing now, but it looks like a crappier version of intervals.icu so far), and Smashrun for running-only tracking. Oh, and Veloviewer for cycling-only performance/history and route visualizations.

It's a lot.

The problem is that there isn't a single place where you can get both the holistic metrics and the plan in a way that most users will want (which almost mandates a Strava interface). Apps like Veloviewer or Elevate already have this, but both either fall very short functionally or specifically only target a subset of features.

When I complete a run or ride, the first thing is to check Garmin to see how it related to, or impacted, my physiological health metrics, since I rely on Garmin for things like sleep quality, training readiness, and load tracking. Then to Strava to see how it went compared the previous times on the route and look at segments, or perhaps to give kudos to someone I was with. Then to intervals.icu to dig into the performance metrics (power, HR).

Intervals.icu is great because it handles workout planning, too, but the one big thing it's missing is routes & segments for IRL activities. Veloviewer has this, but it is missing all of the training/planning/fitness features. Imho, the killer app in the space is going to be whoever is able to augment the planning/tracking pieces, which are largely grunt work to develop, with the social bits that Strava has. The existential risk for indy devs is that your product is just a feature for Strava, and you could easily become disintermediated (or they shut down or charge exorbitant rates for API access -- it's already highly rate limited).

You're doing great work, but I'll keep paying for intervals.icu, Strava & Veloviewer for now because they all do slightly different things, even if there's significant overlap.

Sweet! Would love to host this myself and get rid of my Strava subscription.

I wrote a Python script that iterates through all of my activities there and downloads the `.gpx` for each - I could share the code if interested! Not sure how you'd integrate it into your app - maybe a "import from Strava" page could handle the Strava API auth?

I also love this idea of self-hosting some web apps (especially if they're containerized). I setup a `util.` subdomain and have started putting a few things there at different root directories. It's fun!

I love the minor movement toward self-hosted web apps. I wish they were easy enough to setup as installing an app on Android or iPhone.

This is a great looking project. The combo of single binary Go-lang and the ability to package assets like css, js and html makes this a killed multi platform distributable one click run.

It might be an interesting experiment to have the UI be installable as PWA and thereby not need the electron stack to achieve the common functionality offered by these apps.

By "Workout" do mean only exercise that can be tracked via GPS (walking, running, cycling)?

It doesn't seem to track any indoor activities like weight lifting.

This is great! Am a fan of this kind of focused, self hosted application.

Clean UI, too. Interested to hear your thoughts on HTMX when you get around to eval-ing it

This looks truly excellent, nice work! I've been using RideWithGPS, which is a great tool, but doesn't scratch my "self-host everything, own my own data" itch, so I'll definitely be checking this out. I've built (and use daily) my own barebones workout tracker [1], but it's for non-distance-based workouts (i.e. rep-based stuff/lifts), so this compliments that nicely.

This looks super neat and would be very useful. What apps/devices do people use to collec the GPX information? I found a few in the Play Store but they don't look very privacy respecting...

Edit: Currently eyeing GPSLogger: https://gpslogger.app/

Heck yeah, this is awesome.

Any chance of some kind of social features? I want to control my data, but I also do want to be able to share my fitness stats & journey with a specific self-selected group of people: friends, running club mates, etc

Thank you for making this!

Anyone has good resources on importing such data from apple - I’m using Apple Watch but would love to visualize raw data myself with grafana

Well done and congratulations on the launch! Looks incredible mate!

Looks great!

Any chance you plan for it to work with .fit files?

Thanks for making this!

Looks good!! On time for the coming spring!

nice. How do you track teh distance (walked or running?)

Slightly off topic, but I got tired of looking for a good weight training tracker, so instead I bought a notebook and a pencil and I've been using it for nearly two years. If I want to change up how I long my workouts, I just write them in a different way. I've changed how I log number of sets/reps, weight per set, etc, a few times and I've never had to re-program how the info is displayed. I log how I feel after the workout and use that and the weight from last session to guide what I'll be doing in the current session. I don't need a graph as I can clearly see the values going up or stagnating. I honestly feel like the analog process has helped me keep consistent. It's motivated me to get more notebooks to track stuff like household chores. Sometimes the best app is a piece of paper.
