I built a tool to show how people trained for your goal marathon time
The idea for this came from wanting something like Naviance (let’s you see the GPA and test scores of admitted students for a given college) for marathon running. In general, we’re working on making your running data more useful, and our newest tool, called, "Marathon Cohorts," gives you stats about runners who finished a marathon in a given time. You pick a marathon time / cohort and then look at - Weekly training mileage - Fastest 5k, 10k, half marathon, and 30k during training. You can adjust the cohorts to see how these values change as the marathon time gets slower / faster.…

In the maker’s words, at launch
The idea for this came from wanting something like Naviance (let’s you see the GPA and test scores of admitted students for a given college) for marathon running. In general, we’re working on making your running data more useful, and our newest tool, called, "Marathon Cohorts," gives you stats about runners who finished a marathon in a given time. You pick a marathon time / cohort and then look at - Weekly training mileage - Fastest 5k, 10k, half marathon, and 30k during training. You can adjust the cohorts to see how these values change as the marathon time gets slower / faster. If you are logged in and connected with Strava / Garmin, we compute your stats for you and overlay them. But you can explore anonymously–no login required. There’s also a little shareable image generator we’re experimenting with (to make it easier to share on Strava). It’s free right now, but we’re considering a freemium model — and we’d love thoughts on: - Giving users X free queries (per month) before locking the tool? - What would feel worth paying for? - What other stats do you want to see? - Better name for the tool? Let us know what you think!

- IMI made an app to help plan your Weekly Runs2023 · weeklyruns.web.app · ▲5
Hello there, When I started training for the first marathon in my life, I download a 6 months training plan, printed it, pinned it to my fridge, and started circling each completed training day. Sadly, I would often get injured during my runs, which would lead to days or weeks without running, and a lot of changes to the plan I had printed. All running apps that I tried either forced me to follow their plan from the start (which I didn’t want to do because I was already in the middle of training) or made it extremely slow and difficult to add a custom plan. So I decided to create my own app,…

Strava's awesome for viewing individual training runs, but it doesn't offer a consolidated view for elite runners' training. So I scraped >150k activities from 450+ elites with public accounts for their 2024 training log. GH Repo: https://github.com/danielcwq/elite-endurance-viz/ Would love any feedback + feature requests!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
