Show HN: I built a tool to show how people trained for your goal marathon time (opens in new tab)

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!
