Physicist Rigged His Pet Hamster's Wheel to Strava. It Runs Far Every Night

Ranked #5 on Hacker News with 55 points and 7 comments.

Meet Mollie, the 10-month-old hamster whoโ€™s been logging serious mileage.

I use Strava for the obvious stuff, like runs , HIIT classes, and the occasional commute that goes full workout when Iโ€™m desperate to get my steps in. Iโ€™m not a pet owner, but I can understand a dog walk making it on there, too. The dog may be involved, but at least youโ€™re still the one doing the walking.

But workouts uploaded from a hamster wheel? That feels like new territory.

Thijs de Buck, an MRI physicist based in Utrecht, the Netherlands, recently posted on Reddit that he built a speed and distance tracker for his hamsterโ€™s wheel, with the data automatically uploaded to Mollieโ€™s own Strava account . Mollie, his 10-month-old hamster, is now committed to logging nightly runs with distance, pace, and time.

One recent activity showed 6.06 miles in 4 hours and 37 minutes. The next night, Mollie logged 5.55 miles in 3 hours and 56 minutes.

At first, de Buck just wanted to know how much distance Mollie was covering after dark.
