The Step LabWalking, Measured

The Step Lab

Walking, measured: a man who actually walks 20,000 to 50,000 steps a day tests every claim, shoe, route, and walking pad, and publishes the real numbers and the real photos.

No study summaries dressed up as experience. No stock photos. Every number on this site comes from a log: steps, distance, calories, sleep, and gear mileage, recorded daily in Los Angeles by David Christopher Lee.

Start with the calculator below. It is the front door to everything here.

The Step Lab Calculator

Enter your steps and your body. Get distance, time, and two calorie numbers side by side: the standard formula, and the logged model of a man who walks this volume every day. Formulas and limits are on the methodology page.

The full Step Lab, with benchmark tables for every milestone count and the database behind the numbers, lives on The Data page. Its two reference charts are live too: the steps to miles chart and the walking pace chart.

30,000 Steps a Day: What It Actually Does, Measured

Thirty thousand steps is a normal high day in the log behind this site: about 14 miles, a lift-day food target near 4,000 calories, protein at 170 grams, and a very honest account of what feet and joints think about it. The full study, built from dated log entries, is live now. The biggest day on record here is 47,252 steps.

Step Counts: the core franchise

Every step count gets one definitive page: distance, calories, time, what the research says, and what the log says. Updated, never duplicated.

High volume

30,000 to 50,000 steps

Territory almost nobody publishes measured data for. This site does, because this is normal life here.

Walking Pads, Tested at 20,000 Steps a Day

Most walking pad reviews cover a week of desk novelty. Ours run at real daily volume: belt wear, noise, heat, and motor behavior after long sessions, photographed and logged by the mile. The first pad and the current shoe rotation entered the mileage log at launch, and the ranked results publish once the miles are real. Nothing gets an affiliate link here before it gets walked in.

Los Angeles on Foot: 5 Routes I Walk Every Week

Five real routes, each with exact step counts, distance, elevation, time, parking, and photographs shot on a Leica M11 by a photographer with 27 years behind the camera. The route library launches with this piece and grows route by route.
