# Run-It - Data-Driven Running Shoe Analysis

> Run-It is a web application that analyzes your running biomechanics from Garmin or Stryd data to recommend running shoes for your unique running style.

## What is Run-It?

Run-It is a data-driven running shoe recommendation tool. Upload your .FIT file from your running watch, and our algorithm analyzes your biomechanics (cadence, ground contact time, vertical oscillation, stride length) to match you with running shoes that complement your running form.

## How It Works

1. **Upload** your running data (.FIT file from Garmin or Stryd)
2. **Analysis** of your running dynamics (cadence, ground contact time, vertical oscillation, stride length, pace)
3. **Recommendations** for running shoes categorized as Great Match, Good Match, or Not Ideal

## Key Features

- Personalized shoe recommendations based on YOUR biomechanics
- Support for Garmin watches (Forerunner, Fenix, Enduro series) and Stryd power meter
- Analysis of cadence, ground contact time, vertical oscillation, stride length
- Three shoe categories: Daily trainers, Tempo shoes, Race day shoes
- Database of 100+ shoes from Nike, ASICS, Hoka, Brooks, New Balance, Saucony, Adidas, On Running
- Instant results in seconds
- No questionnaires - recommendations based on actual running data

## Supported Devices

- **Garmin**: Forerunner 165, 255, 265, 955, 965, Fenix 7, Fenix 8, Enduro 2, Enduro 3, Venue
- **Stryd**: All Stryd power meters (provides enhanced accuracy)

## What Data Does Run-It Analyze?

- **Cadence**: Steps per minute (SPM)
- **Ground Contact Time (GCT)**: How long your foot stays on the ground per step (milliseconds)
- **Vertical Oscillation**: How much you bounce up and down while running (centimeters)
- **Stride Length**: Distance covered per step (meters)
- **Pace**: Your running speed (minutes per kilometer)

## Shoe Categories Explained

### Daily Trainers
Cushioned, durable shoes for everyday running, easy runs, and recovery runs. Built for high mileage and comfort.

### Tempo Shoes
Lighter and more responsive for faster workouts, threshold runs, and speed sessions. Balance of cushioning and speed.

### Race Day Shoes
Lightest and fastest shoes, often with carbon fiber plates. Designed for competitions, races, and personal bests.

## Pricing

- Free analyses for all run types (daily, tempo, race), custom shoe analysis €0.99 per shoe
- Includes personalized shoe recommendations
- Multiple shoe options per category
- Choose between daily, tempo, or race day shoes
- Choose custom shoes for €4.99

## Frequently Asked Questions

### How do I export a FIT file from Garmin?
Open Garmin Connect, go to Activities, select your run, click the gear icon, and choose 'Export Original'. This downloads the .FIT file.

### Do I need a Stryd to use Run-It?
No. Run-It works with any Garmin watch that records Garmin Running Dynamics. Stryd provides enhanced accuracy but is not required.

### How accurate are the recommendations?
Run-It uses biomechanical analysis based on running dynamics data. Best results come from runs at steady pace on flat terrain.

### Can beginners use Run-It?
Yes! Beginners often benefit most from proper shoe selection. Most modern Garmin watches records the needed data.

### Is my data private?
Yes. FIT files are processed securely and only required information is stored.
