Loop Runner

Pick a distance and get a fresh running loop that starts and ends at your door.

Nobody has claimed this yet. Be first.

The idea

Runners get bored of the same route and guessing distances is annoying. Loop Runner generates a few loop routes of the chosen length from your location, shows them on a map, and saves favorites. Good for travelers running in a new town too.

Your first AI prompts

Paste these into Claude, Cursor or Lovable, in order. Check that each one works before moving on.

PROMPT 1 OF 3

Build an Expo app called Loop Runner. Start with a home screen showing the current location on a map, a distance picker (in miles or km), and a Generate button.

PROMPT 2 OF 3

Generate 3 loop options by picking waypoints in different directions around the start at a radius based on the distance, then request walking directions through them with the Google Maps directions API. Keep routes within 10 percent of the target and show each with distance and elevation gain.
