What is {primary_keyword}?
The {primary_keyword} is a tool that uses geographic coordinates to compute the straight‑line distance between two points, then applies your average running pace to estimate total time and calories burned. It is especially useful for runners who plan routes using Google Maps but want a quick estimate without manually measuring each segment.
Anyone who runs regularly, plans long‑distance training, or wants to compare different routes can benefit from the {primary_keyword}. It helps you understand the effort required before you even step onto the pavement.
Common misconceptions include believing the {primary_keyword} provides road‑network distance (it does not) and assuming it accounts for elevation changes (it does not). It simply calculates the “as‑the‑crow‑flies” distance using the haversine formula.
{primary_keyword} Formula and Mathematical Explanation
The core of the {primary_keyword} relies on the haversine formula, which determines the great‑circle distance between two points on a sphere given their latitudes and longitudes.
Formula:
Δlat = radians(destLat - startLat) Δlon = radians(destLng - startLng) a = sin²(Δlat/2) + cos(radians(startLat)) * cos(radians(destLat)) * sin²(Δlon/2) c = 2 * atan2(√a, √(1−a)) distance = R * c
Where R is the Earth’s radius (≈6371 km). Once distance is known, estimated time = distance × pace, and calories ≈ distance × weight × 1 kcal/kg/km (using a default weight of 60 kg).
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| startLat | Start latitude | degrees | -90 to 90 |
| startLng | Start longitude | degrees | -180 to 180 |
| destLat | Destination latitude | degrees | -90 to 90 |
| destLng | Destination longitude | degrees | -180 to 180 |
| pace | Average running pace | min/km | 3 to 10 |
| R | Earth radius | km | 6371 |
Practical Examples (Real‑World Use Cases)
Example 1: New York to Los Angeles
Inputs: Start (40.7128, -74.0060), Destination (34.0522, -118.2437), Pace 5 min/km.
Result: Distance ≈ 3936 km, Estimated Time ≈ 19 800 min (≈330 hours), Calories ≈ 236 160 kcal.
Example 2: Central Park to Brooklyn Bridge
Inputs: Start (40.7851, -73.9683), Destination (40.7061, -73.9969), Pace 4.5 min/km.
Result: Distance ≈ 9.5 km, Estimated Time ≈ 42.8 min, Calories ≈ 570 kcal.

Key Factors That Affect {primary_keyword} Results
- Latitude/Longitude Accuracy: Small errors can change distance noticeably.
- Average Pace: Faster paces reduce estimated time proportionally.
- Runner Weight: Heavier runners burn more calories per kilometer.
- Terrain Type: The {primary_keyword} assumes flat ground; hills increase effort.
- Weather Conditions: Wind or temperature can affect actual pace.
- Route Choice: The straight‑line distance may differ from road distance used in practice.
Frequently Asked Questions (FAQ)
- Can the {primary_keyword} calculate road distance?
- No, it uses the haversine formula for straight‑line distance only.
- Do I need a Google Maps API key?
- No, the calculator works offline with manual coordinate entry.
- How accurate is the calorie estimate?
- It assumes 1 kcal per kg per km; actual burn varies with intensity and metabolism.
- What if I don’t know my coordinates?
- You can obtain them by right‑clicking a location in Google Maps and selecting “What’s here?”.
- Can I use the calculator for cycling?
- Yes, but adjust the pace to minutes per kilometer for cycling speed.
- Is elevation considered?
- No, elevation changes are not included in the current {primary_keyword}.
- How often should I recalculate?
- Whenever you change start/end points or your average pace.
- Can I save my results?
- Use the “Copy Results” button and paste into a document.
