How this service works
Gradient percent and angle from rise and distance, plus climbing rate (VAM) and the time to climb at a given rate.
Output
Returns grade percent, angle in degrees, feet climbed, horizontal run in metres, road distance in metres, VAM in metres per hour, average speed in km/h, and minutes to climb — along with metadata fields like summary, verdict, category, and disclaimer.
Example use cases
Pre-ride climb difficulty check
“I'm planning to ride Alpe d'Huez — it rises about 1120 metres over 14 kilometres of road. What's the gradient percent and angle, and how long would it take me to climb it if I can hold a VAM of 1000?”
Segment steepness from GPS data
“My GPS recorded a segment with 80 metres of rise over 600 metres of road distance. Can you tell me the grade percent and angle in degrees so I know how steep that section was?”
Training VAM back-calculation
“I climbed 500 metres of elevation over 8000 metres of road and it took me 45 minutes. What VAM did I average, and what was the gradient percent and angle of the climb?”

Endpoint
GEThttps://bike-calc.x402tookit.com/climb-gradient?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compute cycling climb metrics — gradient, angle, VAM, or climb time — from raw rise and distance figures. It is purpose-built for cycling fitness and route analysis, combining geometric gradient calculation with sport-specific metrics like VAM in a single call.
Side effects
- Missing required riseMeters or distanceMeters parameters returns an error
- Non-numeric values for numeric parameters cause validation failure
- Extremely large or zero/negative distance values may produce undefined or error responses
- VAM of zero would cause division-by-zero for time calculation
