Elevation gain and loss
Learn why elevation can change on a flat route.
Elevation comes from device location and altitude readings. Buildings, bridges, and GPS multipath can create noise, so small gains and losses are estimates rather than a survey.
What to do
- Review the elevation chart with the route context.
- Expect more noise indoors or between tall buildings.
- Use a barometric device for important comparisons.
