PoGo trainer Jytale compiled data trying to find out which was better to hatch eggs. In the information listed below. Jytale found out that no matter what form of transportation, not all distance was calculated. The best means of transportation for hatching eggs and walking your buddy Pokemon would be walking in a straight line.
WALKING AT 1.2 MPH AVERAGE: WALKING ON A MOSTLY STRAIGHT PATH 5KM ACTUAL DISTANCE = 4.4 KM TRACKED WALKING ON A CURVY PATH WITH TURNS 5KM ACTUAL DISTANCE = 4.1 KM TRACKED JOGGING AT 4MPH AVERAGE JOGGING ON A STRAIGHT TRAIL 5KM ACTUAL = 4.2KM TRACKED JOGGING ON A CURVY PATH WITH TURNS 5KM ACTUAL DISTANCE = 4KM TRACKED RUNNING 6MPH AVERAGE SPEED RUNNING ON A STRAIGHT PATH 5KM ACTUAL DISTANCE = 4 TRACKED RUNNING ON A CURVY PATH WITH TURNS 5KM ACTUAL DISTANCE = 3.7 TRACKED BIKING 9.4 MPH AVERAGE SPEED
biking on a straight path 5km actual distance = 3.5km tracked* biking on a curvy path with turns 5km actual distance = 3.3km tracked* Driving (in car as a passenger, don’t play and drive) 15mph average speed Driving on a mostly straight road 5km actual distance = 3.3km tracked Driving on a curvy road with turns 5km actual distance = 2.9km tracked
IN CONCLUSION The faster you go the less it tracks, the curvier the path the less it tracks.
Here is a chart showing the data Pogo trainer collected. Though it doesn’t say his means of getting around. His numbers are close to Jytale’s. With an average speed of 1.2 miles per hour being the best speed to track distance. It looks like if you want to efficiently hatch your eggs, walking is the way to go.
