Real time performance comparison involves identifying predefined route data corresponding to a route. Measured locations are detected while a user traverses the route carrying a mobile device. The measured locations are sent via a network synchronously with the detection of the respective measured locations. Comparative data points are derived based on the predefined route data and the measured locations in response to receiving the measured locations. The comparative data points are sent, via the network, in response to measured locations. The comparative data points allow the user to measure relative performance during the route traversal.
