Abstract: The invention relates to an application server for use in a mobile communication network, the application server being arranged for: —receiving position information on positions of a first mobile terminal; —calculating a distance traveled since a starting time for the first mobile terminal; —comparing the distance traveled with a distance traveled by a competitor to render a relative distance; —sending feedback information to the first mobile terminal relating to the relative distance. The competitor can be based on a real participant that has done the race before (in theory the end-user itself) or a fictitious opponent that was selected on criteria like average speed. The system can be used during races and may provide information to participants, spectators and officials via bill-boards and/or voice messages and/or SMS messages.
