NetAthlon permits customizing characters and users have done just that.

Would you like to race with Pantani, Armstrong, Ullrich, and others? 

Well, join the Yahoo NetAthlon users group and you will find the instructions on how to do this.

http://sports.groups.yahoo.com/group/netathlonbicyclists/files/CustomTextureSets-RoadBike/

You will need to join this group (takes minutes) and with a little work your courses and races can include famous riders (FitCentric has no commercial interest in this enterprise, by the way). Parts of our software are open to users to customize THEIR copy.

No other virtual product does this.... none of them.
