The race is started by a "Start" button on the toolbar. A message appears on the screen informing the player that the race has started. The "Start" button turns into a "Stop" button. An elapsed time timer is started.
Waypoints can be used to mark points of interest in the world or in the lore. Notice that the player does not have to reach the waypoints in the order specified by the list. This is called "loose" mode. There is also a "strict" mode.
Better get this waypoint before the air runs out. :-)
