This is a rather complex bike racing simulation.Each cyclist is determined by no less then 9 characteristics! Movement is determined by the roll of a die, but there are a lot of modifiers - weather (temperature, wind direction and wind speed), the racers characteristics, teammates, road, events,..The material and rules present allow simulation of almost any race.The track consists of different stretches of road you can put together as you like. The game comes with all necessary files in electronic format, so you can make additional track pieces. - BoardGameGeek
