Milk Race is a computer game released in 1987 for the ZX Spectrum, Commodore 64, Atari 8-bit, MSX and Amstrad CPC and was developed by Phil Berry, Stuart Ruecroft and David Whittaker for Icon Design Ltd.
Based around the internationally acclaimed event in world cycle race The Milk Race (now known as Tour of Britain). This simulator was designed to coincide with the 1987 event, starting in Newcastle-upon-Tyne, through the North of England, and down through the Midlands, to London for the finishing line. The basic premise of the game is to control a bike using acceleration, braking and choosing the correct gear to conserve energy.
