The Race portrays a puzzle-based race for 50 million dollars through the most scenic locations of Peru. With one friend at your sight, you must defeat eight other teams striving for the prize by interpreting clues, thinking up the fastest ways to get from A to B, and solving puzzles along the way.
In terms of writing and characterisation, The Race is not very memorable, though the Peruvian setting partly makes up for this. However, as a puzzle-rich piece of CYOA, it is fun and of considerable interest. Anyone who would like to think about how puzzle design in a multiple choice medium works, should take a look at this piece. The Race is also to recommend to all those who simply want to play such a game.
(I do think that the piece would have been improved by scenery photographs to accompany the location descriptions.)
