There are 18 racing challenges all across Mars.
The Warp Speed achievement requires the player not olny to finish the races in time, but also to beat the Pro Times in all 18 races.
The challenges will be available as you progress in the game, and can be repeated as many times you want, even after completing the final mission.
There is a playlist on Youtube with all the paths:

Time is tight, but finding the right path and which corners to cut will give some leeway for mistakes (the videos will show plenty of mistakes and still will beat the Pro Times)
For specific races, here are the video links divided by area.
