A one-horse race
Ahead of the game
Move the goalposts
To be neck and neck
Keep your eye on the ball
A level playing field
On the ropes
In the driving seat
Flogging a dead horse
A major player
A change in the rules
Being at the same level as the competition
Being in a very bad situation
Being in control
Being the only competitor
Being in front of the competition
An important company or person with a lot of power or influence
Wasting your time on a hopeless situation
A situation of fair competition
Staying focused
