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