(of work) so difficult to accomplish that it will literally break the back of the doer.

The child finds his homework to be sorta breakback work.

Breakback Mountain

Tennis - when someone is multiple sets/breaks down, leaving a mountain to climb in order to win.

Djokovic left himself a breakback mountain to climb against Medvedev in the US Open final.
