Pat Rayment has called on the Evo-Stik League to provide a chance for Spalding United to close the gap at the top of the First Division South table.
But Spalding do not have a midweek league game until the trip to Brigg Town on Tuesday, February 24.
Rayment said: “The league are giving fixtures to Sutton Coldfield and Newcastle but ourselves, Mickleover Sports and Leek Town never get a chance to catch them up.
“I find that insane. We’ve had several weeks when we could have played on a Tuesday night.
“We stayed in fourth place for a while because we couldn’t move until we played those games in hand.”
Spalding are at home to Rainworth Miners Welfare on Saturday, looking to make it 15 league games unbeaten.
Rayment added: “We are on a fantastic run but we know what can happen with results in this league.
“Being at home should be an advantage and I don’t think any teams will relish coming here.”
Tulips boss Rayment is expecting to select from a full-strength squad. He has again vowed to “freshen things up” with the starting line-up and formation.
Rayment revealed Jordan Nuttell will come back into the side after regaining his fitness.
Meanwhile, the Tulips have been drawn away to Premier Division title contenders Ilkeston in the Doodson Sport League Cup quarter-final to be played on Tuesday, February 17.
The Lincolnshire Senior Trophy tie at Stamford was called off on Tuesday due to a frozen pitch.
