This left Cheltenham bottom of the table, but Allen is convinced they can escape the drop, even if they are 12 points from safety.
He said: "We can still get out of trouble. You could see that from the way we played. The players have shown a fantastic attitude. If we keep playing like that, surely to God it has to change."
But Allen confessed: "This is the most challenging and frustrating period of my career. We've had a lot of injuries and picked up some more in this one.
"However, the players' hard work and attitude keep me going. It is not a challenge to walk away from because they are giving everything they have got."
