trudge along
to plod along on foot. It seemed as if we trudged along for miles. As we trudged along, we forgot how cold it was.
trudge through something
1. Lit. to walk through snow, sand, or something similar. We trudged through the hot sand all the way down the beach. I used to have to trudge through snow like this all winter to get to school.
2. Fig. to work one's way through something difficult. I hate to have to trudge through these reports on the weekend. I have to trudge through a lot of work before I can go home.
