Runners who regularly meet on the landmark hill say the amount of rubbish left is increasing on a daily basis and spoiling the area for visitors.
Kim Bennett, a member of Wrekin Road Runners, said: "I go for a run on The Wrekin regularly and it's shocking to see the amount of litter up there.
"There's usually huge pile of rubbish by the main gate, most of which is made up of black bin bags which have ripped open, spilling waste everywhere.
"There are also piles of dog mess around the gate.
"The main route up is littered with plastic bottles and crisp and sweet packets. But the worst thing is the number of plastic bags filled with dog poo, tied up and just left on the main path.

"On Thursday I counted well over 20 in varying states of decay. I can't understand why people scoop up their dog's mess only to leave the bag on the ground where it will stay for a very long time. They should be ashamed."
She added: "We are very lucky to have The Wrekin on our doorstep and presumably the people go there because it is a lovely place to walk – so I can't understand why some of those people consciously spoil the area."
Brian Morris, member of Wrekin Orienteers, said he wasn't aware of signs warning people not to fly-tip or or properly dispose of dog mess.
Peter Holt, whose family owns the Telford side of The Wrekin, which includes the most popular trail to the summit, said that fly-tipping is a real problem.
"It is just a nuisance," he said. "My heart sinks when I come across sofas, fridges and old doors. I put them in my pick-up and take them to the dump, which is what they should've done themselves in the first place."
