A VEGAN “supergran” will walk 120 miles non-stop to raise money for the charity that rescued her dog.

Serena Queeney, 67, from Brighton, said being vegan has helped her with her stamina in preparation for the task, which will take 60 hours.

She has mapped out a one-mile loop in the city which she will lap 120 times for charity K-9 Angels, which rescues dogs across the globe.

“After rescuing my little chihuahua Frankie, I wanted to help dogs any way I can,” Serena said.

“I’m walking in one-mile loops around Grand Junction Road and past Habitat where my good friend Judy, 84, will keep track of laps.

“We may be grans but nothing will stop us helping our four-legged best friends.”

This is not the first grand hike the dog-lover has taken on. Serena previously walked 50 miles on the Norfolk coast with a heavy backpack.

“My daughter Suzie and some of the K-9 Angels will be on course to cheer me on and collect donations,” she said. “I’ll be thinking of my Frankie and less fortunate dogs that desperately need our help.”
