A NINE-year-old who has been sharing the message of how the great outdoors can benefit those suffering from Tourette's syndrome has completed his 100th Wainwright. 

Leo Mason from Allonby, alongside his dad, Michael Mason, have set themselves the challenge of completing all 214 Wainwrights before his eleventh birthday. 

Despite struggling with involuntary tics, Leo has found great benefits in physical activity.

Initially suffering from twitching and verbal tics, Leo has seen a significant decrease since starting his climbs and looks to spread the message to others. 

"The weather has been horrendous this year but Leo has completed 40 this year so far. He was so happy to hit 100 up Calf Crag," Michael said. 

"It's getting done a lot quicker than we thought."

Leo, with aspirations to become a professional climber, has also launched his merchandising line under the Ticknemoff brand with some of his products being picked up and sent across the world. 

"We've got our first group hike on Sunday up Rannerdale Knott," Michael said. 

"We've had families reach out who also have kids with Tourette's and I think some are turning up. That's what we're all about. 

"We have another planned for February 25, if they go well, then we'll keep doing them," Michael said. 

The family is documenting Leo's journey on the Ticknemoff Facebook page where you can keep up to date with the challenge as it progresses. 

"In the last 28 days, Leo's page has reached 200,000 people, which I think is incredible. People are inspired by his story, it's been really nice. 

"We never knew what the goal was when we started but we wanted to put the message out there of what the outdoors has done for Leo's Tourette's and the response has been amazing so far," Michael said. 

If you're interested in joining Leo for one of the group hikes, you can find out more via the Ticknemoff Facebook page.

The meet for Rannerdale Knott will be in the car park at 8am on February, 4.
