STARS from two of the biggest shows on TV will speed through Oxford as part of a 200-mile bike ride to tackle Parkinson's disease.

Game of Thrones star Enzo Cilenti and Downton Abbey actor Michael Fox will start their journey in Bristol on Saturday morning and will arrive in Oxford that evening.

After staying the night, they will continue to Cambridge where they end the race the following day.

The ride, known as BOXCAM 200, will raise money and awareness for charity Parkinson’s UK by travelling through three cities where groundbreaking research into the disease takes place – Bristol, Oxford, and Cambridge.

Mr Cilenti, who appeared as wealthy slave trader Yezzan in Game of Thrones, has already taken part in several cycling challenges for Parkinson’s UK for his father.

He said: “It’s great to be back on my bike for such a great cause.

"There is no cure for Parkinson’s and there’s no way to stop or slow the condition progressing – so research is vital to help put an end to the condition and help thousands of people in the UK.”

Mr Fox, who played Andy in Downton Abbey, is cycling for his aunt, who was diagnosed when she was just 42.

He said: “I’ve never done anything like this before, so it’ll be a new experience for me.

"I’m putting in as much time as I can to train and doing this challenge for my aunt is giving me the motivation I need to keep going.

“I know the charity is a huge support to thousands of people with the condition, so it’s great to doing something like this to give something back.”

The 200 miles the cyclists will cover represents every year that has passed since Parkinson’s was first identified.

Paul Jackson-Clark, director of fundraising for Parkinson’s UK, said: “This new cycle ride is the first time we have ever created an event that will celebrate the research already being done at sites across the UK, while also raising vital funds for the work to continue.

“We’re really excited that Enzo and Michael are taking part in this first ever BOXCAM 200 event. "We hope that people will be inspired to join in, donate or come along and cheer – helping us raise a record amount for better research into Parkinson’s."
