A HARRY Potter star will be taking on one of his biggest challenges yet to raise funds for Thames Hospices' new facility.

James Phelps, best known for playing Fred Weasley in the Harry Potter films has signed up to take on the Big Mountain Challenge road biking event in the French Alps.

The four-day cycle challenge will see participants riding alongside the actor on difficult terrains.

Riders will ascend the equivalent of Mr Kilimanjaro at 589 meters or for more advanced cyclists, the height of Mount Everest at 8848 meters over 3.5 days.

James Phelps, said: "I have known Thames Hospice for several years and have always admired the incredible support they offer their patients and families.

"When I heard about the new hospice build, I was delighted to do my bit to support it.

Riders will get the opportunity to conquer Tour De France style hill climbs, or take gentler routes while raising money for a good cause.
