HE might be a youngster but he has certainly got a heart of a lion.

Ben Donahue, 8, is planning to swim 4.5 miles on September 1 to raise money for six-year old Jamie Inglis, a cancer patient he has never met.

The idea came to Ben after he overheard his parents and friend Sergeant Robert Records mention that Jamie, the son of a friend from Record’s army training days, is battling neuroblastoma, a severe childhood cancer.

Jamie beat the illness when he was just three but has since relapsed, now requiring €317,000 for treatment in Germany.

Ben will swim to raise money for Jamie while Sergeant Record, unwilling to sit idly by, will run a marathon the same day around the Rock.
