Superman commitments may well have been put to the side on Saturday morning, but Henry Cavill’s latest public appearance was no less heroic as worked up a sweat on The Rock Run in Gibraltar.

British star Cavill, 31, was joined by brother Nik Cavill – a Lieutenant Colonel in the Royal Marines – for the 350th anniversary run, which sees sponsored participants undertake an exhausting five kilometre uphill climb for charity. 

Sporting the fundraising initiative’s luminous yellow T-shirt and black shorts, the actor, currently working on forthcoming epic Batman V Superman: Dawn Of Justice, ran alongside his brother and 40 other competitors as part of the fundraising initiative, which generates money for the Royal Marines.

‘I will remember this day fondly and probably with a little bit of physical discomfort, which only seems fitting considering what this day represents,’ he said.

Event organiser Alan Hardy admitted that he was delighted to see the actor take part and hoped he would enjoy ‘what Gibraltar has to offer.’

Come on Henry! The British actor held his own during the exhausting five kilometre run close to Gibraltar’s sweeping coastline  

‘Gibraltar will always hold a special place in Royal Marines history,’ he added. ‘We have organised a fantastic weekend of fun and celebrations for participants and the locals of Gibraltar.’

The event precedes a Memorial Parade, to take place on Sunday, followed by cocktail reception attended by the run’s 30 top fundraisers.

Meanwhile filming is scheduled to continue on Batman V Superman in Detroit through the end of summer, before moving to Chicago in October, with the movie scheduled for a March 25, 2016 release.

Thoughtful: Henry looked serious as he explained his role in the epic race during an interview 

Michael Uslan, the film’s producer, has revealed that Bruce Wayne, aka Batman, played by Oscar winner Ben Affleck, will be in his 40s in the dark tale.

While many fans were in an uproar over the Argo star being cast in the role, Ben recently opened up to Entertainment Weekly about the criticism.

‘Everyone’s entitled to their opinion,’ he said before adding, ‘I wouldn’t have taken the part if I didn’t trust my instincts in terms of the filmmaking.’
