He's not just a pretty face! Heart-throb Josh Duhamel leads a group of youngsters in a two mile charity beach run

He may be a heart-throb movie star, but there's more to Josh Duhamel than a pretty face. 

The 40-year-old actor led a youth charity fun run for the third year running on Sunday, in aid of the Red Cross.

Josh sported the charity's T-shirt and black baseball cap with black jogging bottoms as he joined a group of youngsters in the two mile effort on Santa Monica Beach.

Josh was clearly enjoying himself today, sprinting across the finish line raising both arms in a victory salute. 

In March last year and January of 2010, Josh led thousands of runners and raised over $200,000 for both Japanese and Haitian earthquake relief efforts. 

And donations collected at this year’s Youth Run will go towards the American Red Cross PrepareSoCal campaign which helps Southern Californians get ready for disasters.

Third time's a charm: Josh has held the charity run for three years in a row

'I do the youth run because I feel that younger people may not be able to donate a lot of money but that doesn't mean that they can't contribute and make a difference,' Josh told the Red Cross website.

'Bringing students of L.A. together for these events not only raises a lot of money, but also raises the spirits of those affected by any disaster and empowers everyone young and old.'

There was no sign of Josh's wife Fergie at the run, although she was spotted in Los Angeles on Saturday as she attended the opening of a high end Walgreens pharmacy in Hollywood.
