Bonding! Kate and Wills go head to head on race track with Harry

Los Angeles : There is a special kind of love that is shared between a husband, wife and brother in law. The amazing fact was witnessed in a footage which shows the Duke and Duchess of Cambridge going head to head in a relay race this afternoon alongside Prince Harry.

They all turned out to support a training day for runners who will be taking part in this year’s London Marathon.

Before the race began, competitive Kate tied back her hair in a bid to give tough competition to her husband and brother in law during the 100m sprint which took part at the Queen Elizabeth Olympic Park (QEOP) in London on Sunday.

Even though the 35-year-old Duchess failed, she gave a tough competition to her husband and brother in-law.

The winner of the race was Prince Harry, followed by Prince William and Kate Middleton who came 3rd. 

The Duchess looked gorgeous in her bright orange puffa jacket but it seemed she wasn't prepared to stoop to a pair of joggers for the training day as she turned up at the e vent wearing a pair of jeans.

The training day was organised for runners taking part in the marathon for Heads Together - an umbrella organisation spearheaded by the three royals.
