A Colombian runner has lost a sponsorship deal after footage emerged of him kicking a dog during a race.

Jamie Alejandro was competing in the Saint Silvester Road Race, in the town of Neira in Caldas, Colombia, on New Year's Eve.

Video footage shows the moment Alejandro and several others are running up a street, while a brown dog runs to the left of them.

As the group of runners approach a corner, the dog tries crosses in front of them.

Alejandro kicks the dog so hard that it flies forward along the street.

The runners carry on around the corner as if nothing happened and the dog continues jogging after regaining its balance.

Alejandro later posted a video apologising saying: 'I did not consider my actions. I have no excuses and I do not justify what I did.

'I hope I can repay for this somehow, maybe helping dogs in the street. I will not be posting that on social media but I will know what I did.

'I am not justifying my actions but it was a moment of euphoria in the race. I was not thinking and I know I can be a brute when I am competing.'

However, his apology seemingly did not go down well as American sportswear company Under Armour released a statement yesterday distancing themselves from the runner and ending their endorsement deal.

The statement said: 'Under Armour has ended its relation with Jaime Alejandro after the video came to light in recent days.

'As a company, we do not tolerate any violence or behaviour that may harm or put animals in danger.'

Alejandro has not made a statement since Under Armour's announcement.

The Saint Silvester Road Race is a popular annual race which takes place on December 31 every year.
