VIDEO: F1 star Alonso races a horse

Updated: 

Fernando Alonso has taken to the track to race an unlikely opponent as Argentine Facundo Pieres opted for a four-legged mode of transport.

McLaren driver Alonso, who won two Formula One world championships on the trot a decade ago, raced against polo player Pieres, who was on board his horse.

The trusty steed proved a worthy opponent for Alonso's classic car and the Spaniard might have had some nagging doubts when the horse pulled into the lead.

But the 35-year-old - who you would have expected to win at a canter - was not behind for long and the two competitors were stuck together like glue until the finish line.

If it had been qualifying, they would have had to share foal position and Pieres' pet is now likely to gain a colt following.
