The International Festival of Extreme Sports Battle of the Champions began in Saudi Arabia today, with a day of parkour action in Al-Ahsa.

The annual invite-only contest, which also features BMX cycling competitions, skateboarding and roller skating, saw Ukraine's Erik Mukhametshin win the day's climax of the freestyle pro parkour challenge.

The 28-year-old, who has his own YouTube channel showcasing his extreme stunts, topped the standings in the Al-Ahsa Oasis with a score of 99.00 points.

That saw him beat Romania's 19-year-old Pedro Salgado by just one point. 

Thirty-nine-year-old Dimitris Kyrsanidis, a two-time Red Bull Art of Motion champion, managed a score of 97.00 points for Greece.

Tomorrow will feature a mixture of skateboarding, rollerskating and BMX action, culminating with BMX freestyle park pro qualifying.
