PITREAVIE athletics star Eilidh Doyle has jetted out to Rio as the countdown begins to her second appearance at the Olympic Games.

With the opening ceremony for the 28th edition of the sporting spectacular set to take place in the iconic Maracanã Stadium tomorrow night, the 29-year-old flew to Brazil on Tuesday ahead of her bid for glory in both the 400 metre hurdles and 4x400m relay.

Doyle, who is one of 15 Scots competing for Team GB on the track, is only the third member of Pitreavie Amateur Athletics Club to compete on the world's biggest sporting stage after Linsey MacDonald in 1980 and Ian Mackie, who ran in the 1996 and 2000 Games.

The Bath-based star will follow Mackie in becoming a two-time Pitreavie Olympian after racing in London four years ago, and the double Commonwealth Games silver medallist has high hopes of bringing home a gong from Rio.

Doyle secured her place in the GB squad for the 400m hurdles by retaining her British title in June and the 2015 European champion's sparkling form continued at last month's Diamond League meeting in Monaco.

In a high class field – which included newly crowned European champion Sara Petersen, who took advantage of Doyle's decision not to defend her title – she produced a stunning display to win the event with a new personal best, and Scottish record, time of 54.09 seconds.

That statement of intent ahead of the individual event has been mirrored in the relay environment, where she will be hoping to emulate the form that saw her crowned European champion in Amsterdam last month.

Running alongside Anyika Onuora, Seren Bundy-Davies and Emily Diamond, she helped the GB quartet dominate the final to add to the bronze won in last May's World Relay Championship to provide real belief that she can challenge for podium places.

Doyle said: "The top priority is obviously the hurdles, but the relay is huge too. It's good to have that endurance and if they want to use me, I'll be ready. I'm confident going into that (400m hurdles) competition as the hurdles field on the international stage is wide open this year. I've got to keep working hard because they don't just hand out medals to anyone, so I will be fighting for one.

"There's a lot more to come. If I get it right, I can definitely go sub-54 seconds."

Doyle will be aiming to better her performance four years ago, where she failed to progress from her 400m hurdles semi-final while finishing fifth in the 4x400m relay.

The athletics events at the Games begin on August 12.
