Ireland's Ciara Mageean has qualified for the final of the 1500 metres at the World Athletics Championships in Doha.

With the top five athletes in each semi-final guaranteed a spot in Saturday’s final, Mageean secured the final automatic qualifying place with a fifth-place finish.

The Portaferry athlete clocked four minutes 15.49 seconds as Sifan Hassan of the Netherlands crossed the line first in 4:14.69.

Mageean displayed considerable tactical nous, racing prominently in a contest run at a pedestrian early pace, and was well positioned to cope with the wild sprint finish that was always going to ensue.  

The ultra-versatile Hassan, who earlier in the championships claimed gold in the 10,000m, led home Shelby Houston of the United States, Rababe Arafi of Morocco, Kenya's Faith Kipyegon and Mageean.

The 27-year-old became the first Irish woman to qualify for the final of the event since Sonia O'Sullivan in 1997, with the Cork legend finishing eighth in Athens 22 years ago.  

The second of the semi-finals was run at a more genuine early tempo, which resulted in 11 of the 12 athletes who lined up registering faster times than the one recorded by Hassan. 

Jenny Simpson of the United States prevailed in a close finish in 4:00.99, edging out Canada's Gabriela Debues-Stafford and Britain's Laura Muir. 

Ethiopia's Gudaf Tsegay, Winny Chebet of Kenya and Uganda’s Winnie Nanyondo were next best, while a personal best of 4:01.52 was enough for Simpson’s compatriot Nikki Kiltz to secure the final qualifying berth for Saturday’s final.

Speaking to RTÉ Sport's David Gillick afterwards, a beaming Mageean said: "I'm over the moon. It's my first world final. I have worked a long time to get to this stage and I may seem ecstatic - I still have another race to go - but I ran that saying 'that's going to be my final'.

"To have an Irish vest in a World Championship final - we don't often have it - and I'm absolutely over the moon." 

Reflecting on how the race panned out and the conundrum posed by a soft early pace, Mageean said: "I planned on not being at the front. Anybody who knows me or watches me racing will know that I'm not a typical frontrunner, especially not in a major championship, so that was a shock.

"But if they want me to go to the front and hold up the pace, they have to go around me.

"I said to myself 'if somebody comes to your shoulder, you’re going to match the pace, if they try to go around you, you’re going to go with it’.

"There was a wee burn-up on the last lap.

"I was looking left and right, and I was like, ‘OK, I have this fifth place’, but there was a little bit of panic all the way to the line."

Looking ahead to Saturday's final in Qatar’s capital, which is scheduled to take place at 6.55pm Irish time, she added: "I’m going to give it everything out there.

"I always say 'get into the final and it’s anybody’s game’.

"I have a lot of respect for the girls out there, but I think I’ve shown that they need to have respect for me too.

"I’m going to go out there and I’m going to give them a hell of a time."
