Birmingham Diamond League: Mo Farah & Greg Rutherford headline Grand Prix

Olympic champions Mo Farah and Greg Rutherford are among 21 world champions set to compete in the Birmingham Diamond League meeting on Sunday.

Farah takes part in the 3,000m while Rutherford competes against a high-quality long jump field.

In the women's 100m, British record-holder Dina Asher-Smith takes on world 200m champion Dafne Schippers.

Adam Gemili, who ran his first sub-10 second 100m here last year, faces fellow Brits CJ Ujah and Richard Kilty.

Why does it matter?

The sixth leg of the global Diamond League series, the event at the Alexander Stadium is a key competition in the build-up to the Olympics in August.

Diamond Race points will be up for grabs and athletes will be looking to secure qualifying standards for Rio.

What they say

Mo Farah: "This will be my first big European track race of 2016 and a great platform to test myself on the road to the Olympic Games in Rio.

"I know that having the support of that passionate home crowd will be a great motivator for me on the day and going into the Games."

Greg Rutherford: "This is the best field of long-jumpers in the world and will be the real start of my road to Rio. I'm really happy with the start I've made to my season and I'm hoping to jump even further than last year."

Former Olympic and world 400m champion Christine Ohuruogu: "I'm aiming for my fourth Olympic Games and everything has been going well in training. I've just come back from Florida which was nice and hot and then I come back here and it's cold!

"But it's always great to compete in the UK as the fans are so knowledgeable and passionate about athletics."

Anyone else I should look out for?

Kenya's 800m world record-holder David Rudisha will tackle the rarely run 600m.

Olympic champion Kirani James of Grenada competes against home favourite Matthew Hudson-Smith in a world-class 400m.

Kendra Harrison ran the second fastest time ever in the 100m hurdles in Eugene last weekend and will be hoping to go one better in Birmingham against a field that includes Olympic champions Sally Pearson as well as Britain's Tiffany Porter.

In the men's 200m, American Trayvon Bromell will meet Canada's Andre de Grasse for the first time since they tied for the bronze medal in the 100m at last year's World Championships in Beijing.

Olympic bronze medallist Robbie Grabarz (high jump) and fellow Britons Lynsey Sharp (800m) and Eilidh Doyle (400m hurdles) will also be in action, while the new Scottish 5,000m record holder Andrew Butchart features alongside Farah in the 3,000m, the final event.
