Glasgow 2014: Shelly-Ann Fraser-Pryce on African medal challenge

Jamaican sprint star Shelly-Ann Fraser-Pryce believes African athletes will provide her biggest challenge at the Commonwealth Games.

The Olympic (100m) and World (100m and 200m) champion has yet to decide which events she will take on in Glasgow.

"It will be hard," she said. "You have the African nations - Blessing Okagbare.

"There are a lot of athletes that are doing tremendously well that will be at the Commonwealth Games."

Nigeria's Okagbare - an Olympic bronze medallist in the long jump - finished third in the 200m and sixth in the 100m at last year's World Championships.

Fraser-Pryce, speaking to the BBC's Mark Beaumont, said: "Training has been going well. I won the World Indoor title a couple of weeks ago.

"That definitely shows that training has been in full swing and is going very well. I'm looking forward to it."

As well as multiple successes in the 100m and 200m, Fraser-Pryce has also medalled with Jamaica in the 4x100m relay in the past.

The 27-year-old was talking about her prospects for the Games while taking part in celebrations to mark the Queen's Baton Relay in her homeland.

The baton, which contains a message from Queen Elizabeth, is currently travelling around the Commonwealth and will play a key role in the opening ceremony of the Games.
