Pavey was well below her best in Birmingham

Jo Pavey will decide in the next few days whether to enter the World Cross Country Championships later this month.

Pavey, 33, finished seventh in the 3,000m at the European Indoors after suffering a bout of flu.

"I'm not sure if I'm going to run in the world cross country," Pavey told BBC Sport. "I've not made a final decision yet.

"I would love to enter as it is such a great team event but I now have to focus on the 10,000m this season."

The World Cross Country Championships take place in Kenya on 24 March

Pavey, the Commonwealth 5,000m silver medalist, plans to make her competitive debut over 10,000m this summer.

The Devon runner aims to race over 10,000m at the World Championships in August, where she could be joined by new mother Paula Radcliffe.

It bothers me that I worked so hard and I've disappointed myself but it was just one of those days Mo Farah

Pavey heads to South Africa on Tuesday for some high-altitude training before turning her attention to the 10k at the European challenge event in Italy on 7 April.

"I want to run well in Italy and need to put some training in for that," said Pavey, who had been pre-selected for Britain's world cross country team.

"I need to try and get the world qualifying time for the 10,000m as I've not done one before, but I don't want to leave it as late as July in case I get injured.

"Paula may do the 10k or the marathon but I want to do it regardless of her decision."

European cross country champion, Mo Farah, also flies out to South Africa this week intent on putting his European Indoor disappointment behind him.

After finishing fifth in the 3,000m on Saturday, the Londoner is stepping up his preparations for the World Cross Country Championships.

"I'm looking forward to getting out there and getting away from what happened in Birmingham," Farah told BBC Sport.

"I'm disappointed, I know the Worlds will be hard work for me, but I have to do this."

Farah finished fifth in the 3,000m at the European Indoors

Farah, the European 5,000m silver medalist, was expected to get among the medals in Birmingham but a fall in qualifying badly affected his build-up to Sunday's final.

When it came to the final, Farah, who also picked up a minor calf strain, admitted he had run out of steam.

"I took a big blow in the heats on Friday and it was still in my legs," said Farah.

"It bothers me that I worked so hard and I've disappointed myself but it was just one of those days."

Farah is now focused on performing well in Kenya on 24 March - the day after his 24th birthday.

The Londoner became just the second Briton to claim the European cross country title last December.

But Farah is well aware that the Worlds present a much stiffer test of his abilities - last year he was the first Briton home in the 4km race but still finished 40th overall.

"It will be a loaded field at the Worlds," said Farah, who will only be able to contest the 12km this year in the new competition format.

"There will be about nine Kenyans, nine Ethiopians, nine Eritreans - and they will all be very strong.

"But at the same time I have to mix in with these guys and see what it takes because after that my focus is on the world outdoor championships."
