British Army athlete Captain Lauren Hall says she is "not scared" ahead of representing England on Sunday.
Capt Hall will return to the international scene after two years away due to injuries.
The runner will be competing in the Cross Internacional Juan Muguerza in Spain.
The athlete has been scintillating form for the Army in the past year and say she is ready to return to the national fold.
"I’m not scared at all. It’s cross country so I will put my heart into it," she said.
"I’ll do myself and my country proud hopefully.
"I was really made up because the past two years have been plagued with injury and illness.
"It’s been a long time coming since 2017 and getting those two international vests then.
"It’s so nice to finally get that recognition of my potential."
Capt Hall did find out about the call-up a few months ago but had to keep tight-lipped about the news.
She explained: "I did have to keep it a little bit quiet because I still had one race in December.
"Once I had done the 10k in Telford, that’s when I could tell everyone which is really good."
The runner hurt her hip while training and admitted her recovery has surprised even herself.
"Sport baffles my mind," she said.
"I couldn’t believe that literally eight months ago I couldn’t walk because I had hurt my hip in a training session.
"To come back in November and race at the GB Trials and literally be two places away from the European Championships.
"It just makes me realise that no matter the setbacks, if you believe in your potential you can get there."
The race in Spain will mark Capt Hall’s first international appearance abroad.
"The previous two international vests were in home countries," she said.
"I raced in Ireland and Wales.
"This one is my first one overseas and I’m really excited because there will be Ethiopians and Kenyans.
"It’s the biggest one I have ever done."
