Gemma Steel has claimed that Great Britain are close to ending Kenya's dominance of the World Cross Country Championships.
Kenyan athletes have won the women's title in all of the last four championships, but Steel has been training in a sport laboratory in Loughborough that simulates high altitude to help in her preparations.
"The Kenyans do dominate but we are catching them up because of advances in technology," Steel told BBC Sport.
"It means we can compete with Kenyans and Ethiopians so they don't have as much of an advantage."
Steel claimed gold at the European Cross Country Championships last year.
