Paralympic champion Jonnie Peacock has welcomed the challenge of Brazilian Alan Oliveira, who has recently taken his 100m T43/T44 world record time.
Oliveira ran a time of 10.77 seconds in Berlin two weeks ago, outstripping the Brit's effort of 10.85 which was set last year.
Peacock competes in the T44, for athletes who are single below-the-knee amputees, but the classification is often combined with Oliveira's T43, for double below-the-knee amputees.
The 20-year-old from Doddington, near Cambridge, beat Oliveira into seventh at the Paralympic Games last summer.
"People are running faster this year that they were last year which is great," Peacock told reporters.
"I'll quite happily lap up these guys running fast - it pushes me along and makes me become a better athlete."
American Richard Browne, silver medallist in London, has also showed he can close the gap on Peacock by match the Briton's record earlier in the month.
While Peacock's rivals have been improving their times, the British sprinter has been concentrating on his return from an ankle operation performed after the Games and adapting to a new, shorter blade.
"It's going to be an interesting year for me," he said. "I've moved coaches and location, there's a lot of change for me.
"I basically got no winter whatsoever, so we're trying to compress the whole yea down into six months. It will be tricky but interesting at the same time."
Peacock claimed victory on his return to action, winning his first race since the Paralympics: the 100m at the Great CityGames in Manchester, taking 11.46 seconds.
