North Yorkshire athlete Richard Buck insisted he is not too disappointed at only finishing third in the 400 metres at the Aviva UK trials in Sheffield.
The City of York runner was boxed in at a crucial stage of the race and was unable to post a World Championship qualifying time.
"I ran the rounds really well, they were really good, well-controlled runs," Buck told BBC Radio York.
"Now it's about recovering from that weekend, both physically and mentally."
Buck's next challenge will be in the Birmingham Grand Prix on February 18 to 19, where the second Great Britain place for the World Championships will be decided.
"We were only doing the indoor (season) as a milestone to see how training was, and we've seen that training is going really well, so we're happy with it," he added.
"It will be great to go to the World Championships, because that was what I set my targets for originally when I decided to run some indoor races.
"Ultimately our goal is the Olympic Games, so in the big picture it's not important, but in terms of short-term objectives it's the last chance to get the qualifying standard."
