Olympic bronze medallist Katy Marchant was eliminated from the sprint competition in the first round on the second day of the Track Cycling World Championships in Hong Kong.
Olympic bronze medallist Katy Marchant was remaining positive despite her first-round elimination in the women's sprint on day two of the Track Cycling World Championships in Hong Kong.
The 24-year-old Leeds rider claimed Olympic bronze behind gold medallist Kristina Vogel of Germany and fellow Briton Becky James, who won two silvers in Rio but is absent from Hong Kong on an extended post-Games break.
Britain did not enter the team sprint on Wednesday's opening day as Marchant was the only female sprinter to travel.
The qualifying ride - a flying 200metres - established seedings for the head-to-head match sprints and the top four qualifiers received a first-round bye.
Former heptathlete Marchant qualified in 16th place and met 17th-fastest qualifier Lin Junhong of China in the first round.
The Chinese rider led out the Briton, who was unable to round her and exited the competition, but was looking at the bigger picture and the Tokyo 2020 Olympics.
Marchant said: "I'm really disappointed. I feel like I'm just missing a little bit of zing, which is something that coming off Rio is to be expected, I guess.
"It's hard to comprehend, but that's bike racing.
"I didn't get the roar when I got the number on my back today - maybe the fact it's not an Olympic Games or something in the back of my mind telling me that I'm not feeling great.
"Last time I was up on the world stage was in the Olympic Games and I was winning a bronze medal.
"I know to get knocked out in the first round is not what we expect from a medallist, but the preparation coming into this competition is about the process leading on to Tokyo."
Australia's Stephanie Morton was the fastest qualifier in 10.724 seconds, with Hong Kong's Lee Wai Sze and Vogel second and third.
Marchant clocked 11.151secs - "it's about where I think I am," she said - and she was content after her debrief with her coaches.
"It's looking really positive going forward," she added.
"They didn't expect anything more from me than what I expect from myself, so I think I'm in a good place."
Marchant is scheduled to ride in two more events here: Saturday's 500 metres time-trial and Sunday's Keirin.
She added: "I'm really excited to get back racing in a couple of days.
"I'm hoping the Keirin's going to suit me a bit better. Having no expectations, having not ridden (the Keirin) in Rio, it's a clean slate for me.
"I think the Keirin requires a little bit less zing than the sprint. You can get in the bunch, you can use wheels, you can use bigger gears, which tend to suit me. We'll see how we go."
Joe Truman advanced to the men's Keirin second round, effectively a semi-final, but Lewis Oliva was eliminated.
Truman finished second in his first-round heat behind New Zealand's Sam Webster to progress at the first attempt.
Oliva was third in his heat and dropped into the repechage, where only one rider advanced.
The Welsh medical student finished fourth as his World Championships came to a premature end.
Six-time Olympic champion Sir Chris Hoy had tipped Oliva for a podium place on Twitter in the lead-up to the World Championships.
Oliva said: "It didn't put any pressure on me as I was going really well in training.
"The training would have pointed towards that and so would have the run of World Cup finals this year and the World Cup medal.
"It is pretty sad coming out all this way and going out in the first round, but that's international Keirin racing.
"You can feel good, be going well but you can make some wrong decisions and end up on an early plane home."
