Australian track cyclist Anna Meares plans to mull over whether to retire after a disappointing Olympics Games.
Meares could only finish 10th in the women's sprint in Rio on Monday after having to settle for bronze in the keirin two days earlier.
The 32-year-old, who has six Olympic medals to her name and became the most successful female track cyclist at a world championship last year, offered no guarantees that she would compete at the Gold Coast 2018 Commonwealth Games in her homeland.
Two-time Olympic gold medallist Meares said: "I want to give myself the opportunity to be removed from this environment. I promised myself some time to comprehend everything, and make a decision. I just wanted to get here and race.
"I'd really like to thank my coach Gary West. He has constantly motivated me through the high and low points. He is not just a great coach in sport, but in life as well. I'm a big girl now, but I was once a young girl with a dream. I'm proud to have lived that dream for 22 years."
Having competed for medals for so many years, Meares found it difficult to take being out of contention in the sprint on day 10.
"It's hard to go out in the 9th-12th places. I must admit, to finish 10th is pretty brutal. I knew my sprinting was going to be the hardest part for me in these Games, but I didn't expect to be that far out of the competition," she added.
"There is no one who will criticise me more than me. The perfectionist within me makes it hard to comprehend this result. For the first time in 22 years, I just couldn't get anything more out.
"Every time I've put these colours on I've ridden hard. I was just too far off the mark in this race. Every time I've raced I've gone out to win, but so has every other racer. I am extremely proud of what I did in the Olympics, but it's hard to end these Games with that result."
