The 29-year-old Otley racer’s sole aim for 2019 is September’s Road World Championships in her native Yorkshire.
And Deignan, who under her maiden name Armitstead won the 2015 world title, plans to retire after a third Olympics in Tokyo, hoping to have created positive memories after a fraught Rio Games in 2016.
“I wouldn’t be happy to leave it with that Olympic experience of Rio,” said Deignan, speaking at the Rouleur Classic in London.
“I want to be a fan of the Olympics again. I want to watch it and love it.
“I don’t want to have painful memories of it. Tokyo’s my opportunity to do that. Whether I’m successful or not doesn’t really matter.”
Rio hurts her because of the build-up. Deignan, who won Great Britain’s first medal of London 2012 with silver in the road race, faced a two-year ban for missing three drugs tests. When news of her successful appeal seeped out prior to the Rio Olympics after the Court of Arbitration for Sport threw out UK Anti-Doping’s charge, many questioned whether Deignan should take to the Olympic start line at all.
Then the reigning world champion, she had been among the favourites for Olympic gold on Copacabana Beach. After a disrupted, agonising build-up, she finished fifth.
“That was just horrendous, the whole experience,” said Deignan is enjoying a happier experience as a new mother. She and husband Philip, a Team Sky cyclist, had daughter Orla on September 23 in Harrogate.
