Earlier this year, 21-year-old Nora Lindahl walked away from the Swedish team despite sprinting for the country at the 2024 Olympics and 2025 World Championships. From the end of 2027 onwards, she will represent Finland, the country of her father's birth.
Now, 23-year-old Thid has also turned his back on Sweden, choosing instead to represent Thailand, where he has family roots on his mother's side.
With a personal best of 49.12 seconds over the 400m hurdles, Thid is currently third among active Swedish athletes, and a switch to the Asian nation gives him a better chance of reaching the 2028 Olympics in Los Angeles, though his main motivation for the change lies elsewhere.
"It's mainly because I don't trust SOK (Swedish Olympic Committee) and the risk of not being selected for the Olympics even though I deserve the spot," he said.
"It happens every time that qualified Swedes are not sent because the SOK has its top 12 requirement," he added, citing SOK's criteria that only athletes considered capable of finishing in the top 12 in their event at the Olympics will be selected for the team.
Luxembourg-born Lindahl gave similar reasons for her change of allegiance, claiming she had not been given the support she had requested from the Swedish committee. She reminded the Swedes what they would be missing by winning the 100m at the Swedish national championships on 24th July.
Like Lindahl, Alabama University's Thid will have to serve a suspension before he can represent his new nation. The standard period is three years, which would begin from last year's European under-23 championships, but he is likely to appeal for an exception.
"Now we have another talent fleeing Sweden for another nation and here it is clear what the main reason is," said Swedish Athletics' secretary general David Fridell. "It is something we must take very seriously in Swedish sports."
