The girls penned the light-hearted missive following the lads' incredible gold medal win against the Australian team last night.
It appears the men’s' team had accidentally strayed into the women's dorm before - and may well have done so again following a few celebratory tipples.
The good-natured warning reads:
"To the team pursuit men, congratulations. As we're guessing you're probably gonna be drunk by the time you read this, and a few of you have already come into our room accidentally - just a friendly reminder that this is not your room. So please don't try and get in at 4am.
"Love, the girls.”
"PS - If you're really stuck, your room is <------ that way."
A picture of the note was posted to Twitter by Owain Doull, of the men's team, with the message:
"Hats off to the girls they know us too well."
