As organisers undertake emergency repairs to ensure venues and accommodation are fit for purpose in time for the event, which runs from 3-14 October, three former Games competitors tell BBC Sport how the disruption may affect athletes. I've heard athletes may have to squeeze in two or three to a room in the accommodation block, which could be an issue.

Athletes compete at different times of the day and have different daily routines, so two or three people in a room could lead to sleep patterns being disrupted. If there are paper-thin walls to contend with, that will only add to the problems.I only ever shared with one other person during my athletic career. Some of the rooms I stayed in were small - you could hardly swing a cat - but at least they were clean and habitable, which meant I could concentrate on the job at hand. Some competitors will shrug their shoulders and get on with things, while others will voice their displeasure.

Athletes will talk about the conditions and what their rooms are like, which all distracts from what they should be doing - and that is focusing on winning a medal rather than worrying about whether a rival has a better room. And they now have a ready-made excuse should they fail to perform.
