The Women's 4 x 100 metres relay athletics events for the 2016 Summer Paralympics took place at the Estádio Olímpico João Havelange between 14 and 15 September 2016.
A T11 athlete may be entirely without sight, or be able to perceive light, but have no ability to see the shape of a hand at any distance.
Athletes in this category have a variety of visual impairments, but can typically recognize contours from a distance of 2 to 6 metres.
The athlete may have sufficient function to run but demonstrates poor balance.
These athletes do not have the capacity to remain still and they show involuntary movements with all four limbs affected.
