Sights were set on gold for 2018 Winter Paralympics

Seven medals and two athletes. Great Britain's medal success at the Winter Paralympics was dominated by two visually impaired skiers and their guides. Two skiers, Menna Fitzpatrick and Millie Knight, both 19 years old, along with their sighted guides Jen Kehoe and Brett Wild brought in one gold, four silver and two bronze medals between them - reaching the GB target with their efforts alone.

What are the challenges of taking on the speed and danger of alpine skiing when you have limited visibility?

ParalympicsGB has shared the data and routines of their athletes to lay out the gruelling life and remarkable achievements of a visually impaired skier.

How much can visually impaired skiers see?

Visually impaired skiers are split into three classifications - B1, B2, B3. B1 is for athletes with a stronger visual impairment, with B3 the lowest visual impairment. This is similar to the summer Paralympics with athletes coded into T1, T2, and T3.

Fitzpatrick was born with congenital retinal folds and has no vision in her left eye and limited vision in her right eye, while Knight lost most of her vision as a child because of a rare condition known as toxocariasis.

Both are classified as B2 athletes, while their team-mate Kelly Gallagher, who won Britain's first ever Winter Paralympic gold medal during Sochi 2014, has oculocutaneous albinism and is classified as B3.

Generally, the athletes have around 5% vision and can see to a depth of about two metres, but this varies between peripheral and partial sight and only picks up changes in some colour, shade and shape.

Each racer has a guide, who skis in front wearing a bright orange bib and communicates instructions through a bluetooth headset.

All three classifications race together, but the times are factored depending on the severity of the disability - so the clock ticks over slower for B1 athletes and quicker for B3.
