After the best Para-athletes lit up London during their world championships last week, the focus now turns to the world's top Para-swimmers as their worlds draw nearer.
About 550 swimmers from more than 60 nations are set to battle for medals in the Francisco Marquez Olympic Swimming Pool in Mexico City from 30 September to 6 October 2017.
As well as British aces such as Bethany Firth and Thomas Hamer, global stars like Brazil's Daniel Dias, the USA's Jessica Long and New Zealand's Sophie Pascoe will be in the pool.
And for the first time, the World Para Swimming Championships will be staged simultaneously with the Para Powerlifting Championships in the same city.
More than 360 powerlifters from about 65 countries will be pumping iron in the Juan de la Barrera Olympic Gymnasium.
Together the two events will comprise the 2017 Para Sport Festival.
Both the swimming and powerlifting venues have prestigious histories - they were built for the Mexico 1968 Olympic Games.
