Ellie Simmonds will be in action this weekend at the British Gas Swimming Championships in Sheffield.
The four-time Paralympic gold medalist will compete twice across the event - getting underway on Thursday in the Women's MC 400m freestyle event alongside Hannah Russell.
Her next scheduled appearance is on Friday in the Women's MC 200m Individual Medley, going up against the likes of Amy Marren and Chloe Davies.
The best of British swimming are on display at the event and looking to secure their spot at the World Championships in Moscow later this summer.
World medallists Fran Halsall and Liam Tancock claimed semi-final spots in their respective events this morning as they look to help put Team GB's swimming team's Olympic misery behind them and claim a spot in Russia.
They scooped only three medals on home soil last summer while their Paralympic equivalents fared much better, securing 39 medals in total.
