The 18-year-old swimmer, from Marsh Lane, qualified to compete at the British Nationals in the 200m, 400m and 800m freestyle, the 200m fly and the 5K open water swim. She won gold in the 4x200m freestyle relay and the 5K open water swim.
Jessie says: "I currently train at City of Sheffield swim squad nine times a week, including four morning starts at 5.30am and five evening sessions, starting at 4pm.
"I do nine swim sessions and four land work sessions. My land work sessions consist of medicine ball workouts, stretch cords, body weight and weighted exercises. After each session I also stretch.
"This season I have qualified for the British Championships (Olympic trails) in the 400m and 800m freestyle. I hope to improve my rankings and personal best times at this competition.
"I also hope to qualify for the senior finals in both events. I am also close to qualifying in the 200m freestyle and the 200m butterfly, which would be a great achievement for me.
"Last season I won the Nationals open water in the open age group. This season I aim to improve my open water further. I will do this by competing in more open water events.
"I plan to compete in the Great North Swim elite race at Lake Windermere in June. Last season I came fourth in my age group and ninth overall, just missing out of qualifying for European Juniors in Switzerland.
"My sporting ambition is to qualify for a Senior Great Britain team and represent my country."
