"I always tell everyone at my school that my sister remains my greatest inspiration."

Hannah Watson smiles warmly while looking at her older sister Aimee with clear admiration.

The Cardiff siblings are getting ready for the Hyrox World Championships in Stockholm, Sweden, while managing their roles as teachers alongside their sporting goals.

Aimee, 25, began Hyrox two years ago to maintain fitness during her football off-season.

Few transition from saving shots against players like Ella Toone and Lauren Hemp to performing burpee broad jumps.

Aimee played as goalkeeper for Wales Under-19 football side and also represented Wales at Under-19 level in cricket.

Yet Hyrox became her focus, particularly after involving her sister Hannah, 22.

"Racing together as sisters sparks something powerful inside," Aimee told BBC Sport Wales.

"My debut Hyrox was a solo event in London.

"I decided to just show up and do my best without knowing much, but I finished it.

"Next I asked Hannah if she wanted to try the doubles."

"Suddenly we entered our first pro doubles and ended up on the podium."

Their age-group victory at the 2024 Manchester Hyrox earned them qualification for the World Championships.

They placed 37th in their age group at the Chicago event, finishing in one hour, three minutes and 56 seconds.

"Many in Hyrox aim to reach the top and that takes time," Aimee said.

"We are ready to work through the process, stay committed and discover our potential.

"Training focuses on daily consistency and building the necessary volume.

"Our coach now helps us reach goals we once thought impossible."

This year they aim to finish under the hour in Stockholm.

"Our World Champs target is quite ambitious," Hannah said.

"If we miss the sub-hour mark we will keep striving and look to enter major events next year.

"We hope to reach the podium again and qualify for the 2027 Hyrox World Championships."

Aimee and Hannah balance their Hyrox aims with teaching duties.

Aimee works as a PE teacher and girls football lead at Royal Russell School in Croydon, while Hannah is based in Cardiff completing a PGCE after graduating from Swansea University.

Despite living apart they continue to motivate one another.

"It can be challenging but we stay very supportive," Hannah says.

"We message each other around 5am most days saying how tired we feel."

"Fitting in training and recovery around a heavy workload has been demanding but we have reached this point."

They also draw motivation from fellow teacher Lauren Stockley who trains at the same Newport gym.

Stockley will race in the Elite 15 Women's Doubles with Charlie Searle after a second-place finish in Warsaw.

"Watching her compete in Cardiff made us want to follow that path," Hannah said.

"She inspires us greatly and shows the dedication the sport requires."

Aimee agrees with her sister.

"The sport offers role models and for us that is Lauren, especially as a fellow Welsh athlete," she said.

Although training is demanding Aimee would not change it.

"It feels like having two careers yet it is what drives us," she added.

"At weekends we train together and push through tough sessions by encouraging each other directly."

"Above all the sport has strengthened our bond beyond the physical gains."

Hannah believes they have never been closer than while competing side by side.

"We have never been closer and we often say we are each other's best friends. This sport has truly brought us even nearer," she concluded.
