Aspiring international cox Imogen Dalivalle is waiting to hear whether she has gained a place in the Great Britain squad.
The Cheltenham Ladies' College pupil attended a training day on Sunday hopes to have performed well enough to be considered for the Great Britain Junior eight crew.
Being invited for the trial is the latest step in a remarkable rise for the 15-year-old, who only took up the sport in the autumn of 2011.
"I hadn't even thought about pursuing a future in rowing and considered Lacrosse to be my strongest sport," said the UC5 pupil.
"But then we had an inspirational talk by Zoe De Toledo (Oxford University and former GB Junior Cox) at the college rowing dinner and I realised that I could do it.
"Zoe has become my mentor, we speak regularly and she gives me lots of advice on how I can keep improving."
Imogen recently won the Veterans Head of the River on the Tideway, placed 12th out of 44 crews at the Fours Head on the Tideway, and won Gloucester Head.
On Sunday Imogen, who coxes for both the college first boat and Gloucester Rowing Club, was at Caversham to attend the GB event with fellow elite performers on Sunday.
She is one of 15 girls vying for a place in the boat for the World Championships in Lithuania next year.
Many of those she is facing are 17 or 18, so she faces a tough task to secure the berth.
"I'm quite a bit younger than most of the other girls, so I have to peak a lot earlier than them and stay on form for longer," she said.
"Even if I get picked now, all the spaces in the boat can change right up until the championships begin, so there are no guarantees.
"I just have to keep doing well in all my races and hope to stay on form."
