And the budding athlete is starting to make a name for herself, returning from the 2015 Australian Youth Triathlon Championships with a win under her belt.
She trumped fellow competitors in hot, humid conditions in Queensland last month to win the 15- to 16-year-old female race.
�That was good, exciting I think,� the Kinross College Year 10 student said.
�I came out top three in the swim and then there were three of us drafting on the bike and the rest of the group were together, slowly catching us.
�They caught us on the last lap so every girl transitioned together, so it was a bit hectic and then it was just down to the run.
�I felt pretty good in that run.�
Jess also came second with WA team mates Jonathan Summut and Luke Bate in the 16- to 18-year-old mixed teams triathlon relay.
Always a keen swimmer and runner, it was suggested she try her hand at triathlons.
�I think it was the State Selection at Champion Lakes,� she said.
�It wasn�t too long but I was happy because I did well in that one and I wasn�t really expecting much.
�It�s a lot of training. It feels good (when you finish), especially when you do well.
�Probably the swim or the run is my favourite.�
Jess trains about 10 times a week, with Stuart Denton overseeing her triathlon and training plan. She cycles with him and takes part in transition practice and ocean swims.
Matt La Spina is her running coach and Dani Dielsen her swimming coach at Breakers Swimming Club.
She is now working towards the School Sport interstate triathlon in NSW at the end of the month and some local competitions.
Mum Louise said she loved seeing the joy on Jess� face when she finished a triathlon.
�I love watching it and I love watching the relays,� she said.
�The school has been really fantastic. All of her teachers will extend an assignment if they have to.�
