Jess joined the UK Sport Lottery Funded World-Class Performance Squad in 2015. She is originally from Leeds and is based at the Leeds Triathlon Centre where she is coached by Ray Butters. Jess won her first major international title in June 2017 at the ETU European Championships in Kitzbuhel and took a silver medal in both the individual and mixed relay events at the 2018 Gold Coast Commonwealth Games.
Known for her swimming and cyling power and speed, she upped her running in 2017 to be able to hang on at the front of major races, which helped secure her first ITU World Triathlon Series podium in Stockholm. She followed that up with third place finish at the 2017 ITU World Triathlon Grand Final race in Rotterdam.
Swimming is a key strength for Jess, having won a National Championships freestyle medal whilst competing for the City of Leeds Swimming Club. The Leeds United fan formally played golf at Wetherby Golf Club and football for Leeds United Ladies Academy before switching to her current sport. Her first experience of triathlon was a charity mini-tri, but her dad was already into the sport at that point so she was well aware of it.
A member of a sporting family, Jess' brother-in-law competed in the 3000m steeplechase at the Glasgow 2014 Commonwealth Games, finishing 6th. Her partner is called Jonny Wilkinson, although he is a gas engineer and Category 2 road cyclist rather than a World Cup-winning rugby player.
Jess represented Team England at the 2018 Gold Coast Commonwealth Games in April, winning a silver medal in both the individual and mixed relay event at her first major multi-sport games.
