Brooke Gillies has been a guide for fellow Scot Alison Peasgood for a number of years, representing Great Britain in the PTVI classification at various events around the world.
Gillies first competed with Peasgood in 2021. Having recorded a DNF at that year's European Championships in Valencia, the duo bounced back to take bronze at the World Championships in Abu Dhabi. A year later and Gillies and Peasgood were back on the podium, making amends for the 2021 European Championships by taking silver in Olsztyn, Poland in the 2022 edition.
A couple of weeks after their best result together they went one better and claimed their maiden win as an athlete and guide pairing at World Triathlon Para Cup Besancon. Their final race together before Peasgood took maternity leave was a bronze medal at the 2022 World Triathlon Para Championships in Abu Dhabi, making it two bronze medals from two World Championships in the UAE city.
Having started off as a swimmer from the age of seven, Gillies qualified to race at 15 Scottish Championships and also played football as a goalkeeper for Dunfermline Ladies Reserves. Following illness in 2015, she decided to take a break from the pool and found triathlon as an alternative to swimming. Having done her research into the sport, she set it as a new goal and entered her first swim, bike, run event in June 2016.
Prior to becoming a guide, Gillies had represented the Great Britain Age-Group Team where she finished fifth at the 16-19 World Triathlon Sprint Championships in 2017. The following year, she claimed silver at the European Championships in Glasgow in the 20-24 category.
Having suffered an ankle injury, Gillies recovered and got back to racing, including at domestic championships and has also competed as part of the British Triathlon Super Series.
