About Me

I took up triathlon in 2015, starting at the grassroots doing sprint and standard distances. Having raced at an amateur level at the World Age Group Champs (5th Overall) I decided to step up to Middle Distance the following season.  My first Middle Distance was IM 70.3 Calgary which I took the overall win at. From here I won the 2018 National Champs.  2019 saw my breakthrough to the Professional ranks securing four middle-distance podiums and 16th at the World IM 70.3 Champs, with only 4 months of full time training behind me.

2020: Head down and trained throughout focussing on the Ironman distance, this culminated in a course record at Ironman Florida with a sub 3hr off the bike marathon. Now I am ranked as the 3rd fastest ever British female. 

2021: Ironman Tulsa did not disappoint. Less than adequate swim, fought hard on the bike (outside of comfort zone), rewarded with a 2hr49 marathon (5th to 2nd). 

2022: Eyes on the prize - the Ironman World Championships. My debut.
