  • Did the Sprint in 2018

    Really enjoyable, good venue, easy to get to, close transitions and very flat so PB friendly
  • Did the Standard in 2018

    Really excellent event. This was my first standard distance tri and as a beginner I really appreciated the simple layout. I can also appreciate the more experienced triathlete would like that it's an opportunity to push pace and times.
