yes any long tri must have a 10km swim.
I was originally trying to be nice thinking minimum 6-7k, then realised 10k would still only be 1/8 of overall race time!
Check out 255triathlon and you will see its not as flat as you think, 1000m of climbing in fact!
There are plenty of longer triathlons but none longer over a single day 
Iol that’s race takes longer than a day so the title still stands 
Dale welcome,
Your ears must have been burning!
1000m over 200km, must be a few speed bumps on the course.
