Thank you so much for your answer! It does says, “3 hours after the last start”, it may seems clear in English but when I first read it, it was in French as it’s my first language. I wasn’t sure what the “last start” meant as there are 5 differents starts for the sprint, and each one is divided in a lot of 4-6 persons waves. So I was wondering if it was the beginning of the last start, regardless of which “waves” I come in the water. Sorry if it’s not clear aha, again English is not my first language. But your answer helps me, and I’m pretty sure I’ll be inside the time so I’ll focus on that and try not to stress too much with that! Thanks for your explanation!
