Hello friend,
The ayahuasca will not affect you physically in the tournament, specially 5 days later. I have done demanding physical activities a couple of days after ayahuasca and was just fine. If you have a strong demanding experience and don't recover with good food, hydration and sleep, you might be a somewhat tired the next day, but even then it doesnt always happen, sometimes you have more energy, due to the "spiritual reset" or however you wanna call it
5 days later, though, no issue at all.
What kind of setting are you taking it in? Do you have someone to care for you?
Be well!
