An athletic endurance competition for couples comprising of three consecutive events. The two participants usually engage in the first two events, drinking & eating simultaneously over lunch or dinner. This is always then followed by no less than 36 hours of nonstop sexual intercourse with only brief pauses for the periodic consumption of more food and drink.

Originally inspired by the legendary Ironman Triathlon held every year in Hawai'i consisting of a 2.4 mile (3.9 km) swim, 26.2 mile (42.2 km) marathon run and 112 mile (180 km) bike race. Its current usage however has come to be a reflection & demonstration of the legendary sexual prowess of the normal Hispanic male or female.
Joe: Hey Luis! Wanna come to the beach with us this weekend?
Luis: Sorry man, I'm preparing Allison for her first Spanish Triathlon beginning this Friday night.
Joe: Oh shit dude, you're a total fucking Ironman!
Luis: Please save it Joe, I'm just getting started. Just wait till I really decide to break her in half!
