I've done multiple ultra-marathons in my time - 50-K, 50 miles and 100 miles (the most recent being the Leadville 100 - tough because the low elevation is 9500 ft and the high is approx 12500 ft). Most weeks average around 80 miles per week. Depending on what I'm training for and where I am in my training my weekend run will include a very easy (walk every hill) 10-12 hour run (and a fair amount of night training). A decent off-trail training area (I'm not too far from some great trails in the Shenandoah) is a must as running on trails will prolong your legs over these distances.
I've often considered trying to train for the ironman (i've done a few duathlons in my time - run/bike/run again). But as Serious said a few posts back, the 2.4 mile swim is more daunting to me than any of the 100s I've done.
If this becomes an endeavour of yours, good for you. There are many great books to help you prepare for the total committment it will take. And, as you can probably guess, this type of training is more about your mental strength (running on the rainy days, the freezing cold days, forgoing a night out to make sure you can start your 4 a.m. run) than your physical ability (that will come as your training progresses).
One thing I can tell you, though - in finishing an event like this (whether a marathon, ultra-marathon or multiple sport event), you really do feel like there isn't anything you can't accomplish. Competitions of this type don't care about your background, net worth, etc. And, you just can't purchase your way to the finish. It is one of those few things left where your success is truly determined by your effort and nothing else.
Take small steps to start and you'll be there before you know it.
Best of luck.
