the non training related outlaw thread is a classic if i do say so myself

so you can run miles - you do ultras ffs
you can bike miles.... (lejog is solid base traning)
your swimming is ok.......
do a couple of swims a week.... one for consistency, one getting slowly longer - add 100m a week and you will be at 3.9k by race day
keep the running ticking over,
but you are already fit enough here. as everyone else says, bike fitness is whats needed most in IM, so try and ride long once a week building up from x hrs to a 6 hr ride. If its 'easy'. then regular 6 hr rides each week / over distance rides are next
throw in the odd 30 min run off a long bike to get the idea of how slowly you will be running on race day.. IM running is all about not slowing down, not running fast
everyone is in a different place, but you sound like you have a pretty solid base.....
Do some specific training post your ultra, (ie bike, bike, swim, bike, bike and bike some more) and you will be fine
btw if you're speedy along with having endurance (and therefore gonna beat me) then all the above advice is wrong. You have no chance and should throw in the towel next year and start a john newsom 3 year plan
