Tougher than ironman?

As my wife is away for a few days yoga, I'm looking after the kids. So while trying to work from home, I double as a regular taxi driver to the golf, the shops, horse riding and swimming. I have to get the shopping and prepare dinner at 2 different times while catering for one semi-vegetarian! It's now 9pm and I'm sitting down for the first time.
So no training today although I feel I've been through a major workout. Tomorrow morning, after the drop off to the horse riding and before the shopping for new trainers for my son, I'll squeeze in a 3 hour training session.
No wonder my wife does yoga to recover from running a house and kids - on a full-time basis it's possibly tougher than ironman but don't tell her I said so"!
