currently 12-14 hours a week with an olympic scheduled for may and a HIM in the beginning of july.
Last year I had a bit of a breakdown with the hours necessary for IM training as I felt that all of my hubby's and my free-time was triathlon related and it just didn't make me happy so this year we've agreed to be done racing by early July and just enjoy the rest of the summer by spending more time hiking, rented an island house for a week out in the San Juans, camping, etc. I know we'll still train but it will be racheted down significantly or at the very least not take priority as it has a tendancy to do now.
The biggest change from last year to this year though has been my mental shift. Now if I don't feel like doing a workout because there's something else I want to do or simply b/c I'm tired and want to sleep I don't force myself to workout. It's made me a much happier person and ironically I find that I really put my all into those workouts I do go to so I actually think I'm in better shape right now then where I was this time last year.
Edited to add after rereading: I don't consider myself to be superfit. I was at that stage once in my life when training for Olympic Trials (obviously not in triathlon) but my sport was my single-minded focus and consumed every single second of my day outside of class. It was great to do that once in my life but I feel no great need to try and reach that level again at the risk of detracting from other things in my life.
