So I reckon that if I swim at least 15000m a week for 8 weeks, cycle 250 miles for same and run about 50 miles a week in the build phase of my ironman prep (weeks 13-5) then I should be on for Kona or there abouts (see older post somewhere). Problem is that represents 26 hours+ training a week never mind the getting dressed undressed washed prepped etc. Add to that some recovery time and we are talking in the region of 40 hours a week.
Devoted as I am to my goals I could not do this whilst maintaining a career, family and marriage and whilst to some it would appear that these are not limiters I do Ironman to add quality to my life and not to take away (macrocycle or big picture). To maximise my benefit from the training I do it is probable that I have a tendency to go a bit harder than is ideal in an effort to get more, but maybe this helps me to do just that.
I do know that I can nail about 17-20 hrs training in a working week when I have everything on song (the mesocycle). This requires all the usual planning and a clear limit to the timescale over which this will occur (about 4-5 weeks), otherwise the rest of the life starts to build up and things start to get in the way. I have also become much more disciplined in my response to niggles and injuries and I will readily not do a session if I think injury is a likelihood (although this last Autumn would suggest otherwise).
This might give 6-8 weeks of 10 hrs cycling 5 hrs running and 3hrs swimming which aint too be sniffed at(microcycle). Add a week or two where I push the limits a bit and who knows what I might achieve but I still think a breakthrough for me will come in my fifties (thats probably extending the definition of macrocycle a bit far) when my kids are at Uni and my life may be simpler.
So what I am trying to say in a long winded way is that I am starting to accept that the limits in my performance will be due to external limiters (time) but in reality it is the internal limiters that ultimately count: I like my life, family and career too much to let the necessary obsession overwhelm me. The problem is this gives me an excuse to accept a "lesser" performance because I did not have the time to do the training I would have liked, and this can be demotivating....
So I need to put up a goal. That will be 10 hrs 45 mins for Lanza including a sub 1 hour swim and a sub 6 hr bike (see last years results)... that should do for the motivation.
