That is the magic number.
I've done this before and I'm going to do it again. But this time with more discipline, rigor, and overall dispassionate intelligence.
To race a Ironman fast I was doing 20-30 hours of training a week. That is NOT including time getting your gear together or breaking it down. It doesn't include stretching or showering. It does not include eating.
That's 20-30 hours of straight aerobic and anaerobic conditioning on the clock.
Mileage is something most athletes dispense in an effort sound impressive. But where are you doing your mileage? Florida athletes can't talk to Vermont athletes about mileage.
Two different languages there.
But we all can comprehend 25 hours of quality lactic threshold enhancing swimming, biking, and running.
5 hours a day - 6 days a week. 30 hours blocked off on my calendar.
Inviolate times. Sacred intervals sequestered from the day's stuff.
This does not mean that I will train 30 hours a week every week. It means I can. And it's on me to follow through. No excuses but personal irresoluteness.
I made it available to myself: my goal.
I can choose to sleep in or eat donuts during said 30 hours.
But that's my failure and my life to live.
I'm taking ownership.
