I try my hardest to schedule things on easy days (Mondays and Fridays) or on weekends when I have the entire day, but it's not always possible. I have to go to the doctor when they have space. Tomorrow at 3 I have to go to Geneva and get my bike fit done because that's when they could squeeze me in. Next week I have to pick Andy up from a doctor's appointment because he needs a ride home. All of these things are things in my life that I can't blow off, and I need to be able to work my training around them instead of freaking out. So tomorrow I will go to work early, get to Geneva by 3, do my fit, and then go to the gym late. I won't like it, but I need the fit to be done so I will do it.
I think I do things like marathons and Ironman because I am an introvert. I like to stay busy but I don't like to be around tons of people all the time. This way, I get my solitude with all of my training but I get human interaction with the best kind of people out there - other triathletes! And the few friends that I do see on a regular basis are people who are similar to me and who understand what I do and why I might have time constraints. And they don't constantly pester me to go clubbing or something else ridiculous that I would never do.
