I slept in later than usual this morning, and when I got up my muscles were sore. An honest soreness, from my workouts of the last two days. I can tell the difference between "good pain" and "bad pain", having experienced both during my marathon training eight years ago. I can tell you, I never want to experience the five weeks of knee pain I did after my last long run of 18 miles. Not being able to sit down without tears in my eyes for weeks is not something I need to do to prove my athletic prowess. Yes, I could have prevented the worst of it with more stretching, but the truth is that nothing other than ego made me want to complete a marathon, which is an impressive feat but really an arbitrary distance. I really hope that I can limit myself to runs lasting no more than an hour this time around, because every time I try to go longer I end up frustrated or injured. At least I did finish a half-marathon back in 2000, so I proved that I can cover a distance that I'd previously thought impossible.
So as soon as I got up today I did another round of those functional exercises. The abdominal crunches really kill me; I've been totally neglecting that area of my body for most of my life. But strengthening my core is very important.
If I accomplish nothing else during my time away from work, I want to be able to say that I truly got fit, which is more than just a number on the scale. All those miles of walking on hilly San Francisco streets gave a false sense of accomplishment; once I was used to the effort, it no longer challenged me. I need to go outside of my comfort zone to get real results.
