So I run several times a week. Usually every other day. I go running in Rancho San Antonio near my home. Usually just under three miles. Some uphill and some downhill and some flats. Several weeks back, I was running and thought about what it would take to run across America. After all, Interstate 80 runs from San Francisco all the way to New York City. 3000 miles at three miles a day. A thousand days. Just about three years. I could do that, easy. Be kind of hard to only do three miles a day, though. I get through my three miles in 20-30 minutes, usually. I could probably slow down a bit and do 30 miles a day over the course of 10 hours of stops and starts. That gets it down to 100 days. Start in San Francisco in April with nothing but a running outfit and a credit card, then run and walk the whole day. Go to sleep whereever you're at and do it again the next day. Might be able to make it to Manhattan for the Fourth of July.
That seemed doable a few weeks ago (even if a little crazy). Lately, though, it's been harder to get up the hills, and even going down the hills has been awkward and sluggish. Now, running across the country seems not only crazy, but impossible. The hardest part of exercise is willfully putting myself into a state of discomfort. I know that I'll feel good when I'm done, but overcoming that inertia is the biggest obstacle. Once I'm going and I'm away from the house, then it's easier to go, but those first several scores of steps are hard.
