Yikes, a reason to embrace the treadmill?

Media: Overexposure
Yikes! A lot of runners don't like treadmills, referring to them as "dreadmills." They're kind of monotonous and they don't teach you to monitor your own pace.

But maybe there's a place for them after all. Outside running may be more scenic, and it may train your pacing better, but it's not without hazards: cars, air pollution, bad weather, and so on. Skin cancer, too.

At least skin cancer can be avoided by using lots of sunblock.

Not so fast, says a Runner's World article. Sunblock works, sort of, but it's not close to 100 percent protection against damaging UV rays.

Per the Nature article cited in RW:
Here we show that sunscreen (UVA superior, UVB sun protection factor (SPF) 50) delayed the onset of UVR-driven melanoma, but only provided partial protection.
Partial protection is better than nothing, of course, but it's still only partial.

Well, I ran my 11 miles this morning on the treadmill. Yeah, 11 miles was pretty monotonous. I was planning on 12+, maybe even 13 while watching "The X-Files" movie, but just as the movie started wearing down after about 90 minutes, so too did my mental fortitude.
