I was considering a 10miler for this Saturday (two 5mile loops near my house that I posted a few weeks ago), then I remembered that if I go around the other way, it throws in some hills (well actually, they're washes, but you still have to climb up the other side lol). I just graphed that route, and there's a ~80ft difference between min and max elevations. Interesting, I wouldn't think it to be that much of a difference. I see it as a mostly flat course, but the chart proved me wrong.

So, I'll be doing two loops of that on Saturday.

For the following Saturday, I was planning a 6miler on my usual hill course (this was before I remembered the hills on the 5mile loop). I graphed that one and it's basically a great big Dromedary camel's back. lol 3miles out and back, with a 200ft climb to the 1.5mi mark, so I'd be taking that hill twice. One last ~30ft hill at about 2.8mi, again taking it coming and going.

I just need to study these charts, get a feel for them (like I said, they don't feel like there's that much of a change; they feel/look flatter), and run them properly. Get some muscle-memory going on, and SD should be a breeze.
