So yesterday I walked 34 minutes-walking down the road from my home. 17 minutes one way and actually 16.40 back. But I knew I didn't make it to the mile mark, so I was short of 2 miles overall.

Today I decided to walk to the mile mark, which wasn't that much further. So I walked the 2 miles in 35 minutes.

Edit: Forgot to add how I felt half way - (1 mile) kind of shaky. I thought it might be a blood sugar thing. I was aware of it for about half way back and then I didn't notice. I'm home and haven't eaten yet, I'm cooking lunch, and as I'm not feeling it so much, but also not exerting myself. As I wrote in my original post, I'm not so used to doing a lot-and I know it sounds lame, but that's the kind of thing I could use as an excuse for not exercising in the future.

If anyone reads this and knows why that happens-if it's something to worry about-should I just bring some nuts on a walk in case I get real shaky? I'd appreciate any info./suggestions.
