After a week off while traveling, I have done runs of 3.1, 3.5, and now 4 miles in the past week. It's gotten really hot here again (winter is over, such as it was), and the sun is coming up earlier, so I have found that if I run on the (unpaved) road rather than the beach, I get more shade. The trade-off is less scenery and breeze, and parts of the road are rocky and not so kind underfoot -- but anything is better than running in full sunshine.

I'd like to stick with the 4 mile distance for awhile, then hopefully increase a bit more if the heat doesn't kill me.
