I would think your girls are more than old enough and responsible enough to mow the grass.
3.75 miles today in 39:26. That's 10:29 seconds per mile. It would appear that lightning is an effective pace training tool... I ran fast and hard to avoid getting struck by lightning. I was just past the 2 mile mark (read: 2 miles from my office) when the lightning started. I was within a half mile when the downpour started. I like running in the rain - I really do. It's refreshing and cooling... but, I dislike running in downpours b/c then sweat runs into my eyes and I HATE it when my shoes get wet - even my vibrams, b/c then they take on a musty smell. Guess I'll be washing them tonight so they're dry and not smelly for tomorrow's lifting session.
Otherwise, super awesome run. I felt strong and my calf behaved. No talking from the calf at all. My foot barely hurt, but again, it barely hurts when running - just while walking (wtf??? I don't understand that at all!). I felt strong and able. And I was enjoying it.
Mile 1 pace: 10:34
Mile 2 pace: 10:37
Mile 3 pace: 10:49
Mile 4 pace: 9:47 (for .76 miles)
Interesting... I thought I would have had negative splits (meaning each consecutive mile was faster than the last) given the lightning, but apparently not.
Anyhow, great run.
