Notes
On the plus side, I was a bit fast on the 1ks. I felt good on most of them -- the only one that felt not as great was #4, but most of that one was a gradual uphill.
On the downside --- I started thinking towards the end that while it wasnt too tough to do a 1k at 8:30 -- I'm not so sure I can do that for an entire half (the half marathon equivalent of a 3:55 marathon is a 1:51:40, or an 8:31 pace.....). Of course, I was having those negative thoughts during my 4th 1k which was the tough one.
