Mr. Skinner (too busy to read this blog), you have a lot of catching up to do.
Newport to Bolsa Chica and back=20 miles. That runner's high you've heard so much about is a hoax; well, maybe not a hoax, but very short lived (it was completely gone at the half way point...with me 10 miles from home).
If you ever run 20 miles, do not make any plans for the rest of the day. You will not get said plans done. Unless your plans are to watch Oprah and fall asleep.
