Negative Splits...

Couple of things to look at from my very good run this morning.







This is data from my garmin GPS unit for my standard 5.8 mile run loop. Usually I feel good if I can do it in under 46 minutes. Today's time was 44:50, after really struggling on this same route a few weeks ago. The big difference was the temperature and humidity. It was nice and cool out this morning. Maybe around the low seventies. Things to note: in the table, each mile was faster than the previous one, this is called having negative splits and is what you want to happen in a race. I'll take even splits in the marathon. Even 9 minute mile splits gets me under 4 hours. The heart rate graph shows just a slow drift upward as the pace shows a slow downward drift. Getting those 2 lines to remain steady for up to 4 hours is the challenge of the marathon. I probably need my heartrate to stay under 155bpm and the temperature to be no more than 65F to be anywhere close to a PR in the NYC marathon.

Swam in the ocean Monday night, at Virginia Beach, off 55th street. We practiced getting the heartrate up as would happen at the start of a triathlon and then bringing it down after rounding the first buoy(while still swimming). It's good to see how this feels. My biggest problem is just keeping my head down and swimming. Instead I'm looking around trying to stay away from kicking feet and swinging arms.

Swam 1 mile last thursday.
Ran 9.7 miles last Friday(hot and high humidity).
Rode 57 miles on saturday.

As societies grow decadent, the language grows decadent, too. Words are used to disguise, not to illuminate, action: you liberate a city by destroying it. Words are to confuse, so that at election time people will solemnly vote against their own interests. -Gore Vidal, writer (1925- )
