Here's some thinking on the monster heat. These ladies are sort of what they are at this point, so I think we get what we have been seeing as far as tactics.
Stars: Touhy, Barnett, Plourde, Appleton, O'Sullivan, Elmore, Kazimierska
Could Surprise: Ramsden, Goldstein
Overmatched: Wilkinson, Freeland, May
Touhy and Barnett charge for the front, they are starting close together on the inside anyway. Barnett leads through 600 w Touhy going to the front on straight before 700 mark. Chasers are Ramsden, Plourde, Appleton and May. Touhy ramps it up on lap 3 stringing out the field. Touhy hits 1100 in 3:03. On the last lap the NW express of O'Sullivan, Kazimierska and Elmore move thru the field to get in the hunt.
Touhy wins in 4:06, followed by O'Sullivan, Plourde, Kazimierska, and Elmore in 4:07/08. Barnett and Appleton settle for 6 and 7 and small q's in 4:09.
-The field could deliberately close off Barnett and Touhy at the start taking them out of rhythm and forcing them to deal with a box, but probably unlikely.
-Elmore is a red shirt soph in her 1st outdoor season w hs pr of 4:53 improved to 4:35 indoor and now 4:08! She's most likely to slip up among front runners.
Ramsden has great pedigree and is most likely to surprise. She's do for a pr and could hang on to kt for a q.
Wilkinson has speed to burn, if she's lurking w 200 to go watch out. I just don't think she can hang on to this pace.
