Sioux Falls Half Marathon Training Run?

Well I had this blog drafted up a month or so ago, and after the GoFar Half Marathon debacle/poor performance and conditions I'm rethinking my game plan.

Option A:  Next weekend, I'm running my tenth consecutive Sioux Falls Half Marathon. After having just raced the Fargo half, I won't be racing Sioux Falls, but I would like it to be a solid marathon training run. I rarely sign up to run races instead of racing them, because $$$ I can run 13.1 miles for free. But because I'm trying to run this race the most years consecutively, I need to work it in to my schedule.

So I'm curious, what's your favorite marathon training workout for 13.1 miles?

I know Pfitz has a 13 mile long run with 8 miles at GMP. When I used the RiverRat Half Marathon as a training run this past spring, Jaseface suggested I do 3 miles at long run pace followed by 2 hard miles, until I finish the race. I would like to do a harder effort than that, however, as that was done knowing I was racing a half the following weekend, and wanted to be recovered.

Should I go with the Pfitz workout?

Is there another one you'd recommend for me?












OR

Option B:

On the drive home from Fargo, I was still pretty bummed about my race performance. I randomly looked at the extended forecast for the Sioux Falls half and learned that it was projected to be a low of 43 degrees on race morning.

Oh.

That may change things.

 I could re-attempt my game plan for the GoFar half in Sioux Falls. I have two weeks of peak training after the SF half before I start tapering for Bemidji. Is this racing too close to marathon race day? 5 weeks apart? Obviously Bemidji is my #1 priority, but I know a solid half race would really get my mental game straight and ready to tackle 26.2.

Help.

If the forecast changes at all (skewing towards hot or humid) I will immediately go back to Option A with no question.
