Need Advice: Getting ready for a 15K

[dude]

I am running in a 15K (9.2 mile) on July 11th. I am training to maintain my muscle mass as much as possible while training for this. I am trying to figure out how to adjust my resistance training program. I know that I should probably do high reps to get my body ready for this distance but my goal is to run the race with my muscle mass that I have now. This is what I have come up with.
Monday
Deadlifts-10, 8, 6
Overhead Press - 5X5
Squats - 5X5
Seated Calf Raise - 2X12

Wednesday
Barbell Rows - 5X5
Bench Press - 5X5
Deadlifts - 1 set of 20

Friday
Shrugs - 5X5
Barbell Curls - 5X5
Dips - 5X5
Squats - 5X5 with weight from Monday
Standing Calf Raise - 2X8

Also, I would change up some of the exercises from time to time so that I don't get bored and keep the variety going.

Well, I'm not going into the split right now (I want to take a nap), but let me say this: The more muscle mass you have, the harder it is to run distance. Back when I ran HS cross country, I, and 2 of my teammates ran at over 175 pounds. When you're competing against 125lb true runners, you gotta work much, MUCH harder to perform in the same times.

Hell, I ran a 19:30 5K back then, consistently. I got out about a week ago and tried to run for the first time since last August (been doing bike instead), and my time had dropped to like 13 minutes for 1.5 miles.

Well right now I am working on high volume low intensity so I am running 6 miles at a 10min/mile pace 4X/week. The other two days I do cross training on the elliptical trainer or bike. I weigh 215lbs with around 10% bodyfat.
Also, my goal is to run at an 8 min/mile pace. I am definitely not planning on winning. This is the boilermaker and last year a Kenyan ran it with a 4 min and 39 second/mile pace.
