Getting Over Cricket's Barking While Tied Up

The "seperation" excercise- On Track Days, I like to park 2 miles from the track, run with Cricket to the track and then tie her up, do my workout then run the 2 miles back to the car. The only problem is she barks the whole time. If I have my ipod on really loud, I can drown her out but I don't think it is very pleasant for my fellow track runners.
To help Cricket get over her supposed seperation issue, Lee wants me to go in the backyard with 10 treats and a chair. I tie her up about 2 ft from the chair. I put the treats on the chair. I get up and give her a treat. I sit down, again. In 5 secs, I get up and give her a treat. I sit back down. I repeat this, doubling the time, every time. So, next time it is 10 secs, 20, 40.....and so on. I do this four times in a row. Next day, I go to another spot. Eventually, we go to the track, which is where I have the biggest problem. With this exercise, I'm supposed to eventually go to the track, with my chair and treats, run one lap around...give her a treat. Now, I'm not totally clear on whether or not I repeat this 10 times X 4. That's 40 laps around the track! Also, I'm not sure if I give her a treat even if she barks. What this is supposed to teach her is that I am always coming back. The 40 laps around the track...is that at tempo or marthon goal pace? I gotta ask Lee to clarify that one.
