Running with the big boys

I've run with the Tuesday morning Luke's Locker folks long enough to know some of their names. As it turns out, many have either run the Boston Marathon or have qualified to run Boston in 2009.
Noreen, who normally leads the group, has run, I believe, more than a dozen marathons and Boston is one of them. Richard and Kimberly have qualified to run Boston next year. I'm not sure if Dave or Krista have qualified for Boston, but Krista is usually the fastest runner in our group and so I wouldn't be surprised if she did.
So, I figure the more I run with these real marathoners, the faster I'll get.
And it seems to be working.
This morning was our 6-mile tempo run. I finished in about 46 minutes, which is a 7:40 minute-per-mile pace. This is definitely the fastest I've ever run in training, but I didn't feel like I was "going all out" That's encouraging, because the pace is faster than my 2007 10k time at the Cowtown Marathon, and just a few ticks slower than my 2008 10k time at Cowtown.
Looks like I might be ready for a 5K pr. I'll keep my fingers crossed and register today (after I file my taxes of course) for the Komen Race for the Cure at Sundance Square in downtown Fort Worth.
Cheers.
