FW Komen Race, Part II: Race report

This is the elevation chart for the race I ran yesterday, the Fort Worth Komen 5K Race for the Cure. You can see the big hill I blogged about. At about 2.5 miles in, this thing hits you. You turn off of Forest Park Boulevard onto Weatherford Street.
At this point in the race yesterday, I was averaging a 6:45 mile pace. Well on my way to setting a 5K pr.
Then I hit this hill. It was .58 miles. Elevation, according to my Garmin Forerunner 305, was 68 feet. So basically, I had to climb a five-story building. (Didn't Batman need to pull himself up a rope to do this kind of thing?)
It took me 4:21 to get up this hill, a 7:48 pace. My heart rate soared from 90 to 95 percent max. My total minute-per-mile pace slowed from 6:45 to 7:04.
I sprinted the rest of the way in to shave a few seconds off my total pace and ended up running the 5K in 21:56
That's an even 7 minute mile pace.
Lessons learned? I need more hill work. And there are plenty in the neighborhood I live in. The loop around Texas Christian University set of rolling hills.
And to think I was done with school.
