It works out to an ~8:30 pace, which is right around the 50% age grade mark.. but we did a group warmup at a 10 pace for the first mile so the splits are a little bit off.  I've been running less than a year, so that should give you an idea of how terribad these hams are if they can't finish first over 7 miles with a 40 minute head start. To be fair, they were women who were also quite a bit older than I am, so despite the snail's pace, they probably worked harder than I did. Still, absolutely nothing to brag about.
