That was my finish. To be fair she's almost six and it's tough to say exactly where she was: she cut the turnaround which saved a few hundred feet and cut across people's lawns on a few turns. She also finished behind me because I sprinted ahead at the end to snap a picture of her crossing, but F* me, it was so cold my phone had turned off so I didn't get one.
Putting it all together I'd probably put her in the mid eights.
They do a walking day once a week at school where kids try to walk a mile on the track with various special walkers: police officers, firefighters, mascots etc. On days when she's not screwing around with her friends (which is most of them) she'll run with the pack of runners and they consistently hit 6 or 7 laps in the 15-18 minutes they have. She'll pace me on 5-6 mile runs with her bike and at the end I'm dying but she throws her bike down and go and runs around in the backyard for another 30 minutes.
But having said all that I really don't want to encourage her to run road races until she's older. Once a year is fine but kids joints aren't all developed so I'm concerned about what an actual training regimen would do. A mile and a half on the school track is not the same as a mile and a half on concrete, especially if done every few days. As long as she's having fun and doing healthy things we'll support her the best we can. But as any parent with kids knows - next week I could ask if she wants to go run two miles with me and she'll shrug, roll her eyes and say "BOR-RING."
