My employer sponsored a 5K today.
There were about 40 participants, and I finished second in my female age group. I was 10-ish seconds behind the top finisher in our female age group, who happens to be a good friend of mine.
I started out with a friend, that top finisher, who I knew would be faster. After roughly a half mile, I fell back a bit and ended up running with a new team members to our department. We hung together really well through it.
My first mile was at 8:44.
My second mile was 10:00.
My last 1.1 mile was 8:14.
And it was a personal record 5K time!
