Back in mid-November I did the Lightfest 8k. This wasn't *really* a race since it wasn't timed and also the course was longer than 8k, which I'll get to in a second. Additionally, we had trouble finding the right place to park so we were late to the start and didn't warm up.
Despite all that I decided to run fastish and see what I could do. The first 4 miles were Between 6:05 and 6:20 but I missed most of the mile markers so I don't know exactly what they were. I was okay with this - I just enjoyed the course (it was fantastic to see the light displays) and also kind of had fun weaving through people playing catchup to the runners.
My last mile (yes, full mile. In an 8k.) was 5:10. It turned out that after 4 miles I was warmed up and realized that if I ran fast I could PR my 8k despite all the setbacks I mentioned above. It turns out the course passed the 8k mark, had a 5 mile mark, and then finished just past there. Based on extrapolation for 5mile->8k time I put myself at 30:15 which is a 50 second PR in my 8k! Win!
