Outdated Half Marathon PR

I have the green light from coach to race the Chicago Half Marathon at the end of September. This is exciting. But the only question is, how do I race it? My official half marathon PR is a bit outdated. But my current pace card dictating a 6:35/mi pace seems a bit aggressive. Or is it?

Thanks for watching! Leave a comment to let me know you stopped by!

The charity runner of the week is Emily McCool, who is running the New York Marathon and raising money for Brain Injury Association of New York State. I've donated $70 to her fundraising efforts and hope you'll consider joining me.
