Not running Wisconsin

I am scheduled to run the Wisconsin North Face marathon as my training run this Saturday. That's not going to happen due to a personal tragedy. The director of our research group and my academic father-figure passed away on 14th evening. He was a holocaust survivor, a giant in my field, and a personal hero. With the funeral service on Friday afternoon, there is no way I can make it on time. This would be my first DNS. Here's to you, Fred.
