The wildebeests of Tanzania and Kenya embark on a yearly trip of around 1800 miles - the great migration. Baby wildebeests are able to stand and run within minutes of birth. Wildebeests are active both day and night. Although they can reach a top speed of around 40-50 mph - hardly the fastest animals on the plains - wildebeests are best known for being relentless in their advance.

I am busy making final preparations for my race this weekend: the Potawatomi 100 Mile Run in my hometown of Pekin, IL. I'm organizing my supplies and extra gear. The training is done, this is all that's left to do. I don't know if my training has been adequate. I've trained seriously, but I never know if it's enough. I'll find out on Saturday into Sunday.

The race begins Saturday at 6am. The cutoff for finishing is 4pm on Sunday. 34 hours. To run 100 miles.

In the last few days and weeks I have been peppered with questions about why. I don't know. I know it has something to do with cancer. It has something to do with the fact that maybe I can. But I don't really have an answer. Maybe I'll figure out the answer by the end of the race; I'll have a lot of time to think about it.
