Racing this weekend

The Canberra Challenge is this weekend and it's my first Olympic Distance tri (1500m swim/40K bike/10K run). I"m excited and more than a little nervous for the pain. I know I can do the race, but it's going to be a long time out there, cause I'm just not as fit as I should be. Ha. Like anyone ever really is for something like this. Especially after a month at home with family and Mexican food. Doh!
