Day 3:

 Took a run last night with my 13yr old. We only went just shy of 3 miles, my quads were pretty sore from the previous 2 days, so we took it easy. Once warmed up I actually felt better than the day before though, and this morning my soreness is lessened. My son was more fit than me from a season of soccer playing, he said I was going SLOOOOOOOOOW. What a little jerk :-)

 Learning to swim tri-style...probably gonna be the hardest discipline to learn. Getting out of the water in a reasonable time seems a loooooooong ways away.

 Biking: most likely gonna be my easiest once I am getting fit. I have long, strong legs and these should suit me well for a bike ride of 6-7 hours. Not scary at all, just a loooooooong boring ride. Probably going to be very hot so this is going to set the tone for the run coming up afterwards, it will be incredibly important to hold back here.

 Running (or wallowing in a daze) the marathon: Going to be the hardest thing I have ever done in my life most likely. It seems impossible right now that my legs are going to be able to carry me 26.2 after the previouse bike ride!

 But to be sure, thousands and thousands have accomplished this before me, and I suspect I will find some inner strength along the way from family and friends.

 To infinity, and beyond!
