If you are reading this on Sunday morning, anytime between 8 am – 12pm Eastern Time, or 6 am – 10 am Mountain Time (the time zone that I’m in), then I am currently running the first marathon I’ve ever run in my life. Last year, I ran the half-marathon version of this same race, and it was the first running race I’d ever been in. (The picture above is not me, and it’s from last year, but this is the finish line of the Missoula Marathon.)

I decided last year to get in the best shape I’ve ever been in by the time I turned 40, and running seemed like a good way to do it. I have since run two 5Ks and another 1/2 marathon last winter. But today will be my longest run ever.

Of course I am doing it for myself, but I am also doing it for my family, because running makes me healthier and happier, gives me more energy and sets a good example for my two sons, ages 4 and 6. And I am also doing it as part of my fundraising efforts for the Cystic Fibrosis Foundation because my youngest son has Cystic Fibrosis. I have been documenting my progress for the last year or so on my blog.

I think it is really amazing and wonderful that I’ve lived in this body for 40 years now and I’m still learning what it can do.
