Actually, I often think that's harder when you have two serious athletes and kids. I divorced and remarried long ago when I was a runner. At the time I thought if I ever remarried it would have to be to some fit runner lady. Then I met someone who was my complete opposite but complemented me in practically everyway. My wife is overweight (and was when I met her) and her hobbies are nothing more exciting than reading and cooking. She is my best friend and I wouldn't trade her for anyone. She supported my running then and my switch to triathlons 7 years ago. Whatever race I want to do she is 100% behind me. She is as much a fixture at the LBS as I am. We'll be celebrating our 19th wedding anniversary this summer.
