My DH told me about his days as a ski-instructor before we met, but was not too athletic for a long time. I was slightly more active as a field biologist and birder- but not really athletic at all.

Sometime after he recovered from cancer, he began to to talk about bike commuting to work. Much to my surprise, he stuck with it. Then he began to have a goal- to complete a 50 mile run by his 50th birthday. He again surprised me by following a rigorous training program, running a half-marathon in 6 weeks and a full marathon 5 months after starting. Oh yeah, and he's done a 50+ mile run for his birthday for the last 6 years, plus more marathons and 50 milers as well.

I didn't catch on for a long time- but 2 years ago decided I had to do something to lose weight, and got back on a bike.

He is much stronger than I am but is willing to slow down for me if we ride together (I just can't run!) It has rekindled our relationship in many ways to share this time together- I hope we don't decrepitate too soon and lose our ability to enjoy this as we cruise through on through our 50's and beyond.
