I signed up for a half marathon in 6 months, along with 3 aunts, 2 uncles, and several cousins and siblings. I am a little surprised this became as much as it has for the family, but it's the first time for me and several others.
I'm not too scared about the training, I was running regularly in the spring without trouble (2 or 4 miles), but if there is anyone likely to have imbalances or tightness from sitting too much it's me. I am going to try the exercises from the thread last week.
We've also visited my parents, in-laws, my grandma, and her grandparents in the last week, so I'm ready for some quiet time.
