Good thoughts. You're in a good place and very well grounded. Separation and divorce can be devastating and the point is to shake things up and take charge of your awesome life. A 5K would be super great! Oftentimes the 5K's will have a 1 mile fun run that you could train for and do with your boys.
You do a lot that revolves around the kids and clearly love it. I can completely relate. I immersed myself in my boys and was a PTO volunteer, cub scout leader, active in playgroups, and part stayhome mom with a houseful of craft and educational projects.
Are you keeping up with the woman side of you as much as the mom side? The you that was you before you were a mom? (I think that is why I liked the 5K idea, but then I turned it back into a kid-oriented activity with my idea).
