FireSprite... I actually prefer to walk! Shhhhh... don't tell! But DD10 has become quite a little runner and I figure it might be good for me to be able to keep up (and I do really enjoy running too to be fair!)
I think that it's great for our kids as they're able to get a bit more independence and especially for US as we can get some time for ourselves...
My kids are with my 24:7 essentially so we all need a break from one another now and then!
Good for you for getting out there and doing stuff for yourself too!
