I really like the idea Hitsua is trying to get going here (ie sort of everyone posting on a daily basis how much they ran). Unfortunately where I live there's really not a whole lot of good places to walk or jog. I've had a personal training contract for a year or two now but I'm really on and off with it (I last worked out with my trainer in feb/march, even though I have to keep paying for it). I'm going to have to start using that again soon.
However, I'm all for participating in this, and I will participate (although it may not be a huge length I run or jog every day). I'm also all for giving rewards to people that do participate (i.e premium user, or anything else I can think of).
Great idea Hitsua.
