I run at least 2 miles a day most of the time, sometimes I skip the runs and just take the dog for an extreamly long walk, but rather do the running. I don't usually use weights but I do look for the biggest hill I can find to run up.
I run 4 or 5 times a week, a couple easy 5 milers, a 3x2 mile at 10K pace with 2 miles warm up/cool down (8 miles total), sometimes 200m or 400m intervals and a 14 mile long run. Since May 2008, I've ran 3500 miles, I don't have stats from before then. I started running in 2006 and I go to as many local races as I can. Addicted to it, I am.
Used to be right into it... but not so much nowadays. Still keep fit, just not via running. I do plan to get back into again in our next place, as it comes with a full private gym in the building as part of our body corporate... so I will be getting back into running, but on the machines... not so harsh on the knee's then, being pretty much why I stopped on road, as years in the military are not so kind to the knee's. Now I only run on running machines. I want to get back to around 30 - 40km a week once moved. I found running is just the best for overall fitness and physique.
I usually run in a state park around here, going on the bike trails and some of them are quite steep/rough but it's really fun. I've started to do 5k runs and will probably work higher as time goes on.
