Ok wanted to post my "starting point weight" and where I am at now. I started my recent changes in lifestyle (deliberatly avoiding the "DIEt" word) about 3 month ago. At that point I weighed in at a hefty 315. My current weigh is 280 for a weightloss of 35 pounds.

The good part is my employer has a health club on site that has a full set of weight machines as well as cardio equiptment. I have been going to the gym for like 2 hours during the 4 days a week I work. I typically do either upper or lower body circuit for a couple sets each and then do at least 45 mins on the treadmill. Currently I get the treadmill fired up at around 3.7mph and then gradually work it up to around 4.7 for the majority of my time.

Just got a key to my apartment community health club. It's a bit more people using it and is usually a bit more crowded, the good part about that is unlike the work one I can drag my wife with me!

Goal:
I would like to gradually work up my endurance level in cardio to be able to WALK a marathon 26.2 miles. That is a bit off, right now if I hit the outdoor trail I can usually walk around 12-13 miles, but I think I end up getting bored more than tired and with me driving down to the trail I know I have to walk back to my car to get home so I usually try an estimate on the safe side.
