Ed,

I think you will find many different opinions regarding treadmills.  While they may be a necessary evil for some, others (and I include myself in this group) would rather run through a blizzard.  I've always found that treadmills supress your natural running stride, so that once you get out in the road and open your stride up a bit, you tired more easily.

Keep in mind that your brain to some degree is dictating your natural running pace, and it will take a conscious effort on your part to slow things down, at least at first.  If you lose focus, you can end up accelerateing and tiring yourself out.  We all have discouraging days, but you will have far fewer if you can avoid burning yourself out.  Good luck, and hang in there!

Gosh I remember feeling the same way when I moved from TM to outside! I had gotten pretty good on the TM, but running outside made me feel like I was starting all over (or at least taking some steps back!) But definitely don't give up... it does get easier and you will see results and improvement as long as you stick with it. If you don't have a HRM I definitely suggest investing in one... if only for being able to pace yourself and slow down if you find your heart rate too high. I know as a runner when I build up to something new (like a longer distance or an unknown course) I will tire myself out quickly from going to fast...sometimes slowing down is as simple as just reminding yourself to take it easy. Good luck ed!!!

I never run on a TM (although I use an ellipitcal sometimes) but from what I understand you need to set your TM incline at 1-2% for the resistance to be more like running outside.  If you have no incline the TM may be too "easy" and then running outside will seem harder.

If you are new to running don't worry about trying to keep up a particular pace.  You have time to work on speed later.  For now, run at a comfortable pace for MOST of your run with a few intervals of higher intensity to help increase your conditioning.  The intervals can be a minute or two of increased speed or running up a hill.  If you aren't comfortable doing the intervals yet, then just concentrate on keeping a pace that is steady and slow enough that you can run for at least 20-30 minutes at a time.  When that becomes comfortable to you, then add in the intervals.  Meanwhile, ramp up your TM so you get a better workout and don't stress too much about the speed for now.

I know its easy to say, but don't get too discouraged.  Running isn't easy and it takes time and effort to reach your goals but the rewards are well worth it.

Running outside is definately different than running on the treadmill.  I actually run slower outside than I do on the treadmill, but that could also mean that I'm going a longer distance typically.  Just go out there and have fun.  Don't get discouraged, just remember that every surface is different, and will alter your running speed and pace. For instance, running on the treadmill might be faster than pavement, and running on pavement might be faster than running on sand.  Each surface has a purpose in your training, the important thing is to go out and have fun and enjoy your workouts.
