Circuit
I have the older (green) model and the pack is great. I have just used it on a four day backpacking trip through Haleakala and even though I am only fourteen, this pack allowed me to carry fifty pounds worth of gear comfortably. It fit everything; sleeping bag, tons of food, water, 2 man tent. The only problem I had with this pack was that it is very hard to reach the water bottle pocket while wearing it.

One of the most comfortable packs I've tested.
This is a great pack, there's one word for it: great.

Training Tips

Low weight, high rep circuit training combines the best of both worlds: aerobic and anaerobic training. Keeping the rest time in between high repeats low excercises like bench press, leg presses, inclined sit-ups, and upright rows is the key to maximum benefits.

As a long distance runner, a gradual increase in distance each week will allow you to build a solid areobic base. Distance increase should be no more than 10% of the previous week's distance.

When buying a new pair of running shoes, bring your old ones with you. You will get a better fit if you know if you supinate or pronate.

Heart monitors are useful for knowing when you are in the right zone for your training efforts. If you understand what your maximum heart rate is, you can set up your monitor to beep at you when you exceed the high or low range of your heart rate for the type of workout you are doing.
