Besides being an avid runner. For the past year and half I have discovered and indulged myself in the sport of Ultimate Frisbee. At first I was very skeptical because usually when people think of frisbee usually they think of casually passing the frisbee back and forth in the sunshine on a beach somewhere.
Well "Ultimate" Frisbee is quite the opposite of this in fact. You do loads of running up and down a huge field chasing a flying disc and also chasing people who are chasing the flying disc to block it down. I would describe it almost like soccer but with a frisbee. A lot of stop and go running and a lot of sprinting.
For the most part i've always been a long distance runner not really working on my short runs and sprints as I should be. I have found though that Ultimate Frisbee has been a great fun way of working more on my sprinting and short run bursts.
So over time friends of all athletic types have come and out and joined the team. I have found that no matter your work out style or body type--this is a great alternative cardio sport for sure. You'll find yourself getting into shape and having fun at the same time. For me personally it is a good break during the week from my regular training runs.
So my advice--mix it up! Try different activities and sports besides the one that you are most passionate about. It can't hurt right! Get out and be active.

I really like this quote, very short and simple but yet so powerful and true.
"Desire is the most important factor in the success of any athlete."
Willie Shoemaker

Desire is key in my opinion in any sport. Especially in running because like in any high endurance sport it takes a lot of desire and will to follow through. I feel that no matter the outcome of your race, your event or your training that you should always keep your desire for it strong. Never lose sight of that. You will always be a better athlete and person because of it. Desire builds will and dedication. The more you stay dedicated the stronger the desire inside you grows. They'll be times you'll hit that wall and you want to give up. It is so much easier to give up but if you dig deep enough that feeling goes away. The desire comes through and suddenly you have a burst of energy to break down that wall. It is then that you realize that your hard work and training are paying off. Each time you break down those walls, your desire, will and dedication grows stronger. Every athlete must break down barriers and walls to get better, as such in life. So when people ask why you run so much or say that you are crazy for it. Just remember inside you are working for something much deeper than a workout. To me this is what is desire and dedication are all about.
