The Next Level Challenge - August 2010

It's that time again and I need to work on challenging myself physically this month.  Last month I threw down a challenge to complete a 4 mile hiking trail by my house and I was able to accomplish this task.  Below is one of the pictures I took on the hike.

There is a larger trail that I could challenge myself to completing, but I'm not sure if I want to do that or perhaps look in another area to challenge myself.  Perhaps a bike ride?  Perhaps a longer walk?  Perhaps something else new?

I don't have much time, so I'll look to decide on something this week.
