Walking vs Running

I am torn!   Last year I ended up walking over 400 miles (check out my sidebar for 2007 totals).  The highlight was in December, when I walked the Las Vegas Half Marathon.  I ended up walking it in 3:04 (for 13.1 miles).  It averages to a 14:03 pace per mile – which is really smoking for a walker.

 For 2008, I want to increase my intensity.  My problem is this.  I really like walking, and I never have to worry about getting injured.  But it doesn’t raise my heart rate high enough anymore.  So I’m thinking of running, but I’m worried I won’t like it as much, or that I’ll get injured.  Last year I started running, but somehow messed up my calf, so I had to give it up.

So far I have not ran this year.  I have walked more uphill, and walked on treadmills at an incline.  I’m not sure what I’ll end up doing.  I guess we’ll see. 

Either way, I know I’ll keep tracking my stuff at Sweat365 – it’s what keeps me going.  I love seeing the miles and the hours build up.
