I am right there with you.
I went on a trip to the UK in October 2008 to see Manchester United play. When I got back, I took a look at my pictures and was horrified by what I saw. But pictures don't lie. My godchild was born in November, and in December I decided I needed to change, a couple things.
On December 12th, I went into my 24 hour fitness, which I had been a member of for 5 months, but never used, and asked about a trainer, because I decided I needed to learn how to work out. The guy was great and we set up a meeting for the next week. He wanted me to figure out what I wanted and to set some goals.
December 19th started my journey. I was right about 240 when I stepped on that evil scale (been a LONG time before that since I had actually been on one of those). We talked and set up 3 goals that I wanted to use as points in my journey.
1...Run the Cirque de Solea 5k in March in Vegas.
2...Run the Pat Tillman run in Tempe in April.
3...Run the Disneyland Half Marathon in September.
I started with learning how to work out and how to use a treadmill. Then it went into "jogging" outside. A minute at a time to start. Then longer distance and repitions.
Each of the goals I set gave me that 'something' to shoot for and work towards. My first 5K was about 35 minutes and I was pushed by a little 10 year old kid that was "racing" me the whole way. HAHAHA I beat him. But more importantly I finished. Pat's Run was everything I imagined it would be, and by then I had so much fun running that I added a 5K happening in Tempe the next morning, and had my fastest run to that date.
Finally. Running through the Vegas summer, getting up at 5am to run before the heat hit, getting to the parks late on my trips to Disneyland because I had to get my runs in...they were all just little things towards that final goal. I ran the katella, harbor, disneyway, loop around the parks on one of my runs and it was amazing to thing that I would be running 13 miles soon. When a year ago, I would have had issues running 1 block.
Use the run as your goal and inspiration. You will be with 10,000 other runners who love the mouse. I ran with a pace group (highly suggested) and one of the ladies was dressed as Tigger and she would "bounce" when people yelled out at her. The 13 miles went by so smoothly and quickly. Enjoy the training. Take the good runs with the bad runs and remember that you are changing your life for the better. Running through the parks with the characters cheering you on is one of those experience you will talk about forever.
I just ran my 2nd half marathon here in Vegas today and am running a full in January at Walt Disney World. I run 10-11 minute miles and will never be an elite runner. I go to kick boxing classes twice a week. I have lost over 50 pounds now. I have gotten my life back and know I have a chance to spend more time with the people I love. And I can not wait to get back there and do my 2nd Disneyland Half this coming year!
You can do it!
Have FUN!!!!!!!!!!
