Linda,
It's all about the attitude... and it sounds like you've got it! Of course, everyone needs a little encouragement every once in a while. A friend of mine who, like you, started from the couch just a about a year ago, has now completed two half-marathons. She is not fast, just persistent. She recently signed up for a 10K that my wife and I were going to do with her. As the date of the race approached, she received a call from someone from the race asking if the expected finish time that she put on her registration was a "mistake". It was not a mistake. The race representative then informed her that, unfortunately, they did not have a walking permit from the local police department for the 10K and asked her to change her registration to the 5K, for which they had a walking permit. She then informed the representative that, in fact, she had not intended to do any walking! Well, she ended up in the 5K anyway and she was not super happy about it. However, she has a great attitude and decided not to let it bother her.
At the end of the race, we met her at the finish line and she had a somewhat disappointed look on her face. We knew that she had come in a little quicker than her goal time, so we were confused as to why she looked so down. We finally asked her and she responded, "I kept getting passed by a 90 year old man. I'd speed up to pass him, but then in just a little while here he'd come again!" I told her not to worry about it and said that he has probably been running for 40 years. There was no need to be ashamed. She said, "It's not that he was old. I've been passed by older people before. What's humiliating is that he was carrying a cane!" Once she started laughing, we all realized that she hadn't been disappointed at all, but was setting us up for the story, which, by the way, was true.
This event just added to her collection of running adventures that she loves to share with anyone who will listen. Incidentally, this race was also her husband's first race. Her perserverance and positive attitude inspired him to get up off the couch and get moving as well.
