In the past 11 months I have run a few 5ks, a 15k and a 10k. I have run in 35 degrees and 100 degrees. I am currently training for a half marathon. I used to bring my running shoes and shorts on vacations on the off chance I would find time to run. This time I am determined to run - I have registered for a 10k 3 days after We return to keep me on track.
Other exercises are much easier - sign up for classes and follow the teachers' direction, join a gym and use the bikes or elliptical machines. I don't want to belittle those who choose other forms of exercise, I've done all those and you will burn calories and feel better about yourself, but I know I feel much better after a run than after a class or a session at the gym. A good run proves that I had the motivation and dedication to go for a run just because I wanted to, not because someone else told me to, or because I signed up for a class and don't want to waste the money. I used to see people running in bad or cold weather and think they were crazy, now I'm jealous I don't have the same motivation.
I am a runner.
