My first 5K, Race for the Cure Seattle. My HOPE was for a sub 30 minute performance. I got a 29:33 and wanted to stop the ENTIRE TIME. I could have given up there and thought "I can't run fast or for long distances!" But I didn't!! 2 years later I qualified for the Boston Marathon.
Do you have a Goal? Something that you have ached for but don't believe you can do? My advice START NOW!!! Don't wait! Life passes too quickly and you don't want to sit in your rocking chair and wonder what might have been.
