I am a long distance runner turned triathlete. I was training for an Ironman distance triathlon. This includes a 2.4 mile swim, 112 mile bike ride, and a 26.2 marathon to top it all off. During one of my long runs, I had a problem with my shoe lace. I took off my bracelet to use the paracore, and my lace problem was a memory! I hated to waste my bracelet, but sometimes you gotta do what you gotta do! This is no big hairy story, however, the bracelet got me through an important run. Much Thanks!!! I had only had my bracelet 1 week, and I plan on buying another. I know you will replace it, but I am really thankful and will be buying a new one. That's just me!!!
