When you register for the 2017 Washington Ironman Championships Naturally, we send you a silicone accountability wristband that says 2017 Washington Ironman Competitor on it. It is incentive to keep you on track for the show with your preparations. Every time you open the fridge to cheat or decide to skip a workout, you will see your wristband to remind you of your goal. It will also help you recognize other athletes getting ready for the 2017 Washington Ironman Championships Naturally. Plus it glows in the dark! Hold it up to a LED light for 1 minute. We have found it holds a charge for about 8 hours.
