Tomorrow is the Ironman Coeur d'Alene. Almost 2500 people will brave the cold water (16C) for 2.4 miles, then ride through hills for 112 miles, just so they can be sufficiently warmed up to run a marathon.
Shelley is competing in what will be number five or six for her. Crazy.
Ironman has a very cool system for race day. You can track athletes as they progress throughout the day. It's a very handy system, especially when it takes over 12+ hours for the 'average' person to finish.
