Water temperature could be between 65 to 68 degrees, so a wetsuit is allowed recommended but not required. If you have a wetsuit, I recommend you wear it as the wetsuit not only keeps you warmer both in the water and while waiting on the beach, but the wetsuit also increses your buoyancy. Unfortunately you may have trouble finding one, especially us Wyoming residents, so I recommend getting yours now as you won't find a triathlon wetsuit offered by any of the Cheyenne merchants. Wetsuit should cover your shoulders and neck to prevent the wetsuit from catching water like a sail, yet loose enough in your shoulders to allow comfortable arm movement. Try Sierra Trading Post, or Runners Roost in Co. One of the race sponsors, Rock on Wheels, here in Cheyenne, also rents out some great triathlon bikes and Rock on Wheels will also have some wetsuits to rent this year as well. Contact the store at 307-637-0020. Don't worry if you don't have a tri bike, because road bikes and mountain bikes are allowable. But no IPods, walkmans, etc are allowed on any portion of the course. That's a USAT rule!!
Note that bicycle helmets are required. Bicycle helmets must be undamaged and unaltered, and must meet or exceed the safety standards of the Consumer Product Safety Commission (CPSC). Helmets manufactured prior to March 10, 1999 must meet or exceed the safety standards of the American National Standard Institute (ANSI Z-90.4) or the Snell Memorial Foundation. Please see www.usatriathlon.org for a complete list of all triathlon rules.
Make sure you have a water bottle on your bike, as there are no aid stations on the bike course. Splash pools will be set up along the transition area to rinse your feet after you before entering the transition area. Rock on Wheels will be on hand race day to provide minor adjustments!
Please note that only athletes will be allowed to remove their belongings from the transition area after the race. Volunteers will be posted in the transition area and you will be required to show your bike frame matches your body number. No relatives or friends will be allowed to retrieve equipment in the transition area.
