• About the event:The Western States ® 100-Mile Endurance Run is the world’s oldest 100 mile trail race. The Run starts in Olympic Valley, California, near the site of the 1960 Winter Olympics, and ends 100.2 miles later in Auburn, California. In the decades since its inception in 1974, Western States has come to represent one of the ultimate endurance tests in the world.
  
  Traversing the traditional lands of the Nisenan, Washoe, and other neighboring Indigenous Peoples, the Western States Trail climbs more than 18,000 feet and descends nearly 23,000 feet before runners reach the finish at Placer High School in Auburn. In the miles between Olympic Valley and Auburn, runners experience the majestic high country of Emigrant Pass and the Granite Chief Wilderness, the crucible of the canyons of the California gold country, a memorable crossing of the ice cold waters of the Middle Fork of the American River, and finally the historic reddish brown trails that led many travelers, including gold prospectors, to Auburn.
  
  For five decades, Western States has been home to some of the sport’s most stirring and legendary competitions. With more than 1,500 dedicated volunteers helping to create a once-in-a-lifetime experience, the Run has stirred the spirit of runners from all walks of life, from all over the globe.
  
  Offering the sport’s oldest and most prized possession – a sub-24-hour silver belt buckle and a sub-30-hour bronze belt buckle – Western States remains one of the undisputed crown jewels of human endurance.
• Aid stations:Perhaps the one thing that stands out most in the memories of every runner who participates in the Western States Endurance Run is the incredible volunteers who work the aid stations. With a staff of over 1,500 volunteers, the support given to the runners is unparalleled. The river crossing alone has a team of 125 personnel. There are 20 aid stations, including 10 major medical checkpoints along the course.
  
  The aid station captains have many years of service at Western States and are professionals. The aid stations are well stocked with fluids and a variety of foods. The fluids that are generally available are: water, GU Hydration Drink Tabs and ROCTANE Energy Drink, Sprite® or 7Up® and Coke®. The night aid stations will also have soup, hot coffee and hot chocolate. The foods that are generally available are: salt replacement foods (saltines, pretzels, chips), GU ROCTANE Energy Gels, GU Liquid Energy Gels, fruits (oranges, bananas, melons), potatoes, cookies, candies, sandwiches, etc. Hot soup will be available at several of the aid stations, including the River Crossing, Auburn Lake Trails and Pointed Rocks.
  
  Western States is a cupless race. GU will supply reusable HydraPak SpeedCups and HydraPak 5-serving gel flasks to athletes.
  
  The use of Ibuprofen (Advil, Motrin) or Naprosyn can lead to kidney problems when used in abundance and/or under stressful conditions such as running a 100 mile run. We will not provide these medications at our aid stations. If you feel the need to bring and use your own pain medications or anti-inflammatories, then you are willing to assume the responsibility for their use.
  
  Our medical staff also has many years of service at Western States. With a staff of approximately 50 physicians, 75 nurses, podiatrists, emergency medical technicians, paramedics and massage therapists, we try to provide the safest and best medical backup available. Some of these people have been participants in the Run, making them all the more aware of the needs of the runners.
  
  Without the assistance of these 1,500 invaluable volunteers, there would be no Western States Endurance Run. Many of these volunteers have spent days preparing for the Run and will be at their stations for over 30 hours. They have given up their day to insure you the best possible chance of success. They have given up their weekend to insure you the best possible chance of success. Giving each volunteer the courtesy, respect and sincere thanks that they each richly deserve is all that we ask.
