In an effort to be more sustainable and friendly towards the environment, the Ironstone 100K Ultramarathon is a cupless races. All runners will need to carry their own reusable cup throughout the race to use at aid stations.

The use of Ibuprofen or Naprosyn can lead to kidney problems when used in abundance and/or under stressful conditions. Aid stations will not provide these medications to any runner. 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.

The aid stations are well stocked with fluids and a variety of foods. The fluids that are generally available are: water, hydration/energy drink, ginger ale and cola. The late stage aid stations will also generally have soup and hot coffee. The foods that are generally available are: salt replacement foods such as saltines, pretzels, chips; fruits such as oranges, bananas, and melons; potatoes, cookies, candies, sandwiches, etc. Aid stations also try to have their own unique foods available throughout the course. Generally vegetarian options are available but we cannot guarantee the ability to accommodate all dietary choices and restrictions
