You versus you and the Mountain…

The IronHike Endurance Series is part of a new classification of events that combines physical, mental, and spiritual gumption. These are NOT races. No Podium, no age group awards, and no records to break. These challenges will change your life! Extraordinary Events for a broad range of fitness and skill levels, from ordinary people to seasoned and elite Mountain Athletes reaching beyond their comfort zones!

Invest in yourself…

Change your story.  Do something hard, either for the first time ever or again! This is about you and the mettle in your own heart. It is about your journey toward becoming the best version of yourself.  Each summit takes you closer to overcoming the super-hard and allows you to let this epic experience change you for the better.

What you’ll do…

Hike it, run it, alone or together, or in our unique FlexRelay format with your trail buddy or your team of 4.

Rest when you need to. You will summit and descend the same mountain until reaching the equivalent elevation of the namesake mountain of your event. This is your extreme mountain long haul to manage and conquer!
