Who is USA Ultra Triathlon™?

USA Ultra Triathlon™, also synonymous with Anvil, is an organization dedicated to offering a challenging and rewarding ultra triathlon experience – beyond the traditional ironman-distance. It’s for those who have conquered the mountain peak of an extreme competition (100 mile runs – Ironman triathlons – Adventure Races) and were left wondering…

is there a bigger mountain…?

With three unique venues each year, we provide athletes looking to push themselves farther, faster, longer, a chance to find out what they’re really made of! Up to five and a half days of intense, soul defining endurance performances competed by some of the world’s most hardcore triathletes. Not for the faint of heart, Anvil was created for those who just can’t quit.

You Only Accept 50 Athletes Per Venue? Why so exclusive?

That’s a good question, and it’s something we take extremely seriously. Competing at the level of these ultra distances take a much bigger tole on athletes than a traditional triathlon, which requires a level of attention on our part that becomes unsustainable without a limited number of participants. Our number one priority is the safety of our team, and that’s not just limited to the physical, but the mental, emotional and spiritual safety as well. In fact it’s exactly this reason that people come to compete with us year after year after year. It’s what makes us different.

With us, you’re not just a number on a score sheet. In fact, the most popular word used to describe our organization is “family”. Keeping our numbers down is in our athlete’s best interest, it allows us to give them everything they need in order to succeed in pushing themselves as far and as hard as they can possibly go, and that’s exactly what we’re all about.
