Content Creator & Running Coach
Colorado Springs, CODo hard things!
I’m a running and strength coach who believes great performance is built on durability, consistency, and science-backed training; not hype or guesswork. Alongside coaching, I run my YouTube channel, UltraTrailSteven, where I extensively test and review running shoes, gear, and technology in real-world conditions, giving me a practical, hands-on understanding of what actually works for athletes. With a deep background in trail and ultra running, strength development, and injury prevention, I help runners train smarter, stay healthy, and make informed decisions about both their training and their gear. Every plan I build is personalized, intentional, and rooted in proven principles, so you can build strength, confidence, and long-term resilience without burning out or breaking down.

Steven Kornhaus's Expert Gear Recommendations
No Business 100
This is my curated list of gear I believe is perfectly suited for the No Business 100 course and weather!
- Apex 4 by Coros — I think The APEX 4 is definitely the best watch in COROS’s lineup currently! The new and much faster processor, maps with street names and POI’s, sapphire glass and incredible battery life, this really is the ultimate mountain sports watch!<div><br></div><div>The APEX4 has great maps, and you can load the No Business 100 GPX file and see the distance to the next aid station. Plenty of battery life for the race!</div>
- Prodigio Pro by La Sportiva — The bottom line of the La Sportiva Prodigio Pro, is these are fantastic shoes for long days on the trails. Whether that's a long training run in the mountains of Colorado, or crushing some beastcoast vert at Frozen Head State Park, the super comfortable upper, the responsive and energetic midsole, and impressively grippy outsole really do make the Prodigio Pro the perfect 100 mile shoe in my opinion.
