About Me

John Vonhof brings a varied background and extensive experience to Fixing Your Feet. This book, which he wrote and illustrated, is the synthesis of over 18 years of experience as a runner and hiker. John is pictured here with Denise Jones, the Blister Queen of the Death Valley Badwater Ultramarathon.

Having run since 1982, John discovered the challenging world of trail running and ultras in 1984. Over the years, he has completed more than 20 ultras: 50KMs, 50-milers, 100-milers, 24-hour runs, and a 72-hour run. John has completed the difficult Western States 100  Mile Endurance Run three times and the Santa Rosa 24-Hour Track Run ten times.

In 1987 John, with fellow runner Will Uher, fastpacked the 211-mile John Muir Trail in the California High Sierra's in 8.5 days with 30 pound packs.

As the former race director of the Ohlone Wilderness 50 KM Trail Run (15 years), John worked at providing a quality event for runners of all skill levels. This run is known as one of the most difficult 50 KM trail ultras in Northern California.

An opportunity to change careers in 1992 led him into the medical field where he has worked as an emergency room technician with certifications as a paramedic and orthopaedic technician. He currently works for the Alameda County Emergency Medical Services Agency in the San Francisco Bay Area in Central California.

Over the years he has provided volunteer medical aid at numerous running events and has patched thousands of feet at events like the Western States 100 Mile Endurance Run, the TransRockies Race, the Raid the North Extreme Adventure Race in northern BC Canada, the Primal Quest Expedition Adventure Race, the Atacama Footrace in Chile, the Coastal Challenge in Costa Rica, the Avon Walk, and more.

This background has provided a wealth of learning opportunities for what can go wrong with feet and ways to fix them.
