Izu Trail Journey is an international trail running race spanning the Izu Peninsula from Matsuzaki Port to Shuzenji Hot Spring, featuring a grueling 70km course with breathtaking coastal and mountain views.

What this race demands

This 69.1 km trail running race requires sustaining forward motion across 3,242 meters of climbing over a demanding December duration.

Climbing volume

Accumulating 3,242 meters of elevation gain over a 69.1 km distance requires consistent uphill pacing and muscular endurance to manage sustained ascents.

Distance durability

Covering nearly 70 kilometers on trail terrain demands robust physical and structural resilience to withstand hours of continuous impact.

December timing

Racing in December necessitates adequate cold-weather management and appropriate layering to maintain thermal regulation throughout the long effort.

Given the prolonged duration well exceeding 2.5 hours, athletes should aim for an intake of 60 to 90 grams of carbohydrates per hour to maintain energy output.
