TRAILFEST ENDURANCE SERIES
25K / 50K / 100K / 120K / FAMILY 2.6K.
Go beyond yourself this winter, in the ancient land of Asuka, Nara.
From the one-lap 25K, to the 100K that runs through the night,
to the non-marked, self-navigated 120K.
There is also a 2.6K family race for children up to 12 years old (6th grade).
NO MARKING
40 km × 3 laps / experienced runners only
The top category: no course markings, you navigate on your own using GPX data. Not only running ability, but navigation, gear, nutrition and judgment are all put to the test.
ENDURANCE
25 km × 4 laps / through the night
Lap after lap of the same 25 km, through the night to the finish. It tests your ability to keep resetting your pace, nutrition, gear and mindset.
CHALLENGE
25 km × 2 laps / toward the next distance
On the first lap you learn the course; on the second, you learn about yourself. A 50 km step up to long trails that tests both your running and your self-management.
ONE LAP
25 km × 1 lap / focus on one lap
One full lap of the 25 km Ishibutai course. With climbs, descents and unpaved paths, it offers a rich trail experience quite different from road running.
FAMILY
Family race / 2.6 km
Children can run alone, or one child with one parent. A 2.6 km race to support children who want to run, and for families to enjoy the race-day atmosphere together.
Ishibutai 100 is a trail running race set against the history and mountain terrain of Asuka, Nara. The start and finish are at "Asuka Kaze Butai". Choose the distance that suits you, and make your way through Asuka in winter on your own feet.
Because it is a loop course, the same climbs and descents show a different face depending on the time of day and your fatigue. From the one-lap 25K, to the 100K through the night, to the 120K where you find your own way. The longer the distance, the more gear, nutrition, judgment and mental control matter, in addition to running ability.
Coming back on your own feet, all the way to the end. The preparation for that is part of Ishibutai 100, too.
