Entries are accepted on a first-come,

first-served basis from 8:00 pm on 30 October 2026 until 11:59 pm on 31 January 2027, and entries close early once the field is full.

One of the registration sites in Japan was suspended because of a fault, and a second round of registration is being prepared.

Runners residing overseas pay a fee about ¥3,000 higher than the rate for residents of Japan,

and register on an English-language registration site for overseas residents only.

The FUJI100K RECORD CHALLENGE requires you to submit a qualifying result.

Elite runners need a 100 km finish within 7 hours 30 minutes (men) or 9 hours (women) since January 2025;

general entrants need a finish within 4 hours 30 minutes in a full marathon or within 12 hours for 100 km.

Runners aged 25 or under (U25) register at a discount of about 20% from a separate quota.

The 100 km U25 quota is 90 runners.
