ひたちシーサイドマラソン

How to enter

Online entry via RUNNET (Japanese platform) or Run Japan (English-friendly platform for international runners).

Entry platform

RUNNET (Japanese) and Run Japan (English option available for overseas runners).

What you need

Runners must be 18 or older as of April 1, 2026, and able to finish within 6 hours. Registration on RUNNET or Run Japan is required.

Payment

Entry fee is ¥10,000 plus a handling fee (¥240 for fees up to ¥4,000; 6% for fees over ¥4,001). Payment options include credit card, convenience store, and ATM.

Bib pickup

No race-day reception. Bibs, timing chips, and parking permits are mailed to participants in late October. Overseas runners should ensure they have a valid Japanese mailing address.

Entry period

General entry: April 13 – August 31, 2026. Run Japan entry: same window (April 13 – August 31, 2026).

On race day

No on-site bib pickup; all materials are pre-mailed. Aid stations are provided on course; personal drinks are not accepted.

Notes

Run Japan provides an English-language entry path, which may be more accessible for overseas runners. Bibs are posted by mail, so overseas entrants need a Japanese address for delivery. No mention of overseas-specific restrictions, but Japanese infrastructure for payments and mailing may pose practical hurdles.
