Jember Trail Run 2026

Jember Trail Run 2026 brings a 10 km trail-running challenge to the Kalijompo area of Sukorambi, Jember, East Java, on Sunday 20 December 2026. The organiser positions it as an introduction to trail racing for newcomers and a chance to experience Jember's hilly, natural surroundings. Its published start is 05:30 WIB (UTC+7), with the event base at Area Lapangan Kalijompo.

Terrain and preparation

The organiser describes the trail as medium difficulty, with varying terrain and elevation. However, the official course-page placeholders still show no confirmed GPX route, total ascent or elevation profile. Do not rely on an assumed route, aid-station spacing or finishing time until the organiser publishes the completed course guide.

All participants are required by the current race regulations to carry:

• A hydration pack containing at least 500 mL of water
• Trail-running shoes
• A whistle

The organiser specifies no formal minimum age, but runners must be medically fit and physically capable of completing the event. Participants should assess their trail-running experience realistically and disclose relevant medical needs through the registration form.

Registration and race-day arrangements

The current organiser website lists IDR 190,000 per participant (with a possible processing charge). Registration opened on 10 September 2026 and the website continues to advertise registration; a definitive closing date or confirmation that places remain cannot yet be independently verified.

The registration process collects identification, emergency contact information, a jersey size and medical details. The organiser describes QRIS-only payment, followed by manual review and an email confirmation. Entrants should keep their confirmation and check their inbox for bib-collection instructions. The organiser's registration-flow text also mentions a '10K City Run' option, but the main event information confirms only the 10K Trail Run; this listing does not assume an additional race category until clarified by the organiser.

Participant arrangements

The published inclusions are a personalised race bib with timing chip, technical jersey, finisher medal, on-course medical support, hydration stations and refreshments or recovery snacks. Exact race-pack collection dates, location, course cut-offs, awards and cancellation/postponement rules have not yet been published in the official materials reviewed.
