Kajang Ultra Marathon 2027

Kajang Ultra Marathon 2027 is a track-based endurance running event at Stadium Kajang in Selangor, Malaysia, scheduled across 24 and 25 April 2027. Organised by Lumen Sports, the programme combines fixed-distance ultras with timed endurance categories: 100km, 50km, 24 Hour, 12 Hour and 6 Hour. The organiser describes the venue course as a 400-metre asphalt track, making this a very different challenge from a point-to-point road ultra or technical trail race.

The event begins at 07:30 on Saturday and runs through to 07:30 on Sunday. Stadium Kajang is in central Kajang and is accessible by public transport via Stadium Kajang MRT station, which is useful for runners and crews travelling without a car. Because the race is based on a short repeating circuit, participants remain close to the event hub throughout their effort rather than moving through remote checkpoints.

The organiser operates the event as a bring-your-own-bottle and bring-your-own-cup race to reduce disposable cup waste. Runners are advised to prepare their own nutrition and hydration strategy and the published recommended equipment includes food or energy supplies, salt replacement, basic first-aid items, sun protection, rain protection, anti-chafing products and an emergency blanket. A bag-deposit service is available at the event site, subject to the organiser's published bag rules.

All participants must be at least 18 years old. The organiser may conduct mandatory-item checks, requires race bibs to remain visible, prohibits unauthorised assistance and short-cutting, and provides event medical support and organiser-arranged insurance. Participants are expected to follow crew instructions and any category-specific cut-offs or race briefing requirements.

Race-pack collection requires either the participant's race confirmation slip or identification card. Collection on behalf of another runner requires a printed Letter of Authorization, while indemnity forms are completed digitally at the collection counter. Exact 2027 collection hours, current entry fees and the registration closing date were not clearly published in the accessible event information at the time of listing, so entrants should confirm those details on the official registration page before making travel plans.
