Merbabu SkyRace Central Java 2027

Merbabu SkyRace 2027 is a demanding mountain trail-running weekend based at Thekelan, Desa Batur, Getasan, Semarang Regency, at the foot of Mount Merbabu. The organiser's 2027 programme runs across Saturday 5 June and Sunday 6 June, with a race village and start/finish at Base Camp Thekelan. Courses explore steep mountain trails, forests and exposed high ground around the 3,145-metre volcano. This is not a flat road race; participants should prepare for sustained climbing, uneven footing, changeable weather and mountain-safety rules.

Eligibility and mountain safety

The organiser requires prior race completion for the longer races: 5K experience before entering 10K; 10K before 20K; 21K before 40K; and 30K before 50K. The 5K has no previous-race requirement, but entrants still need adequate trail fitness. Supporting proof of qualifying races may be required when registering.

Race rules specify visible bibs, weatherproof clothing, hydration capacity (at least 1.5 litres), charged phone, emergency supplies and other compulsory equipment. Carry personal nutrition and follow course markers, marshals and weather-related instructions. Aid-station and rescue access may be limited in remote terrain. Check the full official kit list and health requirements before paying.

Tickets, race packs and important corrections

Published race categories offer distinct local and expatriate entry prices, shown in the cards below. The official registration buttons link to an external queue/ticketing provider; current inventory must be checked at checkout. The general FAQ's reference to closing registration in April 2026 is outdated and cannot establish a 2027 closing date. Race-pack collection and a technical meeting are planned for the days before racing, but final pickup hours should be verified.

Actual distance warning: the organiser offers 20K and 40K, NOT 21.1K and 42.2K. ARC has no exact structured filters for 20K and 40K, so the 21K and 42K filters/cards on this listing are only approximate search categories. The official 20K/40K prices, times and limits are shown above; do not mistake the ARC filter for the race distance. For the same reason, refer to the latest race guide and GPX for measured course lengths.

The official site occasionally contains leftover 2026 wording (including a stray Saturday year), but its detailed race category date/time schedule and the other FAQ race-start entries consistently specify 5–6 June 2027. Check the official organiser website for amendments before travelling.
