A State Tourism Board's Marathon
The Selangor Marathon (SELMAR 2026) is organised directly by Tourism Selangor, offering two distances: the 42.195K full marathon and 21.1K half marathon, starting at Persiaran Flora, Cyberjaya. [1] That state-tourism-authority organisational model gives the event genuine institutional backing, distinct from the sportswear, beverage, fintech and bank sponsors covered elsewhere in this research.
Cyberjaya: Malaysia's Aspiring Silicon Valley
Cyberjaya is a planned city in Sepang District, Selangor, established on 17 May 1997 as part of Malaysia's Multimedia Super Corridor (MSC) initiative -- the country's first 'intelligent city,' designed to serve as its technology and innovation hub. [2] The name is a portmanteau of 'cyber' and 'Putrajaya,' reflecting its adjacency to and shared development history with Malaysia's administrative capital. With a 2020 population of just under 50,000 across 28.94 sq km, it hosts numerous multinational companies and data centres.
Marathon and Half Only
Unlike most races in this research batch, which offer a broad spread from 5K to full marathon, SELMAR sticks to just two serious distances: the full 42K and the 21K half. [1] That focus signals a race aimed squarely at committed distance runners rather than casual or family participants.
Wide, Modern Roads for Racing
As a purpose-built planned city adjacent to Putrajaya, Cyberjaya offers wide, modern boulevards well suited to marathon-distance racing -- similar in spirit to the purpose-built infrastructure seen at HSN Putrajaya and Garmin Run Malaysia's Putrajaya venue, both covered elsewhere in this research batch.
Should You Run It?
If a state-backed marathon through Malaysia's purpose-built tech hub appeals -- especially if you want a focused full or half marathon distance without a crowded field of shorter fun-run categories -- the Selangor Marathon on 1 November 2026 is a solid, institutionally credible pick.
