Tsomgo Ultra 6.0 2027 - Gangtok, Sikkim, India

Tsomgo Ultra 6.0 returns to Gangtok, Sikkim, on Sunday, 14 March 2027 for a demanding run into the eastern Himalayas. Organised by local runner collective Kudum with Serenity Home, the event combines mountain scenery with sustained climbing, thin air and rapidly changing conditions. Its courses begin around Ganesh Tok and climb the road towards Tsomgo before turning back towards Gangtok.

Course and altitude

The organiser's 2027 course guide confirms four distances:

• 75K ultra: approximately 2,959 m of climbing, reaching 3,757 m above sea level. Scheduled start: 5:00 am.
• 42K marathon: approximately 1,425 m of climbing, with a high point of 3,017 m. Scheduled start: 6:00 am.
• 21K half marathon: approximately 746 m of climbing, reaching 2,521 m. Scheduled start: 6:30 am.
• 10K: approximately 375 m of climbing, reaching 2,213 m. Scheduled start: 7:00 am.

All times are local Indian Standard Time (UTC+5:30). The routes follow Sikkim mountain roads rather than conventional flat city streets. The 75K is the headline endurance challenge, but even the shorter courses demand respect for altitude and elevation gain.

What to expect

The route starts around 1,968 m and climbs towards views of Gangtok's mountainous surrounds. Weather can change quickly, with wind, rain and cold conditions possible. The organiser describes aid stations historically spaced about 5–7 km apart and medical support throughout the course. Runners should train for prolonged uphill and downhill efforts, allow appropriate time to acclimatise and carry clothing suited to mountain weather.
