30 May 2026·Amstelveen·50 km, 100 km

The Sri Chinmoy 50K & 100K race is a loop-based ultra in the Amsterdamse Bos near Amstelveen. On Saturday 30 May 2026, runners choose 50 or 100 km on a shaded 2,226.42 m loop, with start and finish at De Uitkijk on Nieuwe Kalfjeslaan opposite Hurley hockey club. Each pass brings participants back to the aid station, while the repetition of the same loop makes pacing and lap management very tangible. The 100 km starts at 09:00 and has a 12-hour limit; the 50 km starts at 12:00. The Sri Chinmoy Marathon Team gives the race a well-supported, calm setup in which ultrarunners can keep working on their own rhythm for a long time.
