Beyond racing · We Run for Tibet · 5 to 7 September 2025
The finish at the United Nations, Geneva. September 2025.
Endurance, identity and purpose.
As a Swiss-Tibetan, the project had a deeply personal meaning for me. Together with the Swiss-Tibetan Friendship Society (GSTF), I co-initiated We Run for Tibet to combine endurance sport with awareness for Tibet.
The original event took place in March 2025, but I became sick shortly before the run and wasn’t able to complete it as planned. I decided to try again in September. This time very quietly. Apart from three people, nobody knew I would make another attempt.
In September 2025, I ran non-stop across Switzerland from St. Gallen to the United Nations in Geneva, covering 373 kilometres in 58 hours, largely alone and with only minimal support, and setting a world record.
The project went far beyond the sporting challenge itself. It brought together endurance, identity and purpose, attracted significant media attention — including coverage by 20 Minuten, RTS and Blick — and helped create broader visibility and awareness for Tibet.
