Geneva and Neuchatel have held test events to measure potential infections.
On Friday evening 600 were allowed in the Victoria Hall in Geneva – half its normal capacity – for a concert by the Geneva Chamber Orchestra.
All those attending had to have been vaccinated and tested.
In Neuchatel, the Swiss Canyon Trail went ahead with 2,000 runners.
Both events will be monitored to check for any infections and spread of the virus.
