In August, all registered runners will receive a link to book a slot time during which they want to start.

- We will have 30-minute castles with 30 people per castle. It won't be a starting shot either, but you start under one's castle, says Gyldén.

The latest castles will be around 17 every day for a month.

If you do not want or can go to Lidingö during the month, you can run your distance at home and and report the time, but then you end up in another result list.
