Edinburgh Critical Mass are having a special ride to celebrate how more bicycles (and fewer cars) can help nature recover.
The Scottish Rewilding Alliance, who will be handing their Rewilding Nation Charter to the Scottish Government on 3rd December, will be joining the event.
Everyone is encouraged to wear something/decorate their bikes with a Scottish wildlife theme, or to make a placard highlighting the link between cycling and nature.
Meeting on Middle Meadow Walk and finishing at The Parade Ground in Holyrood Park.
