Young Christians are setting off this weekend to walk a thousand miles from the G7 summit in Cornwall to the site of the UN COP26 climate conference in Glasgow.
It's a symbolic act of faith and hope and walkers will be praying for climate justice along the route.
They'll be setting set off from Truro Cathedral on Sunday at 2pm. It's been organised by the Young Christian Climate Network and Christian Aid.
Young Christians have really been getting involved with the G7 summit, with lots of projects underway.
Premier's Josh Carter spoke to 17-year-old student, Toby Grier, about his feelings regarding the G7 summit.
