The Rovaniemi 150 is a 150km foot race through the countryside around Rovaniemi in Lapland - just inside the Arctic Circle. I think it will take between 30 and 42 hours to complete, dependent on the depth of snow and temperatures which could drop as low as -30C. This is even further than my last silly project, so please support Combat Stress as much as you can - they're an amazing charity and it will help spur me on when my toes are freezing!

Combat Stress is the leading UK charity specializing in the care of Veteran’s mental health. They currently support 5,400 ex-Service men and women with short-stay clinical treatment, outpatient treatments, and Occupational Therapy. They also run a UK-wide outreach program and a free 24hr helpline for veterans, serving personnel and families.
