We are doing a 12 hour obstacle course which consists of 20 obstacles within a 5 mile lap. Our challenge is to complete as many of these laps as we can between 1900-0700. We choose alzheimer's as this charity is close to home. Our Grandma developed this disease in 1995 and sadly died aged 92 in 2012 seeing her with this disease makes us want to raise money to help raise money for those with this disease in the future.
