Sahara Ultra Marathon 100 KM

I'm going to attempt to run 100 Km over 2 days in the Sahar desert in blistering heat with day time temps reaching 40+ deg and night time temps as low as -10 . I'm doing this to raise awareness of mental health with in the armed forces raising as much money as I can for some amazing military charities that really do change peoples life's . Time for me to put my body / mind on the line to help others get out of there own dark places . This will proberly be the hardest thing I have ever done . Don't quite realise what I have let my self in for . But I will push the human boundaries and get the job done .
