Inspired by David Goggins, Rishi and Sam are attempting the 4x4x48hrs Challenge.
The challenge they have given themselves really is going to push them to their limits as it means running 4 miles, every 4 hours, for two full days straight. This means limited time to rest and we would imagine, blisters once the challenge is complete.
Of course, Rishi and Sam are attempting this challenge for a wonderful cause.
Rishi said, ''We chose Alzheimer's Research UK as Sam's Grandad has suffered from Dementia for over twenty years. This is the chance to give something back an amazing charity that do so much important work.''
• Dementia affects over 850,000 people in the UK and numbers are increasing.
• At £26 billion each year, dementia costs the UK economy more than cancer and heart disease combined.
• £50 could provide access to specialist equipment for studying cells.
• £120 could support complex protein analysis.
So far, they have raised a staggering £4800 for Alzheimer's Research UK after seeing themselves a target of £4000.
Sam said, ''Thank you SO much to anyone that has donated to the 4 x 4 x 48 Challenge. Rishi and I are beyond grateful for your generosity, we appreciate you! Any donation, large or small is welcome, we cannot thank you enough.''
