What is the toughest obstacle you have ever overcome? For Will Mullin his toughest challenge has been inspired by a cause that is very close to his heart. This April, Will is taking on The Marathon des Sables- a race that the Discovery Channel has dubbed ‘ the toughest footrace on earth’.

The 35 year old father of 2 will run 251 km – the equivalent of five and a half marathons in six days, in the Sahara’s gripping heat. All he will be given is water and space in a tent to sleep in. The race rules mean Will must be self sufficient, and carry his own equipment and food. He will also need room for dedication, drive and sheer determination.

So why is Will taking on the toughest race on earth- in temperatures varying from a chilling 4 degrees to a burning 48 degrees?

Will is completing this tough challenge in order to raise €20,000 for Biobank Ireland. Biobank Ireland is a charity promoting a biobanking network in Ireland that aims to bridge cancer research & care. Biobank Ireland aims to bring a better understanding of cancer which will mean improved treatments.

Will has a special reason for raising these much needed funds. His Mum and Dad are cancer survivors – one of the reasons his Dad beat cancer was because of the drugs that were developed through biobanking. Now Will wants to give something back, and help other families with this life saving, invaluable and much needed research.

While you are not being asked to overcome the sandy Sahara, the unbearable thirst or run more than 50 kilometers a day, you can donate to this cause. In supporting Will and Biobank Ireland you will be fast-tracking cancer research for improved diagnosis and treatment. Doesn’t that sound like an amazing investment?
