This challenge of 30 marathons in 30 days across the desert is going to be tough!

With soaring temperatures exceeding over 40 degrees in places, and scorching sun, Spencer will run the equivalent of 5 x The Marathon Des Sables (known as the toughest footrace on the planet)

Covering 786 miles - it will be similar to running the entire length of the UK, only through desert.

This is an official Guinness World Record attempt for “the most consecutive marathons run on sand”, which makes it even more difficult. There are a number of rules that need to be followed for Spencer to be successful, including:

The whole attempt must be made on sand - either on a beach or sand desert zone

Spencer may choose to run barefoot or with shoes and may alternate throughout the attempt

The entire course must consist of only sand. For instance, a layer of sand over a field of grass would not qualify

All marathon runs must be finished within 6 hours to be eligible.

Right now, there are many people across the UK living in crisis. Small charities are working hard in our communities to support those who need it most, but they need your help to make sure nobody is facing life's toughest challenges alone.

Global's Make Some Noise - the official charity of Heart - funds small charities delivering vital life-changing services including food banks, mental health support, domestic violence helplines, community projects and other vital life support programmes.

By supporting Spencer on his 30 in 30 Challenge, you can help small charities changing lives across the UK.
