Iain Ward, 33, came face to face with this question over two years ago when he was diagnosed with terminal brain cancer. He has now turned his focus to breaking the world record for the most money raised, for a single marathon. And he is hoping to do this by gaining sponsors through his social media platforms.

As Sally Orange sits on the other side of a Zoom call to us, we can't help but think about how this is probably her last chance to relax for a very long time. The army veteran and physiotherapist exudes a quiet energy, putting us in no doubt that the series of challenges ahead that she has set for herself will not only be endured, but conquered.

When we speak with Charlie Walker for this feature he is relaxed, with verdant hanging plants on the shelves behind him framing his profile. It's a stark contrast to the environment that he'll be spending 3 months in from 12th February: ski trekking 1000 miles along the frozen Lena River in Arctic Siberia. It's the coldest inhabited place on earth, with temperatures reaching -50°C.

Life can change in the blink of an eye. I learnt that the hard way on the morning of the 12th July, 2018 whilst returning into Cheltenham after dropping my dogs off at the kennels.
