There were hundreds and hundreds of burnt-out cars. The entire marketplace had been burnt to the ground. They were attacking anyone western, who they associated with the UN, who they felt was supporting the other side. 'One guy tried to attack me, and threatened to kill me. 'It was happening in the streets around me,' said Wood, whose experiences will be televised in 2015. Dozens were massacred nearby and, with no seats left on a UN plane flying from the region, Wood and his guide Boston were trapped. At the town of Bor, Wood found himself caught in the middle. Within days of the start of Wood's walk, war broke out between supporters of the president, Salva Kiir, and his deputy, Riek Machar.

It was South Sudan that had Wood fearing for his life. In Uganda, an experienced reporter assigned to cover Wood's journey collapsed and died of heatstroke. In South Sudan, Wood walked through a civil war. In Sudan, Wood battled temperatures as high as 62C (144F).

'It's easy to find somewhere to stay, the food is good, it's pretty straightforward compared to Sudan and South Sudan.' 'This is probably the easiest stretch of the trip,' said Wood on Monday, halfway through his daily 25-mile march, straining to be heard above the midday calls to prayer. By September, Wood should be at the shores of the Mediterranean, 4,250 miles from where he started last December at a hole in the ground in Rwanda. In less than three weeks, he will be in Cairo, within sight of the pyramids. On Sunday, Wood was in Luxor, passing the burial ground of Tutankhamun.
