A group of trekkers on their way to Everest Base Camp. Next week, I set off on one of the biggest adventures of my life so far – trekking to Everest Base Camp. Over 11 days, I’ll hike a 80 miles (130km) roundtrip, and climb around 8,000ft (2,438m) to reach the famous camp at the foot of the world’s tallest mountain. Should I be nervous? My visa is in hand, my vaccinations are boosted, and all my shiny new kit is steadily piling up in my open suitcase.
