Imagine cycling 100 miles. 160 km. The distance from London to Bristol. On a fully loaded bicycle, carrying tent, cloths, sleeping bag, food and everything else needed to survive outdoors. Cycling this far takes around eight hour's of constant pedaling - more if the wind's against you. To put that into perspective, running a marathon slowly takes around four hours. By  one's reckoning, cycling 160 km is tough.

Now imagine doing this not just once on one day, but doing it again day after day until you're 10,000 km form your starting point. That would be the same as cycling from London to Rome. Six times in a row.

I'm Tom Bramall, and this is exactly what I'll be doing this summer. On 24 June I'm heading to Alta in the far north of Norway. From here I'll cycle north for a few days until I reach Nordkapp, 500 km inside the Arctic Circle and the most northerly point on mainland Europe. This is where the trip begins. I'll head back south and cycle down through Finland, eastern Europe, and Greece. Then I'll head west, through Croatia, Italy, France and Spain until I get to Punta de Tarifa, the most southerly point in Europe and the last stop before Africa.
