The 2016 BMW GS Trophy is rolling along as riders covered almost 450 km in the last two days, travelling from Mae Sariang to Doi Inthanon yesterday and to Chae Son today.

Day 5 was a long riding day, as the 270 km route took riders from Mae Sariang to Doi Inthanon. It was a fast-paced ride, once again covering almost every type of road surface imaginable. Main roads in northern Thailand are pristinely paved and smooth, with fast, flowing sweepers, while other roads are either dirt, or concrete, or were once paved with only spotty patches of asphalt remaining. Or they are simply cow trails. And if you think the Tail of the Dragon in North Carolina is twisty—all roads here are dragon’s tails!

He wasn’t kidding. Although 10 km doesn’t sound like much it took us about one and a half hours to cover the distance.

The foot-wide track often flanked the side of a steep hill, where one wrong move would send you off the edge and down quite a long way. If you were lucky, trees would break your fall. The hill was so steep footpegs sometimes scraped on the side. Exposed tree roots often nudged the front wheel towards the edge.

Of course, before exiting this crazy trail, we had to climb a steep hill, littered with loose rock. About half the riders got stuck on the way up.

Tomorrow we return to the starting point in Chiang Dao, where riders will partake in the final riding test.
