Since registration for the Khao Yai trail run filled up in a record two hours last month, we’re here to warn hardcore runners well in advance for the upcoming Mae Hong Son's Ultratrail Panoramic Run.

 

Mark Nov 30 on your calendar as the date registration closes (www.teelakow.com) for the super-intense “double 100” challenge: that’s your choice of either 100 miles (160km) or 100km, making it the longest trail run in Thailand.

 

The race sets off on Dec 9-11 from Mae Hong Son province and makes its way to tourist utopia Pai. Entry for the 100 miles costs B7,500 and 100km B5,500.
