In Slovakia's High Tatras, male racers carry 60 kg uphill, including a 30-litre keg of beer. Women carry 20 kg, often beer cases. Loads are strapped to wooden frames.

The Sherpa Rallye, starting above Starý Smokovec, finishes at Zbojnícka chata, 2,000 meters above sea level. Supplies left at the hut serve a purpose. Read more trail coverage.

The race began in 1985 to unite mountain porters and stock remote huts for winter. It also helps ensure the hut is fully supplied before winter. Related: Women-only trail races aim to boost female participation.
