100 miles across a frozen lake in the depths of Outer Mongolia. By foot, bike or skates…

In a remote corner of North-Western Mongolia lies Lake Khovsgol: One of 17 ancient lakes in the World over 2 million years-old and which contains the World’s purest fresh water. The shores are lined with ancient stands of boreal forest and packed with Wolves. It is serene, hostile, stunning, intimidating. In winter, the ice freezes across its entire near-100-mile length to a depth of over a metre thick, creating for Rat Race the ultimate adventure challenge course. This is the Mongol 100 – the most surreal, audacious and hauntingly beautiful adventure challenge known to Man. The objective is to traverse the entirety of the lake from north to south, by any means: Foot, skate or bike.

This challenge is open to all comers. It is hard; make no mistake. Perhaps the hardest thing you will ever take on. Not just because of the physical challenge. It is cold. Very very cold. That cold will test everyone; whoever you are and however capable you are. But our mantra is for you to get to the start line and we will help you get to the end. And in so doing achieve something extraordinary.

A stunning adventure journey across the jungles of Central America from Ocean to Ocean…

Panama is literally the crossroads of the Americas – an exotic, steaming jungle isthmus that separates Pacific and Atlantic and course, home to the World-famous Panama Canal. Our coast to coast journey follows a stunningly bio-diverse route from one side of the continent to the other. Our route starts from the beaches of the Pacific coast and rises via land dotted with coffee and fruit plantations into mist-clad mountains at the continental divide of the Americas.

We then descend towards the Caribbean via an enormous UNESCO-protected primary jungle wilderness. Travelling this section fully self-supported, hammock and supplies on your back and machete in hand, we will emerge from this pristine jungle environment to the banks of a river. You will inflate your pack rafts and travel the remaining distance to the coast, having completed a true coast to coast adventure. It’s then time to kick off those jungle boots, board our fast boat transport and get onto ‘Panama time’ on the famous Caribbean party island of Bocas Del Toro.

They say Arran is Scotland in miniature. From dense forests and coastal scenery in the South to crumbling castles and dramatic mountains in the North, the Isle of Arran delights at every turn. Welcome to Ultra Tour of Arran – a 2 day off-road running adventure from Rat Race – the UK’s favourite adventure sports crew. 

We do events differently. And for this one, we love the notion of setting sail to a location ‘over the water’ where you will feel a million miles away, but where you are in fact within easy reach of the mainland. With a simple 55 minute ferry crossing and a bundle of easy logistics thrown in, we encourage you to raise your clan and bring them over with you, enjoy our basecamp vibe, camp, run and be merry. Don’t let its size fool you though – packing an Ultra into each day over a 2 day weekend you will rack up 60 miles with some serious vertical gain. The mountains are high, the glens deep, the forests enchanting and the coastal scenery stunning. enjoy our basecamp vibe, camp, run and be merry.

Multisport or trek-only.

Our adventure unfolds in the deep freeze of the Scandinavian north, well above the Arctic circle. The focus of the trip is the country tripoint of Scandinavia – the spot where Norway, Sweden and Finland converge. Our route will visit this tripoint and we will use 3 different disciplines on our course – 1 each per stage of travel.
This trip benefits from significant use of inclusive in-country equipment (snow-shoes, skis, fatbikes) which means it is relatively accessible without the requirement for you to provide too much specialist kit. You will need warm winter clothing of course and you should expect serious arctic winter conditions. This is a real Arctic challenge with a seriously tangible objective: 3 countries, 3 adventure activities, 3 different stages.
