The world’s toughest events take the bravest of riders across hundreds of miles, traversing dust-covered plains, up thousand-meter-high mountains, through dense jungle, over snow, and into water, with even the most hardened professional riders finding themselves pushed to their limits when taking part.
Here are five of the most grueling and hardcore mountain bike events from around the world, never to be underestimated with some having stringent entry criteria, these beauties will challenge every ounce of your mental and physical strength.
Crocodile Trophy, Australia
For 26 years the Crocodile Trophy has challenged racers from all over the World to compete in an ultra-endurance mountain bike race and makes The Croc Trophy one of the oldest and possibly most iconic mountain bike stage races in the world.
The Crocodile Trophy takes nine days to complete and its hot, North Queensland temperatures can be around the 30 mark with hotter days being upward of 40 degrees Celsius. Throw in a lack of shade and you’re talking about serious sun exposure, so don't forget your sun protection and water, and bring plenty of it.
The race itself is over seven stages and around 600km with over 10,000 meters of climbing, all in the baking heat of the Australian Outback. It is unquestionably one of the world's hardest races, and that’s before any unexpected encounters with the infamous razor-toothed reptile.
The 2023 event is from 5th-11th November with entries starting at AUD 2,850. To register and more information check out Crocodile Trophy.
Iditarod Trail Invitational 1000, Alaska
Racing a mountain bike self-supported in freezing temperatures in remote and inhospitable wintery conditions may not seem particularly attractive to most, but if it does appeal then this is the race for you. The Iditarod Invitational takes place over 1,000km of the Alaskan wilderness in around 30 frozen days and nights and is a test of resilience as much as a race to the finish.
The Iditarod Trail Invitational has built its reputation on notoriously inhospitable conditions and minimal outside support. To even gain a place you must have completed the shorter ITI 350 race and demonstrate a mastery of winter survival skills, navigation, and self-reliance for the unforgiving Alaskan wilderness you will experience.
Participants must carry all the supplies they need, but they can stop at remote villages on the route and use supplies that they've forwarded to the villages before the race. Despite the extremities of this Alaskan monster, Iditarod is incredibly popular with limited places available. The 2023 race already has a waiting list open with more information available at Iditarod Trail Invitational.
Yak Attack, Nepal
Altitude, temperature extremes, harsh living conditions, and very tough terrain make the Yak Attack one of the hardest mountain bike races around. Taking place in the mighty Himalayas, comprising of eight days, covering 280km, and with a total altitude gain of over 9,000 meters, this race throws every obstacle under the sun at the adventurous mountain bike riders daring to take it on.
Climbing to its highest point at 5416 meters above sea level, Yak Attack is, without doubt, the highest mountain bike race on Earth, and also has the highest timed enduro mountain bike stage from 5416 meters down to 2800 meters in just 8km of mind-blowing descent.
The 2023 edition will follow a similar format to 2022, flowy single track and epic descents with the snow-capped mountains as a backdrop. Three very unique loops around Besi Sahar, Manang, and Kagenbi will bring eight epic days of the most exciting and intense racing you are likely to ever experience.
If you’re up for a challenge, Yak Attack is from 17th - 29th November and entries start at $2,495. To submit an application and learn more visit The Yak Attack.
La Ruta, Costa Rica
Born in 1993, La Ruta in Costa Rica is the world's first multi-stage mountain bike race created by Mountain Bike Hall of Fame Inductee Roman Urbina. La Ruta has crossed the North American continent from the Pacific to the Atlantic on 28 occasions and for its 29th edition, the route is reversed.
Departing from the hot and fertile Caribbean lowlands on the Atlantic coast and passing through 20 microclimates before reaching the Pacific after three days of intense mountain bike racing.
This is one of the most difficult events an athlete can enter, between its sea-level start and finish, the 275km route crosses five mountain ranges forcing you to climb an elevation gain of 12,000 meters. You will go from the sweltering humidity of the rainforest to frozen volcano peaks and experience one of the most biodiverse countries in the world.
With a prize purse of $12,500 for both male and female racers La Ruta attracts mountain bike racers from across the world, the competition is fierce and so is the scramble for places. Currently sold out, anyone wishing to join a waiting list can do so at La Ruta.
Iron Bike, Italy
Iron Bike claims to be the world’s hardest mountain bike race and the numbers back this up, eight days, 700km, and 26,000 meters of elevation. Iron Bike is a bucket list ticker for any mountain biking stage-racing masochist.
Famed for its amazing Italian Alps scenery and race organization this mountain bike adventure has a high attrition rate, with only 50 percent of participants lasting the full week, with the descents being just as demanding as the 26,000 meters of climbing (just mentioning that again!)
This is not a challenge that novices should even consider taking on with many finishers reporting that they have been unable to walk for days afterward. At least they can bathe in the glory of having conquered one of mountain biking sternest events.
Iron Bike is set for the 22nd to 29th of July and is limited to just 110 participants with places going fast you can grab a spot at Iron Bike.
