Ranking
Most Dangerous Sports 2026
The 20 lowest-scoring sports we rate, from wingsuit flying and road racing to boxing and cave diving. Each score combines the chance of dying in micromorts with the risk of serious injury, how much skill and equipment cut the risk, and how far you are from help. The list puts the most dangerous first. It includes sports you do yourself, not rides or travel.

The ranking
Extreme and high altitude
Motorcycle Racing
Racing on closed public roads such as the Isle of Man TT is among the deadliest sports we rate, at several thousand micromorts per rider per race meeting, close to an Everest expedition. Circuit racing on purpose-built tracks with run-off and gravel traps kills far fewer riders, though broken bones remain common.
Score 21, grade FExtreme and high altitude
Wingsuit BASE jumping
Flying a wingsuit off a cliff or mountain is among the deadliest things people do for fun. A BASE jump carries about 200 to 800 micromorts, and wingsuits were involved in 137 of 223 recorded BASE deaths in 2007–2017. Wingsuit skydiving from a plane is a different and much safer activity.
Score 28, grade FExtreme and high altitude
BASE jumping
BASE jumping is among the most dangerous activities on our list. One jump carries a 200 to 800 in a million chance of death in studies from Norway and Switzerland, and wingsuit flying now accounts for most of the dead.
Score 31, grade FExtreme and high altitude
Mountaineering
Climbing glaciated peaks such as Mont Blanc, Rainier or Denali is one of the riskiest common sports. Studies put one Rainier ascent at about 300 micromorts, and Denali park data give about 1,400 per attempt in 2021–2025. Most deaths are falls, often on the way down, followed by avalanches and rockfall.
Score 32, grade FIndividual sports
Boxing
Training and fitness boxing are low risk, but a professional fight is one of the riskiest things a sportsperson does in a single evening, at about 1 brain-injury death per 5,000 bouts. The bigger long-term threat is the build-up of head blows over a career, which is linked to dementia in professional boxers.
Score 41, grade DExtreme and high altitude
Cave diving
Cave diving is among the riskiest sports we score per outing. British data for 1981–2005 give about 250 micromorts per dive overall, about 35 to 70 for qualified, experienced divers and nearly 900 for divers without cave training. Most deaths follow the same path, getting lost or low on gas with no way straight up.
Score 48, grade DExtreme and high altitude
Ice climbing
Ice climbing is riskier than rock climbing but rarer, so deaths are few in absolute terms. We estimate roughly 15 to 40 micromorts per day on frozen waterfalls. Most injuries are cuts and bruises from falling ice, while deaths come from leader falls, collapsing ice and avalanches.
Score 54, grade DIndividual sports
Horse racing (jockeys)
Each race is short, but jockeys ride hundreds of them, so the risk adds up. Studies from Australia, Britain and France put a flat ride at about 3 to 7 micromorts and a jump ride higher. Injuries are common, and in California the most frequent cause of a fall was a horse breaking down or dying mid-race.
Score 57, grade COutdoor and adventure
Backcountry Skiing
A day of ski touring carries about 13 micromorts on our estimate from Swiss data, roughly ten times a day on the pistes. Avalanches cause most deaths, and the forecast danger level, the slope you pick and a fast companion rescue decide most of that risk.
Score 58, grade CExtreme and high altitude
Free diving
Breath-hold diving for seafood carries about 20 micromorts per trip on New Zealand counts (roughly 15 to 30), several times the risk of a scuba dive. Blackout from lack of oxygen is common and gives no warning. With a trained buddy watching every dive it is rarely fatal; alone, it usually is.
Score 59, grade CExtreme and high altitude
Paragliding
Paragliding is riskier per flight than skydiving or scuba diving, at about 14 micromorts per flight on the best UK estimate. Almost all accidents come from pilot decisions and handling rather than equipment, so the weather call and staying within your skill level matter most.
Score 59, grade CIndividual sports
Motor Racing (Cars)
Modern circuit car racing, from club events to Formula 1, is far safer than it was, thanks to survival cells, HANS devices, the halo and fast medical response. Crashes and concussions are still common, and rallying on public roads carries many times the risk of a circuit.
Score 61, grade CExtreme and high altitude
Hang gliding
Hang gliding carries about 8 micromorts per flight, roughly twice a skydive and a little below paragliding. Most accidents happen at launch or landing and come from pilot decisions, so training, a strict pre-flight routine and the weather call matter most.
Score 62, grade COutdoor and adventure
Rock climbing
Outdoor rock climbing in the mountains carries about 3 to 7 micromorts per hour, so a long day on alpine rock can match several skydives. Indoor and bolted sport climbing are far safer. Most serious accidents come from falls, rockfall and rope-handling mistakes such as belay, lowering and abseil errors.
Score 66, grade CIndividual sports
Triathlon
A triathlon is riskier than a marathon, at roughly 10 micromorts per race, and the danger is concentrated in the opening swim. Most victims are middle-aged and older men, often with heart disease they did not know about. The bike leg adds crash injuries, and training brings overuse injuries.
Score 66, grade CTeam sports
Rugby
Death on a rugby pitch is rare, roughly half a micromort per adult match on South African data. Injuries are the real cost. Concussion is the most common match injury in English professional and community rugby, and former elite players face a higher risk of neurodegenerative disease.
Score 69, grade CIndividual sports
Horse riding
The risk of death on a single ride is low, about half a micromort on the best-known estimate, but riding injures many people, mostly through falls and kicks. Head injuries cause most deaths, older and male riders are more likely to die when hurt, and a certified helmet is the single best protection.
Score 70, grade BExtreme and high altitude
Skydiving
A single skydive carries a small but real risk, about 4 in a million on recent US figures, higher in older data. Most deaths and injuries now come from landing errors under a working canopy, not from parachutes failing, so training and conservative canopy choice matter most.
Score 72, grade BTeam sports
American football
Deaths in organised US football are rare, under 1 per 100,000 high-school players a season, and most are from heat stroke and heart problems rather than collisions. The bigger concern is the brain. Concussions are common in games, and the odds of CTE rise with every year played.
Score 73, grade BIndividual sports
Skateboarding
Skateboarding injures often, mostly wrist and ankle fractures from falls, but rarely kills. The deaths that do happen are mostly skaters hit by cars, and per mile a skateboard in traffic is riskier than a motorcycle. Skateparks without traffic are much safer, and a helmet prevents the worst head injuries.
Score 73, grade B
Which activities count as sports here
We rate activities in five groups. This ranking takes every page in our Team sports and Individual sports groups, plus the outdoor and extreme activities you do yourself as a sport: climbing and mountaineering, diving, flying under a canopy or wingsuit, skiing and boarding, surfing, paddling, sailing, mountain biking, and racing motorcycles. We leave out travel, pages about single mountains, rides where an operator or pilot is in charge, motorised leisure riding and hunting. The rule is about what you do, not how risky it is.
How the ranking works
Each sport has four scored factors. Fatality risk counts for half, measured in MicromortA one-in-a-million chance of death. It lets you compare the risk of very different activities on one scale.More in the glossary, a one-in-a-million chance of dying. Serious injury risk counts for 25%, controllability, how much training and good choices reduce the risk, for 15%, and rescue and environment, how remote you are and how fast help comes, for 10%. The fatality score follows a log scale, so every doubling of risk costs the same number of points. The full rubric is on how we score activities.
The order is the sport scores sorted from the lowest up, so the most dangerous come first. When we update a page with better data, its place changes, which is why this text does not quote scores.
Risk units differ between pages
A MicromortA one-in-a-million chance of death. It lets you compare the risk of very different activities on one scale.More in the glossary figure means little without its unit. Skydiving is measured per jump, mountaineering per ascent, road racing per rider per race meeting, and ice hockey per session or per high-school season. A risk that looks tiny per session can add up over a year of training and matches, and a single expedition can expose you for weeks. We turn each figure into a score on the same scale, but when you compare two sports yourself, check that the units match.
What the most dangerous sports have in common
Most sports near the top share three things. A single error is often fatal, as in a fall while climbing, a mistake in a wingsuit or a crash at racing speed. The setting is unforgiving: cliffs, flooded caves, glaciers and high-speed public roads, far from fast medical help. And part of the risk is outside your control, from avalanches and rockfall to mechanical failure and weather.
Team sports rarely appear at the top. Deaths in them are rare and are often heart problems rather than injuries, though concussion and broken bones make them riskier than their death rates alone suggest.
Questions
What is the most dangerous sport in the world?
The sport at the top of this list has the lowest score we give any sport right now. The front of the list is filled by sports where one mistake or one gust can kill, such as racing motorcycles on closed public roads, wingsuit flying, BASE jumping and climbing high glaciated peaks. Their risk per outing is hundreds or thousands of times that of a team sport.
What is a micromort?
A one-in-a-million chance of dying. It lets you compare very different risks on one scale. On our pages, an ordinary recreational run is well under one MicromortA one-in-a-million chance of death. It lets you compare the risk of very different activities on one scale.More in the glossary, a skydive is a few, a scuba dive a few, and a BASE jump hundreds.
Can I compare the micromort figures on different pages directly?
Only with care. Each page gives the risk in the unit that makes sense for that sport, per jump, dive, race, ride, session, day, hour or season. A sport with a small risk per session can add up over a season of training and matches, and one expedition can last weeks. Read the unit on each page before you compare.
Do injuries count, or only deaths?
Both. The risk of death counts for half of the score, serious injury for a quarter, and controllability and rescue for the rest. That is why boxing sits among the most dangerous sports. A professional fight carries a real risk of death, and cuts, concussions and the long-term harm of repeated head blows weigh on its score too.
Which sports are left out of this list?
Travel and getting around, such as motorcycling or cycling on the road; single mountains such as Everest and K2, which the mountaineering page covers; rides run by an operator, such as bungee jumps, rafting trips, balloon and helicopter flights and zip-lines; motorised leisure riding on quad bikes, jet skis and snowmobiles; and hunting. Each has its own page.
Does a dangerous sport mean I should not do it?
No. The score tells you how much risk you take on and how much of it training, equipment and choices can remove. In most of these sports, a course, the right gear, a partner and the discipline to turn back cut the risk sharply. Each page lists the steps that matter most.
