CARRY
ATLAS CARRY
A strength challenge that dates back +1000 years to the highland games of Scotland. Summon Celtic strength to lift a 100 lb/45 kg stone up, carry it around a flagpole, and haul it back to the start. Female competitors must carry an equally difficult 75 lb/35 kg stone.

CLIMB
A-FRAME CARGO
A towering obstacle that takes after its name. This giant 'A' shaped structure will test both your dynamic footwork and fear of heights. Climb over the top and down as quickly as possible using only the webbing. This is hard to do fast, especially in wet conditions.
CLIMB
A-FRAME CARGO
CARRY
Barbed Wire Crawl
Wire obstacles were used during the Civil War to slow the enemy, and since then armed forces around the world have made this a staple of basic obstacle courses.

LEAP
FIRE JUMP
The iconic finish line obstacle. Some go for hang-time, others tap an ankle, tuck jump, or join hands with friends. Just don’t land in the fire.

CLIMB
INVERTED WALL
Whoever named this had no idea what inverted actually means, but the name stuck. With some practice, it's possible to run at it, flip over the top, slap the face of it with one arm, and catapult down the other side. You will surely be more popular if you can do this.
CLIMB
INVERTED WALL
CARRY
BUCKET CARRY
Often involves a steep wooden ladder on two sides of a flat crossing, sometimes made from stacked cargo containers. It's high, and after running your legs off, you'll want to take this carefully.

STRENGTH
HERCULES HOIST
"Herc" is essentially a heavy sandbag attached to a rope and pulley system. Each competitor must pull on enough rope to raise the weight to the top then gently lower it back down without it free-falling.

HERCULES HOIST
SWING
MULTI-RIG
The Multi-Rig comes in many configurations, starting with Sprint and going right up to Ultra. Sometimes you’ll encounter rings, other times rings and pipes, and sometimes ropes, baseballs, and other tricky things to grab onto.

CLIMBING
ROPE CLIMB
Gym class was nothing. At the top of the 16 ft / 4.8m rope is a bell that must be rung with your hand. All Spartan race levels feature rope climb, and it becomes progressively more difficult in cold, wet, or muddy conditions.
CLIMBING
ROPE CLIMB
CARRY
SANDBAG CARRY
Spartan sandbags come in various shapes and weigh 60 lb (27 kg) for men / 40 lb (18 kg) for women. This isn't like carrying a bag of groceries.You'll usually find the Sandbag Carry on uneven ground, in mud, or if you’re particularly (un)lucky, up the side of a ski slope.

CLIMB
SLIP WALL
Rolling Mud is a series of deep water-filled mud pits that make your life difficult by filling your shoes and socks with wet and sticky mud. It’s called “rolling” because you’ll need to wade through several of these pits of brown mud and water.
CLIMB
SLIP WALL
THROW
SPEAR THROW
The obstacle that has defined Spartan World Championships. Your challenge is to choose a spear, fire at a target 25 ft / 7.6 m away, and hope it sticks in the target without falling out. Once you try Spear Throw once you'll want to come back and try again, and it's a lot of fun.
THROW
SPEAR THROW
CLIMB
WALLS
Starting at 4 feet and reaching up to 8 feet high, walls require a combination of strength, agility, coordination, and technique to scale. As always, Spartans are encouraged to attack the course together but conquer all obstacles alone, and walls are no exception.
