organized a foot race that incorporated the natural obstacles of the course. There are now more than 30 annual ''survivalruns'' in the Netherlands which incorporate both natural and built obstacles and form an organized amateur competition. The HiTec Adventure Racing Series (1996 - 2002) was an early version of the contemporary race and included "special tests" (man-made obstacles with walls, nets, etc.), mountain biking, and kayaking. The Balance Bar races in the United States expanded on the success of the Hi-Tech series, including a televised national series and championships. The Muddy Buddy races in the United States were a national obstacle race series produced by Competitor Group from 1999 to 2013 and was the first major series to introduce mud elements and remove additional equipment. Muddy Buddy was the event format that transitioned

Contemporary races
There are many variations of obstacle race courses that accommodate a wide variety of athletes. Ninja races are typically 50 m to 100 m in length with many obstacles and little running. OCR track races are typically held on athletic tracks and vary between 400 m and 5,000 m. Cross country courses range from one mile and up, with most races between 5 km and 10 miles.
Longer endurance races vary up to 100 miles.
Obstacle Course Races with inflatable obstacles are becoming increasingly popular.

Notable events
Muddy Buddy
Muddy Buddy (1999 - 2010) was the first national OCR series in the United States emphasizing man made obstacles and mud. Unlike later OCRs it included a bike leg, making it a "ride and run" OCR. The event series was produced by Competitor Group and sponsored by Columbia in later years. Muddy Buddy ultimately went out of business under pressure from Tough Mudder and Warrior Dash which had simpler run-obstacle formats.

Since first appearing on the show, the Rugged Maniac event has expanded to Canada, increased in sales from $4.2 million to $10.5 million before and after Shark Tank, expanded to 28 cities, and created a second race called "The Costume Dash 5K", which debuted in Boston in October 2015.
Rugged Maniac features 25 obstacles over a 5 kilometer (3.1 mile) course. It is designed to be more family-friendly and catered to people of all fitness levels, due to the shorter distance but larger number of obstacles. The run ends with an all-day festival of beer, food, mechanical bull riding, adult-sized bounce houses, and sponsor exhibition booths.
Spartan Race
Spartan Race (2010) was an outgrowth of the annual Death Race (started in 2005), with courses vary in distance and difficulty from "Sprint" courses (3+ miles with 20+ obstacles ), to "Super" (8+ mile with 20+ obstacles), and "Beast" course (13+ mile with 30-35+ obstacles). For endurance enthusiasts, Spartan also offers the "Ultra Beast" which is 2 times through the "Beast" course (later changed to "Ultra" for 30 miles), and the "Hurricane Heat" which involves tasks that set up the obstacle course the night before. Average finishing times for the events range from 30 minutes to 6 hours, depending on the particular course and fitness level of the racer. Race venues are located around the world and have included ski slopes, state parks, paintball parks, and more. Any competitor who completes a Sprint, Super, and Beast in one calendar year (Jan. 1 - Dec. 31) is said to have completed the Spartan Trifecta.

from 2012 until 2015 when it was moved to Squaw Valley near Lake Tahoe. The World Championship has been held in Squaw Valley in Olympic Valley, CA near Lake Tahoe every year since 2015. Prizes for World Championships in 2016 included: Overall Champions (Men' and Women's) 1st place $15,000, 2nd place $10,000, 3rd place $5,000, 4th place $4,000, 5th place $3,000; Elite Beast Championship (Men & Women's – 40+) 1st place $500, 2nd place $200, 3rd place $100; and Elite Ultra Beast Championship (Men & Women's) 1st place $1,000; 2nd place $500; 3rd place $250; 4th place $100; 5th place $100.

The first Spartan Race World Championship was held in December 2011 in Glen Rose, Texas as an eight-mile Spartan Race course comprising 36 obstacles and included a US$20,000 prize purse. Beginning in 2012, the Spartan Race World Championships were held annually in Killington, Vermont, and at Squaw Valley, CA since 2015 with a total of $500,000 in cash and prizes.
Spartan Races have occurred in more than 30 other countries around the world. According to event organizers, obstacles vary from race to race. Obstacles during a Spartan Race can include climbing under barbed wire, wall climbing, mud crawling, a javelin throw, a rope climb, heavy object carries, slippery walls, a zig-zag log jump, steep mud climbs, tire flips, and rope swings.
Spartan Races hosted the Kids World Championship which was held on November 17, 2018. Boys and girls between the ages of 10 and 13 from around the world participated in the race.
Tough Mudder
Tough Mudder's first event was held in May 2010. The Tough Mudder is not technically a race and is instead focused on teamwork and completion of the event rather than finishing under a certain time.
Tough Mudder courses are between 10 and 12 miles and contain various military-style obstacles.
The final event of the Tough Mudder season is the World's Toughest Mudder. This is a 24-hour event in which competitors will run a shorter Tough Mudder course that has much more intense obstacles than a normal Tough Mudder and is designed to be more grueling as well. The goal for a participant in World's Toughest Mudder is to complete as many laps as possible within a 24 hours period. The athletes (solo male, solo female, team) who complete the most laps are declared the World's Toughest Mudder. The top male and female each receive $10,000 and the top team receives $12,000 (total).
Warrior Dash
The Warrior Dash was founded in 2009. Because Warrior Dash does not assign penalties for skipped obstacles, it is often considered an obstacle course event rather than a race. While Warrior Dash does not meet all the requirements to be considered a race, organizers do award their top finishers with non-cash prizes. All finishers receive a "warrior helmet" – a horned helmet.
As a shorter event, winning times for a Warrior Dash may be as short as 15 minutes. While Warrior Dash features many of the same obstacles found at other races such as mud crawls, water features, and
