now on lap 5.  they're all insane

 

it's the most bonkers ultra marathon.  5 20 mile loops with over 50,000 feet of vertical.  The 3 lap version is known as the "fun run"

 

"The course itself, which has changed distance, route, and elevation many times since its inaugural run, currently consists of an approximate 20-mile (32 km) unmarked loop with no aid stations except water at two points along the route. Runners are allowed to study and copy the course map prior to the race, but once the race is underway they must navigate by their own notes alone. The loop begins and ends at the yellow road gate where the runners' and supporters' parked cars stay. Runners of the 100-mile version run this loop five times, taking a counterclockwise direction for loops two and four, followed by each runner alternating direction on loop five, after the first-placed runner's choice. Depending on the start time of the first loop, either the second and fourth loops are run at night, or the first, third, and fifth loops are run at night. Runners who complete three circuits of the loop (60-miles) are said to have completed a "fun run".

With 54,200 feet (16,500 m) of accumulated vertical climb (and the same amount of descent), the 100-mile run is considered to be one of the most challenging ultramarathons held in the United States, if not the world.[11] As of 2018, about 55% of the races had ended with no finishers.[13][14]

The 100-mile and 60-mile distances are nominal. While a nominal distance of 20 miles, which only covers the horizontal distance, the actual length of the loop varies due to changes in the elevations on the course. Some say the loop is as long as 26 miles (42 km), yielding 130 miles (210 km) for the full race and 78 miles (126 km) for the "fun run."[15][16]"

I love the way they organiser hides books at various points on the course and you must tear out a specific numbered page and bring it back with you to prove you've done the full loop.
