Badwater Ultramarathon


The Badwater Ultramarathon describes itself as "the world's toughest foot race". It is a course starting at below sea level in the Badwater Basin, in California's Death Valley, and ending at an elevation of 8360 feet at Whitney Portal, the trailhead to Mount Whitney. It takes place annually in mid-July, when the weather conditions are most extreme and temperatures can reach. Consequently, very few people—even among ultramarathoners—are capable of finishing this grueling race.

Course

Originally, the run was conceived as being between the lowest and the highest points in the contiguous United States: Badwater, Death Valley and Mt. Whitney's summit . The two are only eighty miles apart on the map, but the land route between the two points is substantially longer,, because of detours around lakebeds and over mountain ranges. Additionally, since the finish-line is from the nearest trailhead, anyone who competes over the race-distance must be capable of a total physical effort of. Due to the two mountain ranges that must be crossed between Badwater and Whitney, the course's cumulative elevation gain exceeds 19,000 feet.
In later years, as the United States Forest Service required summit permits to climb Mt. Whitney, the official course was shortened to end at Whitney Portal. The Badwater-to-Portal course is long, with 13,000 feet of cumulative elevation gain. Forest Service regulations do not allow competitive events in the John Muir Wilderness.

Early history

The hike between Badwater and Mount Whitney was first made in 1969 by Stan Rodefer and Jim Burnworth of San Diego.
Al Arnold first attempted running the route in 1974 but was pulled off the course after eighteen miles with severe dehydration. After vigorous sauna-training and desert-acclimatization, he attempted the run again in 1975. This time, a knee injury aborted the run at fifty miles. In 1976, training injuries kept him from even beginning his annual attempt on the course.
In 1977 he successfully pioneered running the course, summiting Whitney eighty hours after his start at Badwater. Arnold has never returned to the course, except to receive the Badwater Hall of Fame Award.
In 1980, Gary Morris of Marina Del Rey California attempted to beat Arnold's record. When temps hit 120 degrees F, he pulled out and didn't plan to run in 1981. He worked out with Jay Birmingham and Jon Griffin in Marina Del Rey before the attempt, and Jay's run from Los Angeles to New York City.
The second Badwater-to-Whitney running was completed in 1981, by Jay Birmingham.
In 1987, the crossing became an official, organized footrace. Five runners competed the first year. During the early years of the race, no particular route between Badwater and Whitney was specified and runners attempted various "shortcuts" between the start and finish. Adrian Crane, one of the competitors in the inaugural race, even used cross-country skis to cross the salt-flats at Badwater.

AdventureCORPS Badwater Ultramarathon

Currently, manages the competitive race from Badwater to Whitney Portal. The course route is specified, and the race is held annually. The field is invitation-only and limited in size. Demand to participate in the race usually far exceeds available spots. Rules have changed somewhat over the years: afternoon starts have been discontinued; the use of intravenous fluids now disqualifies a runner.
Course support is not provided. Each runner must arrange for his or her own support crew and vehicle. The crew provides their runner with his or her needs, including water, ice, food, gear, pacing, and first aid.
In the past, runners were allowed sixty hours to complete the course, but this has been changed to a 48-hour course limit and a 28 hours cutoff at Panamint Springs Resort. Finishers receive a belt buckle and medal but no prize money is awarded.
The record for the race was set in 1991 by Marshall Ulrich: 33 hours and 54 minutes. Records for the current course are 21 hours 33 minutes 01 seconds, set by Yoshihiko Ishikawa, and 24 hours 13 minutes 24 seconds, set by Patryzja Bereznowska.
In 2002 Pam Reed was the first woman to become the overall winner of the Badwater Ultramarathon. She subsequently repeated as overall winner of the race in 2003. In 2002, her win also set the women's course record at the time.
In the last few years, about 90 people have competed in each race, with 20–40% failing to reach the finish line. There have been no fatalities.
The 2020 edition of the race was cancelled due to the coronavirus pandemic, with all 102 confirmed participants guaranteed entry in 2021.

Multiple crossings

In 1989, Tom Crawford and Richard Benyo completed the first double crossing, running from Badwater to Mount Whitney's summit and back to Badwater again.
In 1994, Scott Weber completed the first Triple Crossing going from the Mount Whitney Summit to Badwater, then returning from Badwater to the Mount Whitney summit, then going from the Mount Whitney summit back to Badwater in 10 days. The first leg of the Triple was also done solo unassisted with Weber pushing an unmodified 'baby jogger' cart with his supplies from oasis to oasis spaced from 20 to apart. Weber completed the majority of the triple unassisted and solo, being met once or twice a day by Ben on the second leg and for of the third leg. Faced with the necessity of completing the Triple before August ended, Weber abandoned his cart at mile 390 to be fully crewed by Denise Jones. Completing this Triple and adding the Badwater race from the previous month made Weber the first runner to complete four full crossings of the Badwater-Mount Whitney summit course in a single July–August window. He remains the only runner to have done a multiple crossing with a solo unassisted section of or greater.
In 2001, Marshall Ulrich was the first runner to complete the "Badwater Quad", consisting of two back-to-back Death Valley 300s for a total of four consecutive Badwater/Whitney transits. He completed the course, a distance in excess of twenty-two marathons, in ten days.
In 2003, Sawyer Manuj became the first Asian-American to complete the Badwater duo.
In 2012, Terry Abrams became the first woman to complete a solo Triple 146 crossing, 438 miles, which includes two summits of Mt. Whitney. She is also the oldest woman to complete the Double, 292 miles.
In 2014, Lisa Smith-Batchen became the first woman to complete the "Badwater Quad", 584 miles in 15 days.

Unassisted solo crossings

In 1994, Scott Weber became the first runner to cross from the summit of Mount Whitney to Badwater course solo without a crew. He did so by pushing a 'baby-jogger' cart with his supplies going oasis to oasis. Weber then continued on to complete 2 additional crossing with minimal support until being crewed full-time for the final of this 438+ mile journey.

Unassisted "self-contained" solo crossings

In July 1999, Marshall Ulrich became the first runner to complete the Badwater-to-Summit course without a crew or resupply, denying himself the use of artificial shade or outside aid of any kind. Starting with of gear and water loaded in a modified baby jogger, he pushed and pulled the cart to the Whitney trail head, then continued on to the summit with a pack. He reached Whitney's summit in seventy seven hours and forty six minutes.
In July 2004, Jeff Sauter became the second person to attempt a solo self-contained crossing under Marshall Ulrich's rules, and completed the 135 mile course to Whitney Portal in 72 hours, but succumbed to hypothermia on the way to the summit and failed to finish the 146 mile course.
Ben "Badwater" Jones, the reference authority and person who documents Badwater crossings, documented the following attempts on his website. . After 2012, the Badwater 146 crossings and guidelines are maintained at
In July 2011, Lisa Bliss became the first woman and second person to complete the 146 mile Badwater-to-Summit course totally self-contained. She pushed and pulled a custom-built 3-wheeled cart filled with water and gear that weighed 240 pounds at the start from Badwater to the Whitney trail head, and then continued the remaining 11 miles to the summit with a pack that she carried from the start. She reached the Mt. Whitney summit in 89 hours and 38 minutes.
On July 14th, 2016, Dusty Hardman became the second woman to complete Badwater 146 in 80 hours and 57 minutes while pushing a modified baby stroller. She pushed the stroller from Badwater Basin to Lone Pine and then carried gear and water to the Whitney Summit from Lone Pine.
In July 2012, "Bogie" Bogdan Dumitrescu made an unsuccessful attempt. In August 2012, Croix Sather got to the Whitney Portal in 64:55 and summited Whitney in 72:55, setting a new record. A subsequent attempt was made by "Bogie" Bogdan Dumitrescu who got to the Whitney Portal in 56:50 and summited Whitney in 70:40. Bogie started on July 8, 2013 at 7:45am, got to the portal at 12:03pm and summited Whitney on 7/10/13 at 20:03 in the evening, setting a new time of 60 hours 18 minutes. In 2014 Bogie started on July 1 and had to stop after Townes Pass due to severe dizziness and breathing problems. But he returned two weeks later, and finished with a time of 57 hours 18 minutes.

Badwater Solo Ultra 135/146

Through the years, runners of all abilities have completed individual Badwater to Mt. Whitney crossings in the spirit of the early crossings, usually aided by crew. In 2005, Hugh Murphy initiated an informal gathering known as the Badwater Solo Ultra 135/146. Runners could finish at Whitney Portal, but were encouraged to continue to the summit of Mt. Whitney Finishers of either distance were presented with a bronze belt buckle. In 2007, the informal group start was dissolved due to National Park Service permitting regulations. Solo runners continue to complete the course on an individual basis during the months of July and August. The word "solo" is used to designate runners who are not part of the official race. These Solos should not be confused with the unassisted crossings of Ulrich or Weber. In compliance with National Park and Forest Service permitting rules, the Badwater Solo is not a competitive race or an organized event of any kind. In general there are three types of recognized "solos". "Solo badwater" where the runner has a crew. "Solo self supported" or "Solo Oasis to oasis", where the runner does not have a crew but can use/buy/stash water and food. "Solo self contained" where the runner cannot get help and has to carry all food and water. Since 2007, Marcia Rasmussen has attempted to award each Solo crossing a buckle for their finish. "Badwater" Ben Jones used to maintain a "Master List" of all Badwater-to-Whitney crossings, including finishers of the official Badwater Ultramarathon and the Badwater Solo. Now all the Badwater 146 crossings are at
In 2007, then 19-year-old Ben Eakin – son of Laura Weber and coached and crewed by Scott Weber – completed his first solo crossing, having only finished 2 marathons and 1 50K prior to doing so. Eakin completed the 146 mile solo from Badwater to the summit of Mount Whitney, to become the youngest person to complete the lowest to highest course, as well as the first type-1 diabetic.
In 2005, Barbara Szeprethy, then 24, is the youngest woman to finish the course, 3 times total, in consecutive years.
