The Sierra Nevada is the highest mountain range in the contiguous United States.The Sierra Challenge is a series of ten consecutive day hikes to some of the most challenging peaks within the Sierra Nevada. The term day hike is loosely defined here as a wilderness outing that can be completed within 24 hours, starting from and returning to a predetermined trailhead. While the main objective of the wilderness outing is to summit a designated peak, other forms of encouraged outdoor recreation include fishing or simply hiking. The peaks for the 2023 event were chosen based on several criteria: they haven't appeared on previous Sierra Challenges; they hold a special interest to the organizer; they are demanding day hikes, much like the events that preceded it. They average 17.3 miles of hiking/climbing and 6,000 feet of elevation gain. An average day is not unlike climbing Half Dome, but with more off-trail hiking, more technically demanding scrambling, and longer exposure at higher elevations.

The Challenge is open to anyone who wishes to participate, whether for a single day or all ten. This is primarily a wilderness experience, and as such there are serious risks involved that are the responsibility of each individual participant to manage for themselves. There is no water, food, first-aid stations, emergency services or shelter of any kind available to those in trouble. The Sierra Challenge is not a formal organization or event, but rather a haphazardly chosen list of random peaks. Hence, there will be no official support structure available to participants in case of emergencies If you are uncomfortable accepting such risks in any way, you should not participate.


The Peaks

The first Sierra Challenges drew primarily from the Sierra Club's
SPS Peaks List. All of the selected peaks were located on or near the Sierra crest in the High Sierra region, stretching from northern Yosemite to the Golden Trout Wilderness south of Mt. Whitney. For the 2023 event, a new list of ten peaks was selected, none from the SPS list, but all offering a challenging outing in beautiful settings. Most are interesting, unofficially named Sierra Nevada summits that I've come across in my research. For those new, or relatively new to the Challenge, the rules allow you to choose alternative peaks from the previous years that may be of higher interest or less technical risk to you while still keeping you in the running for the coveted jerseys. The peaks selected range from class 2 to class 5 in technical difficulty and should include something of interest for almost any peakbagger. Climbs are rated per the Yosemite Decimal System (YDS). Ratings are purely subjective and can change from year to year depending on conditions. Most climbers require a rope for climbs rated at class 4-5. Ice axes and crampons may be required for some of these outings, noted on the individual pages for the peaks. If the individual peak page does not mention a need for a rope, ice axes or crampons, that does not mean you will not require this additional gear. Many of these peaks are rarely climbed and information regarding them is scarce, meaning the suggested guidance on the individual peak pages may be incorrect. It will be up to the individual climber to evaluate acceptable risks and determine what gear to take.

Why the Challenge?

Good question. I like the challenge of an endurance event, but I'm not so good with the sleep deprivation that goes with some of the other challenges out there such as the California 14er record (set by Sean O'Rourke in just over 62hrs) and the Colorado 14er record (set in 2015 by Andrew Hamilton in just under 10 days).

I figure there is no chance in hell I'm going to come close to either of these guys. I simply must bow down to their superior skills and stamina. I don't have the will to climb for days on end with little sleep, hiking way before sunup and way past sundown. I will leave it to others to chase those dreams...

The Sierra Challenge opens to a wider audience some of the same experiences of these marathon climbing events. I conceived it as a personal challenge that was at the edge of my own abilities, and wanted to share the experience with others who might similarly enjoy a good workout. Besides, suffering is more fun if you have someone to share it with. :)


Who is organizing this?

The Sierra Challenge is being primarily organized by Bob Burd and Sean Casserly. There is no legal entity responsible for this event and no grants available for advertising, promotion, or funding. It is being done on a volunteer basis (in terms of time, money, and energy), so please be kind to the organizers. With families to support, they have limited time and resources.

How do I participate?

Send mail to casserly79@gmail.com. Let me know which peaks you are interested in climbing. I will include you on a mail list for future info about carpooling, meeting times, changes, etc. I would like to collect the following information about you as well so that we can post it on this website. That will allow others to contact you for coordinating hiking, climbing, and driving partners. If you would like information to be kept confidential, please indicate this, and it will not be posted. If you're really worried about privacy, give me as much info as you see fit, your email address being the minimum required amount. You are also free to simply show up at the trailhead and join us, but it is helpful for planning purposes if you can let me know in advance that you intend to join us. Send a photo of yourself (or point me to one on the web) if you'd like your picture shown on your information page. It can prove useful to allow others to identify you at the trailhead or out on the trail.

    You may also choose to climb these peaks following The Rules on days other than those listed here. I will be happy to add your name to the finishers list provided that as a minimum you post a trip report about your adventure. You can post it here (via email), or any other place and simply pass along the URL for me to post on this website.


    What does this cost?

    Nominally, nothing. There are no entrance fees to participate in any of these hikes. You are responsible for your own food, lodging, and gear. There is a nominal charge for T-shirts, but there is no obligation to buy anything from the organizer.

    How am I scored?

    I attempt to track which peaks have been climbed by each participant, and how long they were out on the trail each day. Peaks are categorized as Challenge peaks, Bonus peaks (climbed in addition to the Challenge peak on the same day), or Alternates (Challenge peak not climbed that day). This is compiled on a spreadsheet which is posted online daily during the event. Here's the 2007 stat sheet as an example. Times are measured to the nearest five minutes. All participants are encouraged to aid me in collecting this information (since I won't be at the TH to time your return).

    A new rule was introduced in 2006 as it was acknowledged that the list of peaks grows more obscure each year - any of the previous years' Challenge peaks may also be climbed and count as a Challenge peak providing you haven't already climbed it during a previous Challenge, though it doesn't usually weight as high as the current year's peaks. If you're starting from the same trailhead and the previous Challenge peak is as hard, or harder than this year's, then it will carry equal weight in scoring.

    Scoring is based on the number of Challenge peaks you successfully summit. There is additional credit awarded for climbing "bonus" peaks. Roughly following the model of the Tour de France, there are four jerseys or categories that are tracked throughout the event.

    Yellow Jersey - Overall Leader

    This is the primary category, tracking the number of Challenge peaks climbed throughout the ten days. One point is awarded if a Challenge peak is climbed. The maximum is one point per day. The climber that reaches the most of this year's Challenge Peaks is the winner. If there is a tie, the jersey goes to the climber with the most Challenge Peaks. If there is still a tie, the climber with the least time overall time of the Challenge Peaks in common will be declared the winner.

    Polka Dot Jersey - King of the Mountain

    You are awarded one point for each peak climbed. If a Challenge peak is not climbed that day, a maximum of two points can be awarded (this is to discourage climbing a bunch of easy peaks). There is no maximum number of points that can be awarded if a Challenge peak is climbed in combination. All officially named peaks are eligible ("official" means recognized by the USGS - most, but not all appear on the 7.5' topo map). Unofficially named peaks are eligible if they are named in Secor's book and they have at least 260' of prominence - this rule eliminates a number of the points between Mts. Whitney and Muir, for example. Any summit with at least 500' of prominence is eligible as a bonus peak whether named or not. Any summit over 9,000ft with at least 260' of prominence will be eligible as a bonus peak whether named or not.

    White Jersey - Best Young Climber (under 25yrs)

    This award goes to the young climber completing the most Challenge peaks. Scoring is identical to the yellow jersey.

    Green Jersey - Best Masters Climber (over 50yrs)

    This award goes to the older climber completing the most Challenge peaks. Scoring is identical to the yellow jersey.

    In the event of a tie in any category, the participant with the most peaks from this year's list will be the winner. A previous Challenge peak starting from the same trailhead that is the same or harder in terms of difficulty will be deemed equal to this year's Challenge peak. As has happened at least once, the Yellow Jersey winner may not have climbed all of this year's Challenge peaks. The event organizer is the sole arbiter as to which summit is more challenging. You can ask ahead of time if it's not obvious to you before starting out. If a tie still exists, the total time on the trail is used to determine the leader. Only total time for peaks from this year's list will be used in the determination (it would be unfair to compare times for say The Hermit and University Peak, for example).

    Red Number - Most Aggressive Route

    This award derives from the Super Combativity award given during the Tour de France. The red number is a subjective award that will be given to the most aggressive route. Technical difficulty, length, creativity and aesthetic nature will all be taken into account.

    There is also the daily Stage Winner, the person who gets to the day's Challenge peak and back in the fastest time. No extra credit for bonus peaks here. If you can't win a jersey, you might at least take home a Stage Win. Or two.

    All scoring decisions are made by the event organizer and should be considered final unless I change my mind. This does not mean that decisions cannot be influenced by participants. Scoring rules are always subject to change.


    What are the prizes?

    There are no prizes. It is hoped that the enjoyment of participation is enough of a reward. There will be recognition on this website for all participants and finishers. If you were hoping for something more in the way of remuneration, please look elsewhere.

    What am I in for?

    Most of these peaks are usually climbed as multi-day trips. As day hikes these climbs are all very strenuous. You should not attempt any of them without proper training and experience. Only you can judge your level of preparedness, so no training formula can be given that works for everyone. There are those that train for months and still fail to summit Mt. Whitney even though a regular trail exists all the way to the top. There are others who because of outstanding physiology or possibly sheer will might not train at all and still go out and climb the toughest of these. I would expect that those with the best chances to succeed will have experience with long hikes combined with much elevation gain ( 20+ miles, 5000+ ft), extensive cross-country travel, and are comfortable climbing class 3 rock, snow, and ice.

    You should not expect others to lead you to the summit or wait for you along the way. No one has yet started out running on any of the previous Challenges, but the pace in the front is brisk, around 3mph on the uphills. A fast pace allows participants to reach the summit before afternoon thunderstorms may appear, as well as to get off the trail to start resting for the next day as early as possible. You should carry a map and whatever other gear you deem appropriate to be self-sufficient, and be familiar with the route (study it beforehand, and know how to read your map) in case you find yourself alone because others didn't wait for you. That said, it is primarily a social experience. We would rather hike as a group, climb to the summit together and return to town to eat and drink together while reliving the day's adventure. If you aren't going to keep up, it's usually clear in the first hour or so. If the technical difficulty is more than you're comfortable with, don't be afraid to speak up for some additional guidance, or to turn back and call it a day. Participants regularly turn back before reaching the summit but still enjoy a great adventure in the mountains. There have been days where no one reaches the summit of the challenge peak.


    Who do I sue if I get hurt?

    No one. There is no official organization to ensure any level of safety any greater than you have on your own when you venture into the Wilderness. If you are hiking or climbing with others during this event, you do so the same as if you were out with friends. Don't expect anyone to ensure the qualifications of another you are hiking or climbing with. If you have doubts, you should find someone you trust, go alone, or choose not to participate.
