Eventbrite - 2018 Checkpoint Challenge

Grab your partners and head out to collect checkpoints on a kayaking, mountain biking, and trekking challenge, condensing a month’s worth of adventure into a short expedition through California’s beautiful backcountry. See some beautiful country and make lifetime memories!

“Teamwork was very important: when we worked as a team, we could achieve so much more than we could alone.”

Checkpoint ChallengeThe Checkpoint Challenge partner race


  • 8-10 miles of mountain biking (60% single track, not technical, but if you’re used to sticking to fire roads, this will be challenging)
  • 4 miles of technical trail running/scrambling/swimming (minimal swimming skills needed – if you can handle a pool, you’ll handle this)
  • 2-3 miles of kayaking
  • This is a great way to get introduced to traditional adventure racing! You’ll experience the partner aspect while enjoying minimally marked courses that require you to follow your map.

Doing the half day?

Double the trek and kayak distances, add orienteering and epic ropes! You will be on less marked course and need to  rely on a map and compass to complete the course.

Checkpoint ChallengeExperience Needed

The Checkpoint Challenge is designed to challenge the elite athlete but remain achievable for the novice off the couch participant. As with most things, the more prepared you are the better your experience will be. Before starting any training program consult a medical professional about potential risks involved.

We recommend biking, running and kayaking as ways to prepare for this race.

You do not need a support team for this race – it is designed to be self-supporting. Details will be sent out in our pre-race email sent a week before the event.

“So proud that our team worked so well together. I was worried my partner and I would argue, but I reminded him that when we race, NOTHING gets in the way of the finish line!”


We understand you’re putting your life in our hands for the time you’re on the course and we want you to know what’s on deck should you need it:

  • We work with the local Search and Rescue team to provide EMTs and rescue equipment on course throughout the whole event.
  • We also have arrangements with CalStar, an air ambulance, and H70, the local CHP rescue helicopter for ALS and hard to reach locations.
  • On the water we have a patrol boat for kayak and boat safety.

The worst injury we have had in our 9 years was heat stroke and we had an IV in him in 10 minutes en route to the local ER in 20 minutes.

All of our transition areas and course marshals have VHF radios that use a repeater so we have communications throughout the entire course, as little to no cell phone reception is available in some of the areas we travel through.

Eventbrite - 2018 Checkpoint Challenge



Adventure Race: Family FriendlyAdventure racing is often thought of as an epic, brutal day of suffering, but it doesn’t have to be. This is most true for the rare, but beloved, Checkpoint Challenge.

AR has traditionally called this division a “sprint” but we felt the name was misleading. Therefore, we call it the Checkpoint Challenge because sprinting is entirely optional but the checkpoint gathering isn’t!

Partner Racers will experience 3-5 hours of kayaking, trekking (at this distance, many do run, but many do not) through fields, up rocks, and on trails, and mountain biking beginner trails (some fire road, but yes, some single track), along with some fun team challenges in pursuit of filling their passcodes with the right punches.

Half day racers will experience 6+ hours of the same, but with challenges coming to you in the form of rope skills and navigation.

So how fit should you be and how do you get fit to begin with?

First, the skills you need to acquire:


  • Kayaking – if you have never kayaked before, it’s a good idea to rent a tandem kayak with your partner and give it a try before the race; there is absolutely technique involved, but don’t feel like you need to be a champion here – at this level, kayaking is often everyone’s weakness, especially with the provided sit-on top boats.  And, luckily, there’s a great video on  YouTube showing you excellent technique if you’re interested.
  • Mountain biking – this is a must-learn. If you’re comfortable tooling around town or on a road bike for distance, you have that main components down. We do NOT suggest you attempt this race on anything other than a proper mountain bike (fat, knobby tires). Some people go into the race with very low mountain bike skills and complete the course, but you’ll really want to give some single track riding a try, and there are some decent hills on course – you can of course get off and walk up and down them, but it’s nicer if you can enjoy the trails – we put you on fun ones!
  • checkpoint challenge: trail hikingTrekking – you’ll cover quite a bit on foot during the race, and this includes off-trail ascents, a little scrambling, and trails. Get some good hikes in and make sure you challenge yourself. A little skill in climbing up boulders is beneficial, as well, but not necessary.
  • Orienteering skills – the sprint race is designed as an entry into multi-sport adventure racing; the partner course will be marked and no orienteering is required(this is NOT true for the half-day).  Just pay attention to course markings and have a general ability to read maps and you should be fine – we haven’t lost anyone yet in almost a decade of sprint adventure races! Doing the half day? Just follow a team that know what they are doing. Navigation shouldn’t be too challenging, but you can get lost if you don’t practice map and compass skills prior.
  • Special skills – Partner race?  these are accessible to everyone. Don’t stress this in the least- it’s just a puzzle that’s fun to solve with your partner! Half day? We have professionals checking your gear on rope segments, but you should come with a basic understanding of how to use it. If it’s your first time on what we’re throwing at you, relax. We’re professionals.

Now to the question of how fit you should be?

  • At a minimum, you should comfortably be able to paddle a mile – some upper body strength is required. If you aren’t able to kayak, any reasonably fit person who fits the rest of our fitness gauges will probably have little to no issue on the kayaks.
  • Biking – be comfortable biking fast for 15 miles on flat terrain at the very least. This is not flat, but you will not need to be fast. You will need to be comfortable.
  • Trekking – get some good five mile hikes in, with an elevation of at least 1000 feet per hike, this can be rolling. It won’t hurt to do a little bouldering outdoors or at your local gym, but not necessary.

If you’ve never put all these disciplines together, that’s okay – on race day, you’ll pull out all the stops. That’s why the range is two to four hours: fit individuals with experience will finish in two, while the slowest individuals will finish in four. How much work you put in prior to race day determines your finish time – but it won’t determine your ability to come out and really have a grand morning adventure with us!
