The Challenge isn’t just a list of race distances: it’s a pathway to total transformation. Whether you're chasing your first 5K or eyeing the brutal beauty of the full distance triathlon, each milestone is a step deeper into who you can be.

It doesn’t matter if you walk, run, or roll through each race. You can do this.

The Sendō Challenge exists as a middle path in modern fitness: ambitious, long-term training goals that are grounded in daily consistency. You train, you show up, you learn who you are under pressure. Then you keep going.

• Complete the distances in any order
• No time limits
• Official, timed races only
• You don’t have to race fast — you just have to finish
• Life happens. Pauses are allowed but quitting isn’t encouraged

I grew up loving videogames, especially Pokemon, and a list of sequential training goals felt like a good thing that I could fixate on in real life. Not just living through a screen but putting in meaningful work to become physically and mentally stronger.

I've been kicking around variations of this idea for years as I tried to motivate myself to get out of the house. Instead I mostly distracted myself with endless entertainment.

It's been over 900 days since I wrote the first post on this website. It's been a private blog for most of that time but I've been chipping away at a lifetime of bad habits through daily training. I'm still a lazy bum but at least now I've got a good purpose in life outside of work and societal obligations.

I've found that these goals helped me move forward, even if just a little bit. I think they can help you too. That strength, in turn, can help others. That's the real "Sendō Worldwide".

I'll finish The Challenge. You'll do it faster and better. So if you're looking for somewhere to start, something to believe in, anything to try: give this a shot.

See you in the Hall Of Fame.

I’m not just telling you about this manic list of demands: I’m doing it too.

It's dangerous to go alone: take this collection of free training programs, tools and other resources that we've developed over the years.

We’re not here to replace your local run club: we want to support it. Join the Sendō Run Club on Strava to plug into the global club, then run wherever you are, however you want:

• Join the Sendō Run Club for monthly challenges and shared momentum.
• Run with an existing club, start one with friends, build a small crew, or go solo.
• We provide training programs, tools, educational resources, and The Challenge. You build the local culture.

Think of Sendō as the connective layer: many cities, many crews, one shared mission. If you want accountability, motivation, and a bigger story to run inside of, you’re in the right place.

Partnered Races are independently organized running, cycling, and triathlon events that we recognize as valid milestones within the Sendō Challenge. We don’t host or manage races. Instead, we guide you toward established events that meet the distance and spirit of The Challenge. You register directly with the race organizer, train on your own terms, and use the race as a real-world proving ground for the work you’ve put in.

Each name in the Sendō Hall of Fame represents miles moved, challenges overcome, and a commitment to the long road of self-improvement.

Hall of Fame Honors

Every inductee receives:

• Your name (initials or pseudonym) and race results added to the Hall of Fame
• A profile page with your full journey, highlights, photos, and race stats. We'd love to interview you to tell your story.
• A custom-forged Sendō Challenge Master Medal in a beautiful case
• A special-edition Sendō Challenge tee and hoodie

How Do You Get In?

To be inducted, you must:

• Finish all eight Challenge race distances, officially timed and verified. There is no deadline to complete the Sendō Challenge.
• We only accept results from sanctioned races. Apologies if you've PR'd at your friend's backyard ultra but there's too many folks getting sneaky on Strava.
• You can submit your results via Strava links or exports from your training watch (e.g. Garmin, Coros, G-Shock). Whatever format makes sense for you.

If you like what we’re building, you can support Sendō as a Patron (individuals) or Sponsor (organizations). Your support pays for training resources, entertainment and community for people around the world.

Your name and any information is included in every issue of GTD we send out, here on the Sendō website and in the credits of videos we release.
