Regular price $65.00

Looking for a great personal challenge? Need to log some big miles to get to your annual mileage goal? Maybe you are thinking about doing an ultra-marathon? Perhaps you just want to prove you are one mentally tough son-of-a-gun? Well then, try on the 4x4x48!

  • What is the 4x4x48?  

4 mile run, every 4 hours for 48 hours.

  • When is the 2018 4x4x48?

Participants must start and complete their 4x4x48 anytime between 12:01 AM October 12th, 2018 and 12:59 PM November 13th, 2018 (Veterans Day).

  • Where does the 4x4x48 take place?

Wherever you are.  The beauty of the 4x4x48 is that you do it where you are and you post your runs to Strava.

  • What does the 4x4x48 cost?

$65, with net proceeds going to Beyond Brave.

  • What do you get for completing the 4x4x48?

You get to tell your friends that you are likely crazier than they are...and all registrants who complete the challenge, following the rules below, will get a Fusion S1 Run Jacket, worth $135..

Rules of 4x4x48

Yes there are rules. Participants have between 112:01 AM October 12th, 2018 and 12:59 PM November 13th, 2018 (Veterans Day) to complete your 48 hour streak. All entries must be GPS uploaded to the 2018 Fusion 4x4x48 to benefit Beyon Brave Strava Club page. No bicycles, skateboards, roller blades...just good old fashioned running. You can start your first "leg" at any time of day but you must start each subsequent "leg" within 4 hours of the time you started the previous leg. For example, if you start at Noon, the next run would be at 4PM, then 8PM, Midnight, 4AM, 8AM...No treadmill runs, you have to get outside and run...elements be damned!  There will be people who ask "can I run all 48 miles at one time?" and the answer is NO.  A big part of the challenge is the nature of having to spread the run out over 48 hours and go every 4 hours over and over again.


Ask a Question
  • Thank you very much for answering my previous questions. There was one unanswered one - if someone wants to donate more than the $65 registration fee, is there a way to do that? And are the donations tax deductible? Thank you.

  • My husband wants to do the challenge and he is a slow runner. Is there a cut-off pace?

    Doesn't matter the speed as long as you go!

    Each leg has to be completed before the next one begins.  That gives a participant 4 hours to finish the 4 mile leg.  If he takes an hour to cover 4 miles then he has three hours of rest.

    Have him sign up.  He will enjoy the challenge.

  • I'm a little confused by the requirements. If I'm always required to start the next leg within 4 hours of the previous leg, I could easily push myself into a far less than 48 hour total. So if my first run is at 8AM, then say I do my second at 11 AM, because that's within 4 hours, now I'm forced to do the next one before 3PM. And let's say I do the same sort of thing a couple more times, where I only wait 2 or 3 hours between legs. Since the requirement is to START the next leg within 4 hours of the previous leg, I could easily finish the mileage before getting to 48 hours.

    You need to start a run every 4 hours.  If it takes you 45 minutes to do the first run then you have 3:15 to rest.  If you start at noon your next run is 4PM, then 8PM, midnight, 4AM, 8AM, noon…

  • Once we upload all of our miles, how do we select the color and size of the jacket?


    Good quesion.  Once a participant has registered they will get an email outlining all the details of the event.

    To answer your specific question, once the event has been completed by a participant they will be sent a link to select there size and hav ti shipped to them.  The color of the jacket is predetermined.  Last year we used flourescent yellow. This year's jacket will be surf blue.

    We hope to have you join us for the 4x4x48.

One and done

I was a fan of the the physical aspect of the 4x4x48 challenge, but not a fan of how this event was run. Over $3K was brought in through registration fees, but less than $1K of that went to Beyond Brave?? Not enough in my opinion. Another issue is timely follow through. It took 4 weeks for the Strava entries to be verified, 3 more weeks to get jacket orders, and now an additional 3 weeks to get them custom printed. It has been 2.5 MONTHS since the challenge ended and we still haven’t received these jackets. Again, that wouldn’t be a big deal, but if that’s where most of our money went, then I’d like to see these jackets! Reasons for the delays were given (company trade shows, people not complying with the Strava guidelines, holidays, etc.), but at some point these reasons just become excuses. I’ve participated in countless road races, triathlons, and other physical events over the years, and have never seen anything quite like this. If I were you, I would cut out the middle man, skip the challenge, and donate directly to Beyond Brave.

Awesome Challenge

Challenge was awesome, can't wait to see the jacket and the pants I ordered.

Nice challenge

I really enjoyed this challenge. It was great to get me off the couch and motivated to run when my season would have otherwise been winding down.
