ULTRA May 48 Hour Challenge 

What: Join us for 48 hours of type-two fun!

When: Friday May 27th @ 8pm EDT to Sunday May 29th @ 5pm EDT!

What started as a response to thousands of canceled events during the pandemic has turned into an annual experience. It’s simply part of the Endurance Nation ethos.

We decided to create an event that would give endurance athletes a chance to connect online and boost their fitness. We created a unique format with “relaxed” rules to make this event as accessible as possible to athletes of all abilities. 

The goal here is to challenge your aerobic endurance with micro-doses of training over the course of 48 hours.  We’ll do as much of this “together” as possible using Discord and a Strava group.  By the end of the challenge you will have been active across 24, 36 or 48-hours depending on the level you have chosen. 

Participants will complete an hour of endurance exercise (usually cycling and running) for one hour, every four hours, for their chosen duration.

1 💥: 24-Hour Cycle, 6 hours of training.
Six hours doesn’t sound so bad until you realize you do it in 24 hours starting on Friday night…you’ll be done before the second night, but you’ll be feeling that fatigue for sure. Your choice of sports, but obviously the timing will have to work out (no midnight swimming please!!!).

2 💥💥: 36-Hour Cycle, 9 hours of training.
Nine hours puts you right in the mix of it. Miserable enough you did more than six and close enough to twelve that you might as well do it. Are you kidding those folks are insane! Starting Friday night, you’ll finish early enough on Sunday to make it to church. Or that family outing. Or to sleep all day. 🤣

3 💥💥💥: 48 Hour Cycle, 12 hours of training.
The full monty. The adventure of Friday night training is gone by the second evening…and what’s left isn’t enough to make you forget just how much the sessions on Sunday are hurting your soul. Pacing, nutrition, and rest is key to be able to go the distance. And lots of music. And power napping

Guidelines / Rules

  • Be smart.
  • Don’t sleep through your session.
  • All workouts need to be posted to our Strava ENVEREST group here.


  • All rides will be organized on Zwift.
  • Athletes should add [ULTRAMAY 48h Challenge] to their last name.
  • We will be in Discord during the Bike portions for those of you on Zwift.
  • Post pictures on Strava for each workout…especially those runs!

Event F.A.Q

Are there teams?

No, everyone participates on their own.

Do we have to alternate bike and run?

No, but you need to do a total of 6 x 1 hour bikes and 6 x 1 hour runs.

Do I have to workout on the hour for each four hour block?

No. You have four hours to complete each session. So if there's a 4am run, you have until 8am (the start of the next block) to get the run done. Plan wisely!
