vEveresting: An Objective Review

May 28, 2025

LAST UPDATED May 27, 2025

I vEverested on Friday, May 23rd. While preparing, I consulted various resources, including the Zwift Insider posts from Ron Chatfield and Tim Perkin. These testimonials helped me understand what I was facing, and now that I’ve completed the challenge, I want to share my experience with the community to help others prepare for their epic vEverestings.

Getting Started

After a few weeks of consideration, I scheduled the ride for Friday, May 23rd. Leading up to the day, I secured my nutrition and configured my pain cave/battle station for the event, trying not to overthink the challenge ahead.

I didn’t adjust my training schedule in advance of the attempt and still raced with my TTT team the day before the event (go CRYO-GEN Kestrels). Early Friday morning, I set out. Here are my observations.

Initial Preparation

I’m a data nerd. As such, I was at home researching and planning my vEverest attempt. I consulted first-hand reports, compared segment data, and quickly decided to use Road to Sky and Alpe du Zwift for the ride. After running the numbers through Everesting’s lap calculator, I settled on a 12-hour target time. I prefer to train early in the morning, but your chronotype will ultimately determine your optimal ride schedule. I scheduled my attempt for 4 am, intending to have an early dinner.

The Day Before

I assembled my nutrition and set up an extra table next to my trainer to house the goods. I completed a full video weigh-in, updated my weight in Zwift, set the trainer difficulty to 100% according to Everesting rules, and took screenshots and photos of each step in Zwift’s settings.

This is a good time to optimize your virtual gears, as trainer difficulty will change the feel of the ascents. Also, hit the garage and equip your fastest climbing bike and wheels! I used the S-Works Aethos and Zipp 353 NSW wheels.

The Day Of

I woke up an hour early, but otherwise maintained my routine. Wake, dress, eat, stretch, and train. After logging on and taking a few more pictures, I started out, quickly realizing I needed to adjust my gearing further. After that hiccup, I started my watch and was off at 4:17 am. My pace for ascents one through three was hot and likely unsustainable. This was entirely avoidable, but I settled into a sustainable pace by lap four, which I maintained until lap nine.

I utilized each descent to get off the bike, eat real food, refill hydration, change kit, and bio break. Use these rests wisely, but do not let your guard down. I avoided sitting down and used the time strictly to prepare for the next ascent. Time your first descent so you can return to the bike before your avatar passes the segment start line. Be aware of the limitations of your watch and heart rate monitor as you leave your training area. Consider leaving them behind to prevent disconnects from your trainer and Zwift device.

After completing the vEveresting, I straightened up my pain cave and headed for the shower. I consistently fueled during the ride and wasn’t hungry, but I happily ate a massive burrito, then retired to the couch with my laptop to pore over my data.

The Next Day

I returned to my usual routine: wake, dress, eat, stretch, and train. The legs felt okay, all things considered, and 90 minutes of zone 1 got things loosened up. My only other activity for the day was resting, eating, and walking after meals. While not fully recovered, by the end of the day, I was ready to lead my Sunday morning 2-hour Cat C group ride (go Team CRYO-GEN).

Environment

Optimizing your environment will help you be more efficient and comfortable for such a long session on a trainer. Familiarize yourself with your training area so you know what time to close the shades and block the afternoon sun. Make a reminder to adjust the HVAC to prevent the space from becoming too hot or humid. Adjust the lighting to prevent glare, darkness, or other distracting conditions. Check the condition of your fans and add more if needed. Stock your training area with clean towels and sweatbands.

Nutrition

This will make or break your ride. Stick with familiar foods that you’re comfortable with and do not cause you digestive or GI issues. Fuel early and often. Set up a dedicated table for on-bike nutrition where everything is easily accessible. The goal is to reduce friction and encourage fueling, as you may not feel like eating. Supplement your water with electrolytes and hydrate consistently throughout the session. As with food, stick with known brands that do not cause you issues. Consider pre-hydrating with electrolytes before you begin your attempt.

Hardware

Some tips to ensure your hardware functions smoothly throughout your vEverest attempt:

Update your Zwift devices, head units, watches, and tech well in advance of your vEverest attempt.
Allow plenty of time to establish a secure connection between your trainer, Zwift device, head unit, watch, and heart rate monitor. Make a test ride or two prior to starting your attempt to ensure that all devices are communicating with reliable connections.
Address any bike, trainer, rocker plate, or shoe maintenance well ahead of your ride.
Dial in your physical or virtual gears before your attempt. The 100% trainer difficulty setting will impact the feel of the ascent. Get comfortable with your updated gearing before you set out.
Set up a charger for your phone and wireless headphones.
If running Zwift on a tablet or phone, ensure your charger is powerful enough to charge the device while it is running Zwift.

Zwift Features

Zwift launched the new lap feature the week of my vEveresting. The lap counter was an outstanding tool, and I was able to launch a new lap at the start of each ascent. Initially, I planned to reset the lap counter at the beginning and end of each ascent, but I quickly forgot to reset it at the top of the mountain and decided to log each complete lap instead. Combined with the segment timer HUD elements, the lap counter made it easy to compare average power, heart rate, and time.

vEveresting also provided an outstanding opportunity to upgrade my S-Works Aethos climbing bike. Ahead of the ride, I noted the elevation thresholds for each upgrade level and used them as milestones during the session. When I hit an upgrade, I quickly stopped, hit the drop shop, and purchased the upgrade. This routine was motivational, and I was able to upgrade from level 0 to level 3 by lap 8!

The HoloReplay ghost is the MVP of a ride with repeating segments. Once you’ve established a sustainable pace, your ghost will escort you up the mountain on the next lap. If you pace yourself to the ghost, you can hit consistent lap times with little effort. Be aware of chasing a fast ghost and know when to fold and let the ghost ride ahead. The sunk cost fallacy is real, and it’s easy to attempt to maintain the unsustainable pace from your previous lap.

Kit

Bib selection is paramount for a ride this long. Use your best-fitting, most comfortable bibs, and plan to swap them at least once during the ride. I changed my bibs, shirt, and socks after lap four and felt like a new person. Consider swapping to a different model or style of bibs when you change. A slightly different fit may help prevent hot spots caused by impedance mismatches between your bibs and anatomy.

Training

A strong level of base fitness is necessary for vEveresting. Consider long ERG mode training sessions in zones 2 and 3. There is no coasting up the mountain, and if you stop or slow pedaling, you will stop moving. ERG mode helps train you to maintain steady and consistent power, which is crucial for this attempt.

Pets

Ensure you have a feeding, walking, and care plan in place for your pets. Make sure that they are comfortable while you suffer on your ride.

Support

While it’s more challenging to take on this attempt unsupported, it’s entirely possible. If possible, schedule your ride for a day when family or friends are available to assist. I rode unsupported until the very end when my beautiful wife brought home burritos. Consider coordinating with your Zwift team, who will provide moral support during your ride. I kept my attempt a secret until one of my teammates noticed me online with 200 km clocked and rallied the team for an all-out ride-on assault. This gesture helped me in the end.

Conclusion

vEveresting was the hardest thing I’ve done on a bike, indoors or out. It put my endurance to the test but resulted in a deep feeling of accomplishment that I’m sure won’t come from anywhere else. A massive thank you to the community for the content that helped me plan the event and Team CRYO-GEN for motivation and props. Hopefully, this article will help others in the future. Be well and ride on!
