50 Years Old and 400 Pounds: Charles Givens’ Wake Up Call

50 Years Old and 400 Pounds: Charles Givens’ Wake Up Call

In the world of competitive cycling, there is a certain image that often comes to mind: lean, wiry athletes in skin-tight kits, weighing about as much as a light breeze. But if you find yourself lining up for a crit in the Midwest or jumping into a high-intensity race in Crit City on Zwift, you might encounter a different kind of powerhouse.

Meet Charles Givens—a self-described diesel, a grandfather, and a man whose journey from 400 pounds to the heat of the peloton is nothing short of legendary.

Awakened By a Broken Ankle

For thirty years, Charles lived the life of a dedicated IT dude in Springfield, Missouri. Like many in the industry, the sedentary nature of the job, combined with the stresses of raising two kids, saw his weight steadily climb. Despite being an active gym rat who spent years playing indoor soccer, Charles was always a big guy. By the time he was approaching his 50th birthday, that big guy persona had reached critical mass: he weighed over 400 pounds.

The turning point didn’t come from a doctor’s office or a New Year’s resolution. It came from a set of stairs. In 2010, just as he was turning 50, Charles fell down the steps and broke his ankle. “It didn’t heal right,” Charles recalls. “I knew I had to get this weight off”.

That injury was an awakening. He realized that if he didn’t make a radical change, the next decade of his life would be defined by limited mobility and declining health. He had ridden bikes a bit in the early 2000s, but it was time to take it seriously.

The 20 mph Benchmark

The initial weight loss was a grind, but Charles found that he actually enjoyed the time spent on two wheels. A few years into his journey, around age 52 or 53, he decided to test his mettle. He wasn’t just riding for leisure anymore; being a competitive guy, he wanted to see if he could compete.

He signed up for his first time trial. He set a goal of averaging 20 mph. If he could maintain that average speed in the TT, he would try racing the following year.

Boom! He hit the mark.

Getting “Blown Up” and Loving It

True to his word, Charles entered his first Criterium the following season. At the time, he had dropped down to 250 pounds—an incredible feat, yet still far from a typical racer’s weight.

The race was another wake-up call. “I got my butt kicked,” Charles admits with a laugh. He got blown up early, unable to maintain the blistering pace of the pack. But instead of being discouraged, he was hooked. He loved the intensity, the tactics, and the sheer adrenaline of the sport. He realized that to truly compete, he needed to take his training—and his weight loss—to the next level.

The Zwift Era Begins

One of the catalysts for Charles’ transformation was the Hotter’N Hell Hundred ride in Texas. There, he met a coach who helped guide him through the winter months. The coach introduced him to a platform that would change his life: Zwift.

Charles joined the Zwift community in 2017. It was the perfect match for his gym rat mentality. He could do structured workouts, join a racing team, and compete at any time of day, regardless of the Missouri weather.

Weight Loss Milestones

With the help of his coach and the data-driven environment of Zwift, Charles began ratcheting it up. He realized he was still taking in too many calories for his activity level, so he tightened his nutrition and leaned into the Zwift workouts.

The results were staggering:

  • Starting Weight: 400+ lbs
  • First Crit Weight: 250 lbs
  • Summer Racing Weight: 215 lbs
  • Lowest Weight: 195 lbs

By age 61, Charles was a different man. He was finishing in the top 15 of regional races in fields of 50 riders. He had earned his Cat 4 racing license and was proving that big guys could do more than just hold a wheel—they could lead the pack.

Training as a Diesel

Charles embraces his identity as a big guy cyclist. “I am not your typical racer, think a little bigger,” he says. “210 pounds is a great weight for me, so if I bump you it might hurt… LOL.”

His training setup is built for a diesel powerhouse. He uses a Saris platform to add motion to his indoor rides, making the experience more realistic and engaging. His philosophy is simple: you get out of Zwift what you put into it.

His routine is grueling:

  • IRL Cycling: Dawn Patrol – Every Wednesday and Friday at 5:30 AM, Charles joins a group of about 40 riders for high-intensity training.
  • Gym Work: He maintains his gym rat roots, adjusting his lifting schedule around his rides.
  • Zwift Racing: He spends 3-4 days a week on the platform, even in the summer, with a particular love for the fast-paced action of Crit City.

In races, Charles plays to his strengths. He knows he’s not a mountain climber, but on the flats and through the technical corners, he’s a force to be reckoned with. He works on closing gaps, navigating the wind, and shooting the pocket in the final corners.

The Reset and the 2026 Comeback

Life, as it often does, threw a few more hurdles in Charles’ path. Last year, he was forced to take a break due to a combination of “bad signals”—a crash, equipment failures, and significant medical issues.

But the spirit that took him from 400 pounds to a competitive racer didn’t stay down for long. Now at age 61 (and looking toward the 2026 season), Charles is in the middle of a reset. He is getting his body back in shape, targeting a return to racing in June. “I have had many challenges along the way and still do, but love to ride,” Charles says. “The last year I have just been riding with no real purpose except points and levels. In the next week or so, I will be starting my workouts again”.

Racing For the Moment

When asked about his best feeling on a bike, Charles doesn’t talk about the scale or the power meter. He talks about the moment.

For him, it’s the sensation of hitting a corner while racing, laying the bike down with competitors right on his hip, and hearing the crowd cheer them on. It’s a feeling of pure, unadulterated life—a feeling that was nearly lost on those stairs in 2010.

Thanks, Charles, for sharing your story. Maybe we’ll bump into each other one day… hopefully not in an IRL crit, though! Ride on.

JetBlack Victory Adds USB Connection Support

JetBlack Victory Adds USB Connection Support

Today, JetBlack announced (and Zwift enabled) a new feature on their flagship Victory trainer: a wired USB connection to Zwift.

Updating Your Trainer’s Firmware

To enable data transfer via the Victory’s USB-C port, you’ll need to be running firmware version 4.28 or later. To update your trainer’s firmware, open the JetBlack app, connect to your trainer (it will do this automatically if you’ve done it in the past), then go to Settings>Firmware update. The actual updating process from there is quite simple, and takes 1-2 minutes:

Connecting To Zwift Via USB

Once your firmware is updated, you’ll need to connect the trainer to your Mac or PC using a longish USB-C cable. Zwift recommends a USB 2.0 cable over the newer 3.0 or 3.1 standard, as there’s less signal loss over 2.0. It’ll need to have a USB-C connector on one end (to plug into the Victory), while the other end will need to have whatever connector is supported by your PC or Mac. Here’s a 10-foot USB 2.0 cable from Belkin with USB-C on one end and USB-A on the other.

Once the trainer is connected to your PC or Mac via a USB cable, that connection option should show up in Zwift as the default recommended connection method:

Depending on your computer’s capabilities, if you click “All” you’ll see that the trainer can connect via WiFi, Bluetooth, ANT+, or USB. Zwift automatically sorts the available connection methods in order of reliability:

Click/Play Bridged Connections

The JetBlack Victory and Wahoo KICKR CORE 2 both let you use your trainer as a Bluetooth “bridge” for your heart rate monitor and Zwift Play or Click controllers, which reduces the number of Bluetooth connections your Zwift device (PC, tablet, Apple TV, etc) has to juggle.

While the trainer bridging feature has been available for months now, it’s worth noting it again here, as the bridged data flows through whatever trainer connection method you choose. In certain situations, you may improve connection quality by using this bridging feature rather than pairing your HRM or controllers directly to your Zwift device.

Make sure you update your Zwift Click/Play firmware using the Companion app to ensure maximum reliability:

Questions or comments?

While wiring your trainer will be unnecessary for most Zwifters, the stability of a USB connection will appeal to some. If you’re in a “noisy” environment, struggling with WiFi, Bluetooth, or ANT connection drops, this may be the setup for you. (And at just $399US, the JetBlack Victory is an unmatched value in today’s trainer marketplace.)

Will you be giving USB a try on your JetBlack trainer? Would you like to see this option on other trainers? Share your thoughts below!

SISU Racing Launches the SISU World Cup Beginning June 9

SISU Racing Launches the SISU World Cup Beginning June 9

The world will come together for football’s greatest spectacle this year — and now the world of cycling esports has its own global showdown: the first-ever SISU World Cup.

Inspired by the spirit, passion, and national pride of the FIFA World Cup, SISU Racing has announced a brand-new international racing concept where every pedal stroke counts for your country. Riders won’t just race for individual glory — they’ll race for national pride across four action-packed “Games”. It’s a unique twist, with the fastest three riders in each game counting towards their country’s GC.

United Kingdom Riders – to race for your country, please change the country listed on your profile in the Companion app from the United Kingdom to England, Scotland, Wales, or Northern Ireland.

The Games

And in true SISU fashion, the routes have been selected to test every type of rider — punchers, climbers, diesel engines, technical racers, and tactical masterminds.

Game 1

Tuesday, June 9: Cobbles Crown – Richmond

The SISU World Game begins on the punchy cobbles of Richmond. Short climbs, rolling terrain, and technical rhythm changes will demand explosive power and sharp race IQ. Positioning will be everything as nations battle for the first jersey and first bragging rights of the series.

Game 2

Tuesday, June 16: 2018 UCI Worlds Short Lap – Innsbruck

A nod to one of cycling’s most iconic World Championship venues. Innsbruck delivers relentless climbing pressure and rewards riders who can suffer deep and keep pushing. Pure climbers and punchy all-rounders will smell opportunity here.

Game 3

Tuesday, June 23: Spinfinity – New York

Fast. Aggressive. Unpredictable. New York’s futuristic roads bring high-speed racing with constant elevation changes and no room to hide. Expect attacks, counterattacks, and nations fighting desperately for every second as the SISU World Game reaches its critical phase.

Game 4

Tuesday, June 30: Green to Screen – New York

The final Game promises fireworks. Green to Screen is one of Zwift’s most demanding modern routes — beginning with fast-flowing terrain before rising into a brutal uphill finale. This is where legends will be made, GC battles settled, and one nation crowned champion of the SISU World Game.

The Challenge features four iconic French climbs, listed in the order riders will encounter them in the IRL L’Etape du Tour event held on the Queen Stage (stage 20) of this year’s Tour de France.

You can complete them in any order you’d like, though, or even join a group for extra motivation! Here’s the list, along with dates group rides will be held on each climb:

  • Climb 1: Col de la Croix de Fer
    • Length: 27.1 km (16.8 miles)
    • Elevation Gain: 1558 m (5,112‘)
    • Scheduled events: June 6/7
  • Climb 2: Col du Télégraphe
    • Length: 11.9 km (7.4 miles)

Click that challenge card to access the climbs and see reward details.

Pro tip: Want to double up on bonus XP? Tackle one of the new Quickfire 30 Challenge workouts on a weekend in June when one of the climbs above is scheduled (see June portal schedule). To do this, you’ll need to pick the workout first, from your homescreen. Then choose any route in Watopia (Volcano Circuit CCW is a good one, as it gets you close to the climb portal). You’ll get credit for completing the workout as well as the climb!

Challenge Rewards

You will earn an XP bonus for each climb you complete in the challenge, with a total of 2250 XP available. You will also unlock the L’Etape 2026 Kit if you complete all 4 climbs!

  • 1 climb: 500 XP

Deadline

This challenge goes live on June 1, 2026 at 09:00 PT, and ends July 5, 2026 at 23:59 PT.

(I recommend finishing before the final day, though, as some past Challenges have ended earlier than expected, and you don’t want to be caught out if that happens.)

VO2sday Micro Races, Week 5: 5×4-Minute Mass Start Time Trials in NYC

VO2sday Micro Races, Week 5: 5×4-Minute Mass Start Time Trials in NYC

For the fifth week of our new VO2sday race series, we’re heading to New York for five tough, back-to-back races. Everything this week is the same as last week, except we’re on new roads. Read on for details!

June 2 Race Details and Signup

Here are this week’s courses:

Races are held at three different times each Tuesday:

  • Zone 1: 11am UTC/7am UT/4am PT
  • Zone 2: 5pm UTC/1pm ET/10am PT
  • Zone 3: 11pm UTC/7pm ET/4pm PT

Sign up at zwift.com/events/tag/vo2sday >

Time-Based Races

Until we decide to change it, all VO2sday events will be 4 minutes long, regardless of your category or how hard you ride. The goal? Ride further than your competitors by holding the highest steady power you can muster across all 5 events.

Important note: Because these are time-based races, the only meaningful race results you’ll see this week are on the finishing screen that pops up at the end of each race, and the race results in Companion or at zwift.com. ZwiftPower will not display results properly.

(We won’t have a 5-race GC competition this week, because we don’t have a way to combine rider distances from each race and show them on a leaderboard since ZwiftPower doesn’t support this. Additionally, Zwift has a hard time handling races under 5 minutes in length, so that’s making a GC even more challenging. The good news is, I’m working with Nathan Guerra and his brilliant team over at Leadout Sports to make it happen. Stay tuned for news on this front!)

Compound Score Categories

Race categories are based on Zwift’s Compound Score, which factors in your 5-minute power and bodyweight. Compound Score categories for these events are set to:

  • A: 1600+
  • B: 1200-1600
  • C: 900-1200
  • D: 900 and below

Structured Workout Racing

The VO2sday Micro Races are nothing like your typical Zwift scratch race. Here’s how these races are distinctly structured to be engaging and fun while delivering a proper VO2 max session:

  • 5 races in less than an hour – that’s 5 hard VO2 max intervals.
  • Very short efforts: Each race is very short, only 4 minutes, just like a good VO2 max interval.
  • Recovery time: Races are 10 minutes apart, so a 4-minute race leaves you with 6 minutes of recovery before the next interval.
  • Mix of courses: Each week’s race courses feature a mix of flat, climb, rolling, and even downhill parcours. Riders with lots of pure watts have the advantage in some races, while riders with strong w/kg have the advantage in others.
  • Compound Score categories: Since results will be driven by your power numbers, riders will be categorized based on compound score, not Zwift Racing Score. This takes into account your 5-minute power and body weight.
  • Mass start: While riders are broken into categories for results, these are mass-start events with all categories starting together, so everyone has riders ahead to chase. (Remember, the goal is to push as hard as you can for the duration of the race, not to sit in the pack and conserve so you can sprint to victory in the last 15 seconds!)
  • Drafting is disabled, so these are effectively time trials. (Yes, you’ll want a fast TT setup.) Hopefully this forces you out of the “sit in then sprint” mindset, and into “hold steady high power for the duration” mode.

Questions or comments?

I’d love to hear your feedback after you’ve completed the latest set of VO2sday races. Share it below, along with any questions or comments you’ve got beforehand!


Between Efforts, Episode 2: What Makes Zwift Good, Frustrating, and Still Worth Riding?

Between Efforts, Episode 2: What Makes Zwift Good, Frustrating, and Still Worth Riding?

In this episode of Between Efforts, I talk with Eric Schlange, the founder of Zwift Insider, about the platform, the community and the future of virtual cycling.

We dig into how Zwift Insider grew from a useful side project into the most trusted resource in the Zwift world, what it takes to keep up with constant platform changes, and where Zwift might be heading in 2026 and beyond.

We also talk about racing, the Rouvy acquisition, MyWhoosh, AI summaries affecting creators, Zwift Community Live in Mallorca, and why virtual cycling has become much more than just riding indoors.

✅ Fast Miles ✅ Upgrade Hack ✅ Unique Event 

Want to accumulate lots of miles quickly? Join this popular group ride, which puts everyone on the fastest TT bike in game (Cadex Tri with DT Swiss disc wheels) with drafting enabled. It’s 100km, but it’ll be a fast 100km!

Riders are on Tempus Fugit – the flattest route on Zwift! Four different pace groups are offered, released so the faster groups catch the slower groups over time.

Bike upgrading hack: on rides with forced bikes, whatever bike you’re on when you join the event is the bike that accumulates the distance/elevation/time. So, for example, you could accumulate lots of distance toward a gravel bike upgrade while riding the Cadex Tri in this event.

How We Make Our Picks

We choose each weekend’s Notable Events based on a variety of factors including:

  • Is the event unique/innovative in some way?
  • Are celebrities (pro riders, etc) attending/leading?
  • Are signup counts already high, meaning the event is extra-popular?
  • Does the ride include desirable unlocks or prizes?
  • Does the event appeal to ladies on Zwift? (We like to support this under-represented group!)
  • Is it for a good cause?
  • Is it just plain crazy (extra long races, world record attempts, etc)?
  • Is it a long-running, popular weekly event with a dedicated leader who deserves a shout out?

In the end, we want to call attention to events that are extra-special and therefore extra-appealing to Zwifters. If you think your event qualifies, comment below with a link/details and we may just include it in an upcoming post!
