Free indoor cycling just got a real competitor to Zwift’s $19.99-a-month fee. MyWhoosh costs nothing, ships 730+ structured workouts, and drops you into 17+ 3D virtual worlds. It also computes exactly zero training load metrics. Every one of those free rides is invisible to the fitness math that actually predicts injury and burnout.
Here’s the short version. MyWhoosh wins for cost, virtual-world graphics, and racing with real prize money. AthleteOS wins for the season-level load tracking MyWhoosh, Zwift, and TrainerRoad all skip entirely. You don’t have to pick one.

Translation: the top four platforms in indoor cycling are all excellent at getting you pedaling. None of them, MyWhoosh included, tell you whether this week’s pedaling is building fitness or digging a hole.
What’s Missing From MyWhoosh: No Fitness Score, No Fatigue Score, No ACWR
Here’s the gap. CTL (Chronic Training Load) is a 42-day rolling average of your daily training stress. Coaches call it your fitness score. ATL (Acute Training Load) is the same math over 7 days, your fatigue score. TSB (Training Stress Balance) is fitness minus fatigue, your form score. It tells a coach whether you’re fresh enough to race or cooked enough to need a rest day.
MyWhoosh logs your ride files. It does not calculate any of these three numbers. Neither does Zwift. Neither does TrainerRoad, even though reviewers call it the most scientifically grounded structured-training platform around.
There’s a related metric that matters even more for injury risk. ACWR (acute:chronic workload ratio) compares your last week’s training load to your rolling six-week average. Research on the “training-injury prevention paradox” found the safest zone sits between 0.8 and 1.3. Ratios above 1.5 climb into what researchers call the danger zone.
A 2020 systematic review of 27 studies put real numbers behind this. An ACWR above 2.0 for total distance carried a relative risk of injury between 5.87 and 21.28. Session-RPE-based ACWR at or above 1.50 carried odds ratios of 3.03 pre-season and 2.33 in-season.
None of that math runs anywhere in MyWhoosh’s app.
What MyWhoosh Actually Is (And Why It’s Genuinely Good)
Give credit where it’s due. MyWhoosh launched in 2019 out of Masdar City, Abu Dhabi. It’s backed by Emirati businessman Akhtar Saeed Hashmi and is the official indoor platform of UAE Team Emirates, UAE Team ADQ, and Tadej Pogačar. That backing is exactly why it can undercut Zwift’s price to zero.
The content is deep. Riders get 730+ structured workouts and training plans, some built by UAE Team Emirates WorldTour coach Kevin Poulton. The virtual-world roster spans 17+ locations, from AlUla and Arabia to Belgium, Bhutan, and Japan, with rowing added at Lake Bled in January 2026.
Racing carries real stakes too. MyWhoosh hosted a $1 million esports event in April 2023, the largest in cycling esports history at the time. It paid out over $3.75 million across 2024, with monthly prize pools reportedly running $90,000 to $284,000. It’s also held the UCI Cycling Esports World Championship rights since taking them from Zwift in 2023, through 2026.
For a cyclist who just wants a free, well-built indoor session with real racing on the line, MyWhoosh is a strong, honest choice. This isn’t a knock on the platform. It’s a different job.
The Science Behind Load Management: Banister, Coggan, and Gabbett
The CTL/ATL/TSB framework isn’t a MyWhoosh feature gap by accident. It comes from a specific lineage of sports science that indoor cycling apps were never built to run.
The foundation is Eric Banister’s impulse-response model, published in 1975. It treats each day’s training as an impulse that produces a fitness effect and a fatigue effect, each decaying on a different timeline. In validation studies, this model explains over 90% of the variance in measured athlete performance over time. That’s the math underneath every fitness score on the market.
Coggan and Allen built the practical version on top of it. Training Stress Score per ride rolls into the 42-day and 7-day averages that produce CTL, ATL, and TSB. Gabbett and Hulin’s ACWR research added the injury-risk layer.
Here’s why the ramp rate matters day to day. Recommended CTL growth sits around 5-8 points a week for most athletes. Ramp rates above 8 points a week enter what TrainingPeaks research calls the crash-training range, tied to overtraining, illness, and burnout. Only elite athletes tolerate above 10 points a week, and only for about a week before they need recovery.
Picture a phone battery that charges fast but never gets a chance to cool down. It looks fully charged. It’s also the one that swells and fails first.
That’s a rider ignoring ramp rate.
Ride five or six free MyWhoosh sessions a week with no plan behind them and your CTL can climb straight through that danger line with nobody watching.
What MyWhoosh, Zwift, and AthleteOS Cost in 2026
| Platform | Monthly | Annual | Free tier |
|---|---|---|---|
| MyWhoosh | $0 | $0 | Full app, no paywall |
| Zwift | $19.99 | $199.99 | Trial rides only |
| TrainerRoad | Paid subscription | Paid subscription | 30-day trial, no permanent free tier |
| AthleteOS | Free tier + paid AI coach plan | Varies by plan | Performance Management Chart included free |
MyWhoosh’s price advantage is real and structural, not a promotional trick. It’s backed by UAE capital, not subscriber revenue, and that changes the whole cost equation compared with Zwift.
Use MyWhoosh If / Use AthleteOS If
Use MyWhoosh if:
- You want free, high-quality structured indoor workouts with zero subscription cost.
- You want 3D virtual worlds and races with actual prize money on the line.
- You’re chasing a UCI Esports World Championship qualifying spot.
- You just need a trainer app, not a season-long plan.
Use AthleteOS if:
- You want to know your fitness score, fatigue score, and form score every day, not just after a season ends.
- You train across running, swimming, or strength alongside cycling and need one load picture.
- You want an ACWR warning before a spike turns into an overuse injury.
- You want your plan to adapt automatically instead of manually rebuilding it every few weeks.
Most riders land in both camps. That’s fine.
They aren’t competing for the same job.
What AthleteOS Can’t Do
Fair is fair. AthleteOS doesn’t render a 3D peloton climbing AlUla, and it never will. That’s not the product. It has no in-app racing league, no prize purse, no avatar customization, and no 17-world map to explore. If the reason you ride indoors is the game-like experience and the community pack riding, MyWhoosh and Zwift are simply better at that job. AthleteOS is a load-management and coaching layer, not a virtual-world renderer, and pretending otherwise would be dishonest.
MyWhoosh + AthleteOS: Using Both Tools for What Each Does Best
Take a rider named Josh, 34, training for a fall gran fondo on a smart trainer three days a week. He picked MyWhoosh for the free structured plans and rode UAE Team Emirates-style intervals four times a week through June, feeling stronger every session.
By week five his resting heart rate was climbing and his legs felt flat on easy days. MyWhoosh’s app showed nothing wrong. Once he started importing his rides into AthleteOS, his fitness score told a different story: a ramp rate of just over 11 points a week for three straight weeks, deep in the crash-training range. His ACWR had drifted to 1.7.
AthleteOS didn’t tell him to stop riding MyWhoosh. It cut two of his four weekly sessions to easy Zone 2 and flagged a recovery week. Six weeks later his form score sat in a healthy range heading into race day, and he still rode MyWhoosh’s virtual worlds the whole time.
That’s the actual pairing. Keep the free workouts and the world map. Let AthleteOS run the math neither MyWhoosh nor Zwift ever built.
If you’re weighing what belongs in your training stack, the training app comparison for Ironman athletes walks through how load management fits alongside race-specific tools. And every ramp-rate decision starts with a solid aerobic base. How Zone 2 riding builds that base is worth reading before you touch the intensity dial. Structured MyWhoosh rides need fueling behind them too. The 3-day carbohydrate loading protocol covers the fueling side of that same aerobic engine.
Free structured riding is a great deal. It’s a worse deal when nobody’s watching whether it’s building you up or grinding you down.
You can start a free AthleteOS account and see your fitness score, fatigue score, and ACWR the first week you import a ride. Or check the pricing page for the paid AI coaching tier if you want the plan adapting for you automatically.
