Indoor, Virtual and Esports Triathlon

Direct-drive trainers replace the rear wheel with their own cassette, removing tyre slip and wear.

A smart bike is a standalone indoor bike, so the rider's own bike stays free and set-up time disappears.

Source: Indoor-cycling and smart-trainer reference · recall

To hold the same watts at a lower cadence the trainer adds torque, which can spiral until the rider stalls.

Source: Indoor-cycling and smart-trainer reference · applied

Tyre pressure, temperature and clamp tension alter rolling resistance, so a spin-down resets the trainer's estimate.

Source: Indoor-cycling and smart-trainer reference · recall

Premium trainers are usually specified at about 1-2%, similar to many crank or pedal power meters.

Source: Indoor-cycling and smart-trainer reference · recall

With virtual shifting the bike runs a single sprocket and the trainer changes resistance to imitate gear changes.

Source: Indoor-cycling and smart-trainer reference · recall

Heat and friction on the roller wear road tyres quickly; harder trainer tyres last longer and grip better.

Source: Indoor-cycling and smart-trainer reference · recall

A rocker plate lets the bike move laterally, which many riders find more comfortable and closer to outdoor riding.

Source: Indoor-cycling and smart-trainer reference · recall

A heavier flywheel stores momentum, so the pedal stroke feels less choppy and closer to riding outdoors.

Source: Indoor-cycling and smart-trainer reference · recall

Smart trainers are controlled over ANT+ FE-C or Bluetooth FTMS, which lets apps read power and set resistance.

Zwift models drafting, so sitting in a group means a rider needs fewer watts for the same virtual speed.

Source: Virtual training platform reference (Zwift and similar) · recall

Trainer difficulty scales how much of the gradient the trainer applies; speed still comes from power and weight.

Source: Virtual training platform reference (Zwift and similar) · recall

Virtual speed is calculated from power and weight, so watts per kilogram decides how fast a rider climbs.

Source: Virtual training platform reference (Zwift and similar) · recall

Platforms guide the rider through planned intervals, often controlling the trainer in ERG mode.

Source: Virtual training platform reference (Zwift and similar) · recall

Power rises step by step until the rider fails, and FTP is estimated from the best minute's power.

Source: Virtual training platform reference (Zwift and similar) · recall

The estimate takes a set share of the best minute's power, which overestimates FTP in riders with strong anaerobic power.

Source: Virtual training platform reference (Zwift and similar) · recall

Items like the feather (lighter) or aero boost give a short in-game advantage and add a tactical element.

Source: Virtual training platform reference (Zwift and similar) · recall

Group rides make long indoor sessions more engaging and give a pace to follow, while avoiding winter roads.

Source: Virtual training platform reference (Zwift and similar) · recall

Structured sessions scale every interval from FTP, so an outdated figure makes the targets too easy or too hard.

Source: Virtual training platform reference (Zwift and similar) · recall

Drag, rolling resistance and drafting are modelled differently, so identical watts do not give identical speeds.

Source: Virtual training platform reference (Zwift and similar) · recall

A mat catches sweat, damps vibration and noise, and stops the trainer sliding on smooth floors.

Source: Indoor-training physiology reference · recall

This cardiac drift comes from heat build-up and dehydration, which is why cooling and drinking matter indoors.

Source: Indoor-training physiology reference · applied

Sweat is salty and falls in the same places for hours, corroding headsets, bolts and components.

Source: Indoor-training physiology reference · recall

Without airflow or cold, even a light session makes a rider hot, so minimal clothing is normal.

Source: Indoor-training physiology reference · recall

Heat builds up indoors, raising sweat losses, so fluid needs can exceed those of an outdoor ride.

Source: Indoor-training physiology reference · recall

On a static bike the rider shifts and stands less, keeping pressure and friction on the same spots.

Source: Indoor-training physiology reference · recall

Structure, company and goals make long indoor sessions easier to sustain than steady unstructured riding.

Source: Indoor-training physiology reference · recall

Hours in the race-day position, especially on aero bars, build the comfort and strength to hold it.

Source: Indoor-training physiology reference · recall

Moving straight from the trainer to a treadmill practises running on cycling-tired legs.

Source: Indoor-training physiology reference · recall

Training in a warm room raises core temperature and can contribute to heat adaptation; it needs careful monitoring.

Source: Indoor-training physiology reference · recall

Jones and Doust (1996) found a 1% gradient best reflects the cost of outdoor running at typical training speeds.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Moving through still air adds drag outdoors; a small incline compensates for it on a treadmill.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Indoors, watches estimate pace from arm or foot motion, which drifts unless calibrated; belts can also be off.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Belt stretch, motor wear and load change the true speed, so treadmills can be off unless checked.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

The curved belt moves only as the runner pushes it, so speeding up means running harder, not pressing a button.

Research finds treadmill and overground running broadly alike, with small differences in stride and feel.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Without forward movement there is no cooling breeze, so heat builds up as on the trainer.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Treadmills are consistent, but outdoor courses bring hills, turns and uneven surfaces the legs must adapt to.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

A treadmill fixes pace and gradient precisely, useful for controlled intervals or safe running in bad weather.

Source: Treadmill-running research (Jones and Doust, 1996) and running reference · recall

Setting the incline lets an athlete rehearse long climbs even without hills nearby; downhill needs special models.

Supplied, checked trainers in one place make power data comparable and harder to manipulate.

Source: UCI cycling esports rules and virtual-racing fair-play reference · applied

Sanctioned events check rider data; everyday races mostly trust what riders enter.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

A lighter entered weight makes the avatar climb faster for the same power.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

Platforms estimate frontal area from height and weight, so a false height changes virtual drag.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

A second power source, such as pedals or cranks, lets organisers check that trainer data are genuine.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

Riders weigh themselves on camera, often shortly before or after the race.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

Sandbaggers hold their ratings down to race and win against slower categories.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

Categories ran from A (the strongest, around 4 W/kg or more) down to D.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

A single W/kg figure missed sprinting and tactics; result-based ratings group riders by how they actually race.

Source: UCI cycling esports rules and virtual-racing fair-play reference · applied

Tampering with calibration or settings can make a trainer over-read, which is why dual recording exists.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

The rider produces real power, so performance-enhancing drugs would work just as they do on the road.

Unverified or suspect data can lead to disqualification or sanctions under the event's rules.

Source: UCI cycling esports rules and virtual-racing fair-play reference · recall

On climbs virtual physics weighs power against weight, so W/kg decides.

Source: Virtual training platform reference (Zwift and similar) · recall

On the flat, drag dominates and gravity matters little, so absolute watts carry more weight than W/kg.

Source: Virtual training platform reference (Zwift and similar) · recall

Falling off the front group early means losing the draft, so the start is often the hardest part.

Source: Virtual training platform reference (Zwift and similar) · recall

As on the road, riding in the draft lets a rider hold speed for fewer watts.

Source: Virtual training platform reference (Zwift and similar) · recall

Reducing drag pays off where speed is high, such as a flat sprint.

Source: Virtual training platform reference (Zwift and similar) · applied

Lower weight helps most where gravity dominates, on uphill sections.

Source: Virtual training platform reference (Zwift and similar) · applied

Avatars corner automatically, so the gaps real descending skill creates largely disappear.

Source: Virtual training platform reference (Zwift and similar) · recall

A sprint finish rewards timing and peak power over a few seconds.

Source: Virtual training platform reference (Zwift and similar) · recall

Pack racing rewards surges and sitting in the draft; a non-drafting leg needs steady solo pacing.

Source: Virtual training platform reference (Zwift and similar) · applied

Virtual racing is full of accelerations, while time-trialling rewards even pacing.

A pump moves water past a stationary swimmer, so they can swim continuously in a small space.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

The swimmer is held in place by a cord, so they can train in a tiny pool or load the stroke for strength.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

With no forward movement only effort or force can be tracked, not pace per 100 m.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

The athlete lies on a sliding bench and pulls cords or paddles to train swim-specific strength and endurance.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

The current sets the pace and the view never changes, so navigation and pack skills must be practised elsewhere.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

Each push-off adds speed and a brief rest, which open water never offers.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

More walls mean more push-offs, each faster than free swimming.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

Lifting the eyes briefly to a marker on the end wall rehearses the open-water sighting movement.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

Short sessions let an athlete get used to the buoyancy and shoulder restriction; warm pools make long ones uncomfortable.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

A buoy lifts the legs like a wetsuit, but neoprene also resists shoulder movement, which a buoy cannot mimic.

Source: Swim training reference (pools, flumes and dryland equipment) · recall

Many indoor events fix the time for each leg and rank athletes by total distance swum, ridden and run.

Source: Virtual and indoor event reference (IRONMAN VR, indoor triathlon formats) · recall

With mass events cancelled during the pandemic, organisers moved racing online.

Source: Virtual and indoor event reference (IRONMAN VR, indoor triathlon formats) · recall

Athletes completed distances where they lived within a set window and uploaded their device data to be ranked.

Source: Virtual and indoor event reference (IRONMAN VR, indoor triathlon formats) · recall

Without officials, results rely largely on trust in uploaded GPS and sensor data.

A short indoor event gives a fitness marker and transition practice before the outdoor season.

Source: Virtual and indoor event reference (IRONMAN VR, indoor triathlon formats) · recall

Athletes move between the pool, a gym bike and a treadmill, so transitions are short walks or runs.

A footpod or smart treadmill sends speed and cadence so the runner's avatar moves in the virtual world.

Source: Virtual and indoor event reference (IRONMAN VR, indoor triathlon formats) · recall

Static bikes and treadmills are calibrated differently, so a kilometre on one machine may not equal another.
