Frequently Asked Questions (FAQ)

How does age change my level?

The calculator shows a comparison across all ages and a separate age-adjusted comparison. It applies the selected event and sex's reference age factor to your time before finding the percentile. The highlighted row uses the same reference factor.

Reference factors use the nearest supported whole-year age and event; fractional ages do not create a new fitted population. Where an age is outside the references, the table's note identifies the limit. Some performances also fall outside the supported ranking range.

An age-adjusted percentile compares your performance in this model. It differs from an age-grade percentage against a reference best performance. This calculator does not supply a separate formal age-grade score.

Does bodyweight change my level?

No. For the same sex, age, distance and time, 50 kg and 100 kg give the same level in this version. It is not a bodyweight-class ranking.

There is no height adjustment in these standards. The selected comparison data do not provide a validated height-based ranking; adding a height correction would imply evidence this version does not have.

Bodyweight affects estimated power, calories and VO2 max through the bicycle assumptions. These supplementary estimates are separate from the newer time-based rank.

Which cycling performances can I compare?

Road speed depends on gradient, wind, bicycle, riding position and drafting. Stationary-bike distance is not a validated substitute for road distance. Estimated watts and VO2 use a simplified bicycle model; they are not measured power or oxygen uptake.

The newer speed standards do not identify a verified road-bike, mountain-bike, hybrid or cruiser population. We do not offer separate bicycle or hill adjustments. The supplementary power model assumes level conditions; that assumption does not make the submitted rides a verified flat-course cohort.

The historical bicycle equation uses an 8.8kg bicycle, drag area 0.3m², rolling-resistance coefficient 0.004, 0% gradient and 0m/s wind. Its atmosphere inputs are 101,300Pa and 20°C. These fixed assumptions do not describe every rider's equipment or conditions.

Submissions do not establish identical start, route or timing protocols. Use consistent distance and timing when comparing your own performances; a supported percentile does not prove comparable conditions.

Published 200m track references use flying starts. Other events can have standing, flying or time-trial references; each record's details show its actual protocol. The standards' submission starts remain unknown.

Moving and elapsed ride times are not verified separately in the submitted population. Stops, traffic, load and terrain can change the comparison. Use a consistent timing method for your own progress. The current model supports up to 200km; a 280km ride is outside its range and cannot receive an overall-endurance rating here.

Are equivalent times race predictions?

They show times at the same percentile of this version's model over other distances. Different events can represent different groups of athletes. These comparisons do not guarantee every time without event-specific preparation.

What does the finish-time chart show?

The curve estimates relative frequency from the selected model, rather than counting observed results in time bins. Faster times are to the right. Percentages describe how many performances are slower within this comparison.

Your marker keeps the submitted time and the result's age-adjusted percentile. The curve uses the same age reference as your standards row. Charts normally display the 1st to 99th percentiles and extend to include your result when it falls outside that window. That display window does not limit your rating.

Interpolated distances use neighbouring event models. Running ultra estimates extend the marathon relationship; longer swimming estimates extend the shorter-distance fit. These are not independent observed distributions at every distance.

How is VO2 max calculated?

Levels describe this event's model comparison, not your training history or ability in every sport. Elite is a population percentile, not a professional qualification. Use a recent best test or race effort for a meaningful benchmark; standards are not a pace target for every workout.

What are qualifying results?

Each community result is a distance and time entered in the Cycling Level calculator. Qualifying results are the results retained after checks for implausible data, duplicates, and unusual or automated submission patterns, followed by checks for each distance.

We select the best result for each user, sex and event, then use the qualifying results to develop and check our standards. The timing pages show the available qualifying, male and female result counts for each event. The overall standards page shows how many results passed the initial quality checks, before event selection and further filtering.

How are users counted?

User counts estimate how many people submitted results, using distinct submission IP addresses. Shared addresses and address changes mean these are approximate counts. One user can submit several results and contribute to more than one event.

We will continue to update our standards as more community data becomes available. See our standards timeline.

Where do the standards and records come from?

Newer standards use self-reported Cycling Level submissions. They describe that comparison, not all people or a verified race-entry population. One person can submit multiple performances; approximate identity checks do not establish a count of verified athletes.

The selected version fixes the data and model used in your result. New data can lead to a later version. Sources identify inputs and methods without implying endorsement.

New releases follow reviewed data quality and model checks, with no fixed update interval. We do not have a verified geographic breakdown of submissions. The standards pages give the available counts and source limitations.

Available record figures open the corresponding event, athlete, age/category, performance date and source. Missing records stay unavailable. Some sources list best performances rather than a ratified record register; check categories and source selection before treating every entry as a ratified world record.

A fitted percentile can extend beyond an observed record. It estimates the comparison population and is not evidence that a record has been achieved or could be achieved under that record's rules. Age adjustments, equipment and event categories can also differ; use the record's details when comparing them.

Which records are used?

Published individual performances come from UCI, USA Cycling, VTTA and WUCA. WR means world record and NR means national record. Age rows select the fastest available record in each five-year band; start types, surfaces and published categories vary.
