Beginner runner's glossary: start with the meaning
Pace, intervals, long runs, zone 2 and negative splits appear in training plans and running conversations, but they are not training instructions. Pace describes time per distance; intervals describe efforts alternating with recovery; a long run identifies a longer session within the plan. Understanding the word helps you ask better questions of your professional.
Here, numerical examples explain calculations and concepts. They do not prescribe running frequency, distance, intensity or supplement doses. There is also no pace every beginner must achieve to be considered a runner.
What is running pace?
Pace is the time needed to cover a unit of distance. In Brasil, it is most commonly read in minutes and seconds per kilometer. The calculation is total time divided by distance: in the EXAMPLE of 5 km in 25 minutes, average pace is 5:00 min/km. For 4 km covered in 32 minutes, it is 8:00 min/km.
A lower number represents greater speed, provided the unit is the same. Average pace summarizes the whole route; instantaneous pace attempts to show the pace at that moment and can fluctuate with the signal and measurement. Target pace is the pace planned for a purpose. Knowing the meaning does not define an individual target.
How to convert pace to treadmill speed
Kilometers per hour measure distance over time; minutes per kilometer measure time over distance. To convert, divide 60 by pace in decimal minutes. Note: 7:30 means 7.5 minutes, not 7.30. The table below contains mathematical equivalents, rather than recommended paces.
| Speed | Equivalent pace | How to read it |
|---|---|---|
| 15 km/h | 4:00 min/km | 4 minutes per kilometer |
| 12 km/h | 5:00 min/km | 5 minutes per kilometer |
| 10 km/h | 6:00 min/km | 6 minutes per kilometer |
| 8 km/h | 7:30 min/km | 7 minutes and 30 seconds per kilometer |
| 7.5 km/h | 8:00 min/km | 8 minutes per kilometer |
To test your own calculations, the pace calculator relates time and distance. A calculator result is an equivalence or estimate, rather than an assessment of your fitness.
Splits and negative splits
A split is the time for a section. A negative split means completing the second half faster than the first. EXAMPLE: on a 10 km course, a first half in 30 minutes and a second half in 29 minutes make a negative split. Reverse those times to produce a slower second half.
Having the fastest final kilometer does not establish a negative split: the comparison is between halves of equal distance. The expression describes how time was distributed; it does not establish that this strategy is best for every session or race.
Intervals, long runs and recovery runs: session types
| Term | Meaning | What it does not determine on its own |
|---|---|---|
| Intervals | Efforts alternating with recovery periods | Number, duration, speed or rest interval |
| Long run | A longer session within the context of the plan | A universal minimum distance |
| Recovery run | A name used for a low-effort session | That running is always the best recovery option |
| Continuous run | Continuous running, with a purpose defined in the plan | The same intensity for everyone |
| Warm-up | Preparation for the upcoming activity | A mandatory duration for every session |
| Cooldown | Transition after the main part of the activity | A guarantee of preventing muscle soreness |
The same name can appear in plans with different purposes. Before performing a session, clarify its goal and how effort should be monitored. A workout seen on social media does not become suitable for you because it is labeled beginner.
Volume, intensity and load
Volume describes the amount of work, such as time or distance. Intensity describes effort; it may be expressed through pace, heart rate, perceived exertion or another criterion. Load is a broader term whose definition depends on the method used. Two workouts covering the same distance can represent different demands.
Progression is the planned change in this work over time. The cohort by Frandsen and colleagues (2025) followed 5,205 runners and identified an association between increases in single-session distance, compared with the longest run in the previous 30 days, and overuse injury. The study is observational: it does not establish a percentage that guarantees safety.
In the analysis, the hazard ratio of 2.28 corresponded to the group with an increase greater than 100%, rather than simply a session that doubled. Percentages and associations from this study are not individual traffic lights: staying below a threshold does not eliminate risk, and progression decisions require context.
Zone 2 and perceived exertion
Zones are intensity ranges defined by a system. Zone 2 is not a universal number: its meaning changes with the model and assessment method. An isolated heart-rate percentage can therefore be confusing without stating which system is being used. See the guide to zone 2 and ask how the zones in your plan were defined.
Perceived exertion is how a person rates the demands of an activity. The ability to talk may provide a clue about effort, but it does not precisely identify every physiological zone. Symptoms, terrain, heat and context also need to be part of the conversation with the professional.
Cadence and stride
Cadence is the number of steps per unit of time, usually per minute. Stride length is a different measurement. In the study by Heiderscheit and colleagues (2011), manipulating step rate changed mechanical measurements during running. This does not demonstrate an ideal cadence for every runner or that changing the number on your own prevents injury.
Taper and recovery
Taper is the name for a planned reduction in load before competition. Rest, an easy session and returning after injury are different situations; a glossary word does not replace individual planning. To expand your recovery vocabulary, see the rest guide.
Carbohydrate gels, bonking and nutrition vocabulary
A carbohydrate gel is a form of carbohydrate used in sports strategies. Composition varies: some products also contain caffeine or other ingredients. The need for use and the strategy do not follow from the product's name or a universal running duration.
The review by Podlogar and Wallis (2022) discusses different carbohydrate intake contexts in endurance sports, including amounts above 90 g per hour in specific situations. Therefore, 90 g/h is not a universal physiological ceiling. This glossary does not prescribe doses: choice and quantity require nutritional assessment and the manufacturer's information.
Bonking or hitting the wall is an informal expression for a major performance drop, often associated in sports vocabulary with energy availability. It is not a diagnosis: feeling unwell or losing performance can have different causes. Do not try to explain every symptom as simply a lack of gel.
Gut training is the name for strategies that familiarize the gastrointestinal system with intake during exercise. The review by Jeukendrup (2017) discusses this adaptation. It does not mean persisting with a product despite symptoms or copying another athlete's protocol.
Shoes, GPS and what to ask before buying
Training shoes, plated shoes, GPS watches and heart-rate straps are equipment categories, rather than mandatory stages of progress. The watch records data; the strap measures heart rate; neither replaces assessment or independently defines suitable training. Features, compatibility and warranty should be confirmed with the manufacturer.
| Item or term | Its purpose in the conversation | Question before buying |
|---|---|---|
| Training shoes | Footwear usage category | Do the fit and intended purpose suit the planned use? |
| Carbon plate | A component of some models | Which features does the manufacturer state? |
| GPS | Position, distance and pace estimate | How does the device measure, and what are its limits? |
| Heart-rate strap | Heart-rate measurement | Is it compatible with the equipment and intended use? |
| Gel | A form of carbohydrate delivery | What is its composition, and is it indicated in my eating plan? |
There is no need to turn the first month into a shopping list. Define what you want to measure or solve before choosing equipment. The glossary organizes terms; planning and health decisions remain individual.
How Darwin helps you understand your records
Darwin's approach brings together training planning and records to monitor what was planned and what happened. Pace, time and perceived exertion gain context when viewed across your routine. Recording does not guarantee injury prevention or replace professional guidance.
To learn about the approach, express interest in the Darwin preview as an athlete. The form records your interest; the team contacts you about the preview, and it does not create an account.
