A regular participant on the RWOL Beginner’s Forum named Jenny (screen name “thelearnedfoot”)
posted a very useful list of definitions of running and forum terminology and jargon. Her intent was for it to serve
as an aide for beginning runners to better and more quickly understand various forum discussions. Several other forum participants
posted suggested additions to her original list. The following compilation of Jenny’s original list (90% of the total

A Guide To Terminology and Jargon for New Runners
Your friendly beginning runner's guide to .... runner's jargon. J
notice we don't have a FAQ here on the Beginner’s Forum -- that's because we want you to ask your questions, join in,
become part of the community! That said, I am sure new runners get overwhelmed by phrases we throw around all the time here
with impunity; you probably think we're all speaking some strange language. To follow along here, it's really helpful just
to know some general stuff and what terms mean. So in the interest of helping out new runners, here's a guide to some running
terminology. If there are terms I've missed, please someone add them. Or feel free to clarify or add info. And any newbies
out there who want another term you see here and wonder about explained, please ask. The veterans here are happy to help you
some different types of runs you will see referred to on the board. All of these types of runs are done to accomplish different
goals and objectives.
The easy run or a recovery run is simply a run at an easy pace done for recovery
purposes or just simply enjoyment. Most of a beginner’s runs should be easy runs. These runs improve a runner’s
aerobic conditioning. The intensity of these runs should permit conversing using complete sentences (60-75% of your maximum
Jogs usually refer to slow running done to recover between intervals. Runners and (especially)
non-runners will sometimes use the term "jog" for a slow run for exercise. Runners tend to prefer to refer to what they do
as running; but usually know that if a non-runner refers to you as a jogger, they probably don't mean any harm.
Runs are typically 25-30% of your weekly mileage or so and are usually done once a week. These are usually done at a comfortable,
fairly easy pace. We often refer to them here as LSD -- long, slow distance or long steady distance. An appropriate long run
distance is determined by your goals. A long run might be anywhere from 5 miles to 25 or more (for an ultramarathoner).
pace runs" refer to running your predicted or expected race pace. So if a workout were to call for doing miles at "marathon
pace," that means running at your predicted marathon pace per mile. That could be anything from 5:00/mile for someone fast
to 12:00 minutes a mile for someone slower. A 5K race plan may call for doing intervals (explained below) at your 1 mile race
pace. A good way to figure out your expected paces is to use an online calculator. The McMillian Calculator is excellent.
A tempo run is a run at around your 10-15K
race pace (or about 80-85% of your maximum heart rate or so). Traditionally tempo runs were 20 minutes or so in length, but
they vary. It's often described as being "comfortably hard" -- it's a challenging, but manageable pace. You want to finish
a tempo feeling challenged, but not exhausted. Most tempo runs consist of ten to fifteen minutes of easy running, then the
tempo part, then ten to fifteen minutes to cool down. Tempo runs build speed and teach your body to run at a certain pace.
Related to tempo runs are cruise intervals. Like tempo runs, these runs are designed to help you learn to deal
with the accumulation of blood lactate; they are sometimes called lactate threshold (see Physiological Terms) runs. Cruise
intervals are usually 3 to 15 minutes in length, with 1 minute or so of recovery for each five minutes of run time.
fartlek is a fun word that you can say and make non-runners snicker. It simply is an informal way of doing speed work.
It's a Swedish word meaning "speed play." In a fartlek, you would run hard to say the next telephone pole, then slow down,
then run hard again to the next object. It's just basically bursts of speed in the middle of a workout. It can be easy or
hard. There's no set distance or speed, it's very loose and informal. Fartleks are good for a beginning runner who wants to
dabble in speedwork.
Intervals (sometimes called "repeats") usually refer to track work, though you can do them
elsewhere. Usually intervals consist of a set distance (say 400 meters, 800 meters, a mile) that you run at a set, usually
fast pace. Between the intervals, you would recover by either jogging slowly or walking. People often do them on the track
because the track is obviously measured. An example of an interval workout might be 4x800. This means you are going to run
four sets of 800 meters (or about a half mile) at a certain pace. Between those faster runs, you will walk or jog to recover.
Often an interval workout will give you the pace you're supposed to run and the time you should take to rest. Usually rest
time is roughly equivalent to how much time it takes you to run the distance. So in our 4x800 example, if you were doing the
800s in 4:00 minutes (8:00 mpm pace), you would take about 4:00 rest. Intervals build speed and improve aerobic capacity (See
Just a brief word about the track .... If you visit the track to do a workout, know that most
tracks are 400 meters in length. (There are some quarter mile tracks, but most are 400 meters.) A mile is roughly equivalent
to 4 laps around the track. A mile is actually a little longer than 1600 meters. If you want to do a true timed mile, find
the common finish line. (It's usually located at or near the end of the straightaway in front of the home stands. Usually
has numbers painted there.) Go back 9 meters and there should be a line. That’s where the mile would end.
Repetitions are a form of repeats that are faster and shorter than intervals
with full recovery between them (usually 4-6 times as long as the repetition). These are used for improvement of anaerobic
capacity, running form and running economy.
A ladder is an interval workout of increasing interval lengths,
such as 200-400-600-800 meters.
A cutdown is the opposite of a ladder or an interval workout of decreasing interval
lengths, such as 800-600-400-200 meters.
A pyramid is a combination of a ladder and a cutdown, such as 200-400-600-800-600-400-200
will also hear about hill repeats -- these typically are runs up a hill at a fast pace to build strength. I personally
hate hill repeats, so I prefer to run hilly courses instead.
Strides are short, controlled bursts of running
of 50 to 150 meters designed to improve efficiency, work on form, etc. Often done at the end of a run.
is a period of slower running prior to faster running. Cool down, sometimes
called warm down, is slower running at the end of faster running.
Aerobic means using oxygen to generate energy.
Anaerobic means generating energy without oxygen.
Lactic acid in working muscles is a byproduct of anaerobic energy generation.
Aerobic capacity or VO2Max is the maximal amount of oxygen that a person can extract from the atmosphere, send to the body's tissues, and consume
to produce energy. You can use your current VO2Max to estimate your times for intervals, for example. (Find your vo2max by entering a recent race or run time.)
Lactate threshold (LT), is the level of intensity at which anaerobic energy generation begins to rise and the resulting generation
of lactic acid in working muscles causes blood lactate to rise and muscle efficiency to fall off significantly with fatigue.
vVO2max is the velocity or pace at which a person
vLT is the velocity or pace at which LT is reached.
Anaerobic capacity is a runner’s maximum ability
to run very fast … beyond VO2max where all additional energy to run faster than vVO2max is generated anaerobically.
Runners can sustain such fast paces for only a few minutes.
Running economy is a measure of the amount of oxygen used to run a given pace. More
economical runners use less oxygen to run a specific pace than do less economical runners. Running economy is improved through
Resting heart rate is your heart rate when you first
wake up and before rising.
Maximal heart rate (HRmax or MHR) means the maximum heart rate that can be reached while running. Training intensities are often determined
by percent of HRmax.
Heart rate reserve (HRR or HRres) is the difference between HRmax and RHR (HRmax - RHR = HRR). Some runners base training
on percent of HRR instead of HRmax.
Anterior is front.
Posterior is back.
Medial is inside or facing the middle
of the body.
Lateral is outside or facing the side of the body.
Some very commonly used abbreviations for running terms used universally (here and just about everywhere):
and PB refer to the same basic thing, running your Personal Best or setting a Personal Record. For example "I ran a PR
in that race" means I ran my fastest time ever at that distance. You can have multiple PRs, say for a course or a distance
or even for the year. You decide.
LSD is long slow distance or long steady distance.
FF means gradually picking up speed during a training
run, such as a LSD, until nearing race pace at end.
MP is marathon pace.
is goal marathon pace.
BQ is to Boston Qualify; the Boston Marathon requires runners to meet a certain time standard
based on gender and age. For example, to BQ a 18 year old male must run a marathon in 3 hrs 10 minutes and 59 seconds or faster.
refers to the illotibial band syndrome, a common overuse running knee injury.
MHR is maximum heart rate.

FE is forum encounter, which is an “offline”
meeting of two or more forum participants, often at a race.
NRR means “not running related”.
DW,DH,DD,DS means dear wife,husband,daughter,son,
etc...(can also mean damn wife, husband, etc. J)
Splints is pain anywhere between your knee and your ankle. They are more of a symptom of an underlying condition than
a condition in itself. The problem could be a stress fracture, medial tibial stress syndrome, compartment syndrome, inflammation
of connective tissue (periosteum) known as periostitis ... Multiple causes, multiple solutions, even possibly multiple
possible injuries might be causing shin splints. Very common, especially in new runners. Shin splints are typically manifested as anterior (front of lower leg) or medial (inside,
facing the other leg) pain. A pain in the back of your lower leg is not shin splints, it's probably a calf strain.
Knee is a condition called Chondromalacia patella. That's why we call it runners knee. PFS (Patello-Femoral Syndrome), which is the kneecap (patella) rubbing on the front of the thigh bone (femur),
is another form of Runner’s Knee. It’s most often caused by overuse, doing too much too soon, ostheoarthritis,
insufficient muscle development and/or improper alignment, including wrong or worn-out shoes or running on slanted pavement.
Trots refer to gastrointestinal problems on the run.
Stitch is a side cramp, usually on the right side.
means to run out of energy, to "hit the wall" ... It's not fun.
Plantar Fasciitis is an often chronic problem
of the foot that can be very painful.
Stress fracture is a hairline crack in a bone.
Illiotibial band syndrome (ITBS) is inflammation
of the illiotibial band, which runs on the outside of the leg from the hip to just below the knee. The injury most often occurs
where the band crosses over the outside of the knee, but can also occur at the hip.
Piriformis Syndrome means a pain in the bottocks.
Tendinitis is inflammation of a tendon. Tendons connect muscles to bones. Tendinitis due to running can occur in a runner’s
groin area, buttocks, legs, feet and lower joints. ITBS is a common form of tendonitis.
to 5k or C25K is a beginners running plan. Couch 2 5K site.
Bandit is someone who runs in a race who hasn't registered.
This is frowned upon.
GU is a type of energy gel. Gels are a semi-liquid sugary snack used for a quick energy
Ultramarathon is simply any race that's longer than the marathon. All marathons are 26.2 miles.
fabric refers to technical fabrics that draw sweat away from the skin. Also might be referred to as say a "tech shirt."
shorts are higher cut running shorts often used in racing.
Cross training or XT is another aerobic exercise such as swimming, cycling, cross country skiing used to complement
running or when you are injured and can't run.
Doubles refers to doing two runs in the same day. Singles would
be doing just one run. So if someone says "I did 50 miles this week, all singles" they are saying "I ran 50 miles this week,
all as once-a-day runs."
Kick is usually used as in "finishing kick" -- simply means running harder at the finish
line, the last final sprint.
Rabbit is someone who goes out with the intention of setting a fast pace in a race,
but then often drops out.
Foot strike refers to how your foot initially impacts the ground as you run. There
are heel strikers, midfoot strikers, and forefoot strikers.
Out and back means a course you run out a certain
distance, then turn around and run back. A loop is simply that -- you start in
one spot and run in a big circle. Point to point means a course that begins and
ends at widely separated locations.
Pronation is the inward roll of your
foot during a running stride.
Overpronation is where your foot rolls over to the
inside too far during the running stride, which can lead to an injury, such as ITBS. Usually you can tell your overpronating
if you have excessive wear on the inside part of the forefoot of the shoe.
Supernation is where your foot rolls to the outside
during the running stride, which can also lead to an injury.
Cushioned refers to a shoe designed for a neutral foot that
does not overpronate or that may supinate. Supinaters land on the outside of their feet.
Stability refers to
a shoe designed for an average arched foot; it offers some degree of control for overpronation.
are shoes that offer the most overpronation control.
Splits are your times in a race or workout at several
measured intervals. For example, a 36:00 minute 4-mile run might have mile splits of 9:00, 8:50, 9:10, 9:00. Splits can also
refer to cumulative times, e.g. if you are running 8:00 min/miles, your split times will be 8:00 at Mile 1, 16:00 at Mile
2 and so on.
Negative splits refers to running the second half of the race faster than the first. The opposite
of negative splits is positive splits where you run the first half faster than
the second. Even splits would be running essentially the same time (within 2-3%)
for both halves of the race.
Taper is where a runner cuts back mileage before a big race like a marathon or
even a shorter race. Tapering runners often get cranky and/or sort of paranoid since they aren't running as much leading to
jokes about "TAPER MADDNESS."
Master is an athlete 40 years of age or older.
Elite refers to those
really super fast folks who usually don't have to pay for shoes because they get them sponsored.
10% Rule is
a general guideline that says don't increase your weekly mileage by more than about 10% each week.
to a little thing you tie on your shoe that measures finishing time when you cross a mat in a race.
are runs at an easy pace done in order to reach a weekly or monthly mileage total rather than for any specific benefit. A
lot of people say no miles are junk, though! J
Kill is a runner who has
been passed by a faster runner during a race.
Ghost Runner is someone (imagined or not, as the case may be)
who is on your heels and about to pass you, used for motivation to keep up the pace.
Garmin refers to the Garmin Forerunner line of handheld Global Positioning System (GPS) devices.
