RUNNING

GLOSSARY

RECOVERY MODALITIES

Foam Rolling/Self-Myofascial Release – Using tools to massage tight spots. Can help 50+ runners maintain mobility.  WARNING: don’t use it to justify running through pain.

Compression Therapy – Using pneumatic devices or garments to enhance circulation. Potentially useful for older runners with slower recovery, but not a substitute for adequate rest.

Cold Therapy/Ice Baths – Deliberate cold exposure for recovery. Growing evidence for benefits, but Henderson would say: consistency matters more than any single recovery method.

Heat Therapy/Sauna – Using heat for recovery and adaptation. May help older runners with circulation and heat tolerance, but don’t complicate what should be simple.

Massage Therapy – Professional soft tissue work. Valuable for 50+ runners.  Good massage is a luxury that can become a necessity as you age.

Red Light Therapy – Low-level light treatment claimed to enhance recovery. Mind you… sleep and easy running are still your best recovery tools.

Mobility vs. Flexibility – Mobility is active movement through range of motion; flexibility is passive. 50+ runners need more mobility work than static stretching.

Breathwork – Focused breathing practices for stress management and recovery. It’s simple, free, and you can do it anywhere.

Modern monitoring terms

HRV (Heart Rate Variability) – Measure of nervous system recovery. Useful data for 50+ runners.

RPE (Rate of Perceived Exertion) – 1-10 scale of how hard something feels. More reliable than pace or heart rate for older runners whose responses change with age.

Recovery Metrics – Data from devices about sleep quality, HRV, resting heart rate. Interesting information, but your energy level and mood are still the best indicators.

Sleep Stages – Light, deep, and REM sleep phases. Modern devices can track these.  Bottom line: do you feel rested?

Core philosophy terms

Easy Running – The foundation of everything. If you can’t hold a conversation or hum a tune, you’re going too hard. This isn’t jogging; it’s purposeful movement at a sustainable effort. For most 50+ runners, this should be 90% of your running.

The Long Game – Running with your future self in mind. Every decision you make today should serve the runner you want to be at 60, 70, and beyond. Not about this season’s PRs.

Sustainable Pace – Your body’s honest assessment of what it can handle day after day, week after week. Ignore your GPS; listen to your breathing, your legs, your energy levels.

Running Honest – Accepting what your body can actually do today, not what it could do 20 years ago or what you think it should do. The opposite of ego-driven running.

Show Up, Don’t Show Off – A 50+ male philosophy that consistency trumps intensity. Better to run 20 minutes easy every day than to hammer one workout and need three days to recover.

PACE and effort terms

Conversational Pace – The gold standard. You should be able to chat with a running partner or answer a phone call without gasping. If you can’t, slow down.

Recovery Run – A misnomer for most 50+ runners. A gentle effort that keeps you moving without adding stress.  Some call it a “maintenance run.”

Tempo Run – For 50+ runners, this means “comfortably hard” effort you could sustain for 45-60 minutes. Not the anaerobic suffer-fest younger runners do.

Fartlek – Swedish for “speed play.” Gentle pick-ups during easy runs when you feel good, not prescribed intervals that beat you up.

Negative Split – Running the second half of a run or race faster than the first. Start easier than you think you should.

TRAINING CONCEPTS

Base Building – The aerobic foundation that supports everything else. For 50+ runners, this never ends—you’re always building or maintaining base, never “peaking.”

Active Recovery – Movement that promotes healing: easy walking, gentle swimming, yoga. Not sitting on the couch calling it “rest.”

Cross-Training – Activities that support your running without the impact: swimming, cycling, rowing. Essential for older runners to maintain fitness while reducing injury risk.

Periodization – Formal term for varying your training. Run more when life allows.  Run less when it doesn’t. Listen to your body, not a rigid schedule.

Taper – Reducing training before a race. For 50+ runners: start tapering earlier and longer than you think you need.

Health and recovery terms

Recovery Window – The time your body needs to fully repair from a workout. At 50+, this can be 48-72 hours instead of 24. Plan accordingly.

Heart Rate Zones – For 50+ runners: if you can’t breathe through your nose, you’re probably too high.

Lactate Threshold – The effort level where your body switches from primarily burning fat to carbohydrates. Not worth obsessing over, but good to understand it rises with age.

Resting Heart Rate – Your pulse when completely at rest. A good daily indicator of recovery status. Rising RHR often signals you need more rest.

Sleep Debt – Accumulated fatigue from insufficient sleep. For 50+ runners, poor sleep is a bigger threat to performance than any training error.

Circadian Rhythm – Your body’s internal clock. Becomes more important with age; why consistent sleep/wake times and morning light exposure matter for 50+ runners.

REM Sleep – Rapid Eye Movement sleep crucial for cognitive function and emotional processing. Often disrupted in older adults; affects decision-making during runs.

INJURY prevention terms

Overuse Injury – Damage from repetitive stress without adequate recovery. The 50+ runner’s biggest enemy. Prevention beats treatment every time.

RICE Protocol – Rest, Ice, Compression, Elevation. “Listen” to what your body is telling you.

Biomechanics – How your body moves while running. Changes with age; shoes and form that worked at 30 may not work at 50.

Proprioception – Your body’s sense of position and movement. Declines with age; why balance and stability work become crucial.

IT Band – Iliotibial band, the tendon running from hip to knee. Common trouble spot for older runners. Foam rolling helps, but prevention through proper training is better.

Plantar Fasciitis – Inflammation of the tissue connecting heel to toes. Often the first injury that gets 50+ runners’ attention about recovery and proper footwear.

EQuipment terms

Rotation – Using multiple pairs of shoes in rotation. Essential for 50+ runners to prevent overuse injuries and extend shoe life.

Motion Control – Shoes designed to limit overpronation. Many older runners need more support as their biomechanics change.

Drop – The height difference between heel and toe in your shoe. Lower drop often works better for older runners with changing gait patterns.

Compression Gear – Clothing that applies pressure to muscles. Can aid recovery for 50+ runners, but not a magic bullet.

nutrition and hydration

Bonking/Hitting the Wall – Running out of glycogen (stored carbohydrates). More common in longer races; can be delayed with proper fueling strategy.

Electrolytes – Minerals lost through sweat. Older runners often need more attention to replacement, especially in hot weather.

Hydration Strategy – Pre-race, during-race, and post-race fluid intake plan. More critical for older runners who don’t regulate temperature as efficiently.

Post-Run Window – The first 30-60 minutes after hard effort when your body most efficiently replenishes glycogen. Matters more for older runners with slower recovery.

MINDSET TERMS

Process Goals – Focusing on what you can control (effort, consistency, attitude) rather than outcomes (times, placements). The preferred approach for 50+ runners.

Intrinsic Motivation – Running for internal satisfaction rather than external validation. Essential for long-term adherence as you age.

Relative Effort – How hard something feels to you personally, regardless of pace or external measures. Your most important training metric.

Running Age vs. Calendar Age – How long you’ve been running consistently vs. your chronological age. A 50-year-old with 5 years of running experience is a different athlete than one with 25 years.

weather and seasonal terms

Heat Index – Combination of temperature and humidity that indicates actual physiological stress. Older runners are more susceptible to heat-related problems.

Dew Point – Humidity measure that affects how well you can cool through sweating. More relevant than relative humidity for running comfort.

Base Layer – Next-to-skin clothing for temperature regulation. Becomes more important as you age and lose some ability to regulate body temperature.

Seasonal Affective Running – Adjusting your running expectations based on weather, daylight, and seasonal energy changes.

Social and community terms

Running Partner – Someone who runs at your pace and shares your philosophy. Worth their weight in gold for consistency and motivation.

Pace Group – Organized group aiming for specific race time. Can be helpful for 50+ runners who need external pacing discipline.

Running Club – Local group for training and socializing. Essential for older runners who might otherwise lose motivation or become isolated.

Mentor Runner – Older, experienced runner who models good practices. Every 50+ runner should be one for someone younger, and seek one who’s older.

Race and event terms

Age Group – Your competition category based on age.  Remember: you’re only racing the guys who showed up, not some imaginary standard.

Age Grading – A system that adjusts your time for age and gender. Helps 50+ runners compete fairly against their younger selves.

Chip Time – Your actual race time from start to finish line. More accurate than gun time for crowded races.

Negative Split Strategy – Starting conservatively and speeding up if you feel good.

DNS/DNF – Did Not Start/Did Not Finish. Sometimes the wisest choices you can make. Your ego will recover faster than an injury.

Masters Division – Age 40+ in most races. Where 50+ runners can compete meaningfully against peers rather than 22-year-olds.

SPECIAL TERMS

Gentle Running – A preferred term for what others call “easy running……………..”

LSD – Long Slow Distance, coined by Arthur Lydiard as the signature training method. Not about time or pace, but about extending your aerobic capacity gently.

Fun Run Mindset – Approaching even serious training with playfulness and joy. The antidote to the grim determination that burns out older runners.

Lifetime PR – Personal record that matters most: years of consistent, enjoyable running. More valuable than any single race time.

Running Real – Term for honest, sustainable running that acknowledges your actual abilities and circumstances rather than chasing fantasies.

Medical terms

Sarcopenia – Age-related muscle mass loss, starting around age 30 and accelerating after 50. Running alone won’t prevent it; strength training becomes non-negotiable, not optional.

Cardiac Drift – Heart rate increase during exercise without increased effort. More pronounced in older runners; affects pacing strategy.

Metabolic Flexibility – Your body’s ability to switch between burning carbs and fat for fuel. Declines with age; easy aerobic running helps maintain it better than constant high-intensity work.

Insulin Resistance – When cells don’t respond well to insulin, often leading to type 2 diabetes. Regular easy running is one of the best preventions, but diet matters more than pace.

HRV (Heart Rate Variability) – Measure of how your nervous system is handling stress and recovery. Useful data for 50+ runners, but don’t let it override how you actually feel.

Sleep Apnea – Breathing interruptions during sleep that destroy recovery quality. More common after 50; affects running performance more than most realize.

Arthritis – Joint inflammation that many 50+ runners face. Running can help or hurt depending on approach and severity.

Osteopenia/Osteoporosis – Bone density loss that accelerates with age. Weight-bearing exercise like running helps, but impact work and strength training become crucial.

Testosterone/Hormone Decline – Natural reduction in key hormones affecting recovery, muscle mass, and motivation. Understanding this helps set realistic expectations for training and recovery.

Chronic Inflammation – Body’s prolonged stress response that increases with age. Easy running can reduce it; too much hard running can increase it.

Tendinopathy – Modern term for what used to be called tendinitis. Recognizes that tendon problems are often degenerative, not just inflammatory. Changes treatment approach.

Fascia – Connective tissue surrounding muscles. Becomes less pliable with age; why mobility work and proper warm-ups become more important.

Cognitive Reserve – Brain’s ability to maintain function despite aging. Regular aerobic exercise like easy running is one of the best ways to build it.

Frailty – Medical syndrome of decreased strength, endurance, and physiologic function. Running is one of the best preventions, but only if done sustainably.

Balance Confidence – Your belief in your ability to maintain balance during activities. Declines with age; trail running and varied terrain can help maintain it.

Metabolic Syndrome – Cluster of conditions (high blood pressure, blood sugar, excess belly fat) that increase disease risk. Easy running addresses all components better than intense exercise.

Mitochondrial Function – How well your cellular “powerhouses” work. Declines with age but responds well to consistent aerobic exercise. Another reason easy running works better than constant intensity.

Microbiome – Gut bacteria that affect everything from immunity to mood. Exercise helps maintain diversity, but stress (including overtraining) can harm it.

Running Real – Term for honest, sustainable running that acknowledges your actual abilities and circumstances rather than chasing fantasies.
