A  
Aid Station Strategically placed checkpoints along race courses, crucial for race day success.

They provide runners with essential support, including hydration, nutritional snacks, and first aid.

Altitude Training Altitude training involves exercising at high elevations, where the air is thinner and oxygen levels are lower, to improve an athlete’s endurance and performance.

This can be a crucial factor in achieving your fastest time.

B  
Base Layer Moisture-wicking garments worn close to the skin keep the runner dry and comfortable, reducing the risk of chafing and regulating body temperature during runs.
Buffer Zone A tactical approach in which runners intentionally reduce their pace before tackling challenging parts of a course. This helps conserve energy and maintain stamina.
C  
Cadence The number of steps a runner takes in a minute. A higher cadence is often linked to a more efficient, less injury-prone running form. Help runners move more smoothly and reduce the impact on their joints.
Chafing Skin irritation occurs when skin rubs against skin or clothing, and it is common in areas like the thighs, underarms, and nipples during running.

Wearing proper clothing and using lubricants can prevent this friction and protect the skin during long or intense workouts.

D  
Drop Bag A personal bag filled with gear, food, and other supplies a runner needs, left at specific locations along a race course for easy access during the event. This allows runners to replenish their supplies without carrying everything, ensuring they are well-prepared on race day.
Dynamic Stretching Stretching while moving is recommended as part of a warm-up to increase flexibility and reduce injury risk.

This is similar to active recovery in interval training.

E  
Elevation Gain The total height a runner climbs during a run indicates a trail’s difficulty level.

It helps runners gauge the physical demands of a route, as routes with significant elevation gain are more challenging and require greater strength and stamina.

F  
Fartlek A Swedish term “speed play” is a training method that mixes continuous running with interval training.

Allow runners to vary their pace across different terrains. Makes runners more adaptable to changing conditions.

G  
GPS Watch: This wearable device tracks distance, pace, and often elevation. It is invaluable for tracking progress and navigation during interval training sessions.
H  
Hydration Pack A specialized backpack or vest equipped with a water reservoir or bladder, allowing runners to carry a significant amount of water hands-free.

A convenient tube extends from the reservoir to the wearer’s mouth, enabling easy hydration.

I  
Incline Training Incline Training means running up hills to get stronger and last longer. It makes you faster, helps you run better on different terrains, and adds variety to your workouts.
J  
Joint Support Nutrition or gear, such as knee braces or compression socks, designed to protect joints during long runs.
K  
Kick A burst of speed towards the end of a race. Also, the term for the back part of a running shoe’s sole.
L  
Lacing Techniques Different lacing techniques can improve how shoes fit and provide extra support, helping to tackle unique foot problems.

Adjusting how you tie your shoes can enhance comfort and stability, addressing issues like high arches or wide feet.

M  
Minimalist Shoes Minimalist shoes are crafted to simulate the experience of running barefoot, featuring minimal cushioning and a flat profile.

This design encourages a more natural foot movement and stride during running.

N  
Negative Split Finishing a race stronger and faster than you started, known as a negative split, can lead to better results. This strategy boosts your overall pace.
O  
Overpronation When the foot rolls inward excessively upon landing, often addressed with specific types of running shoes.

When the foot rolls inward too much after touching the ground, it is a common issue that can be corrected with specially designed running shoes.
These shoes provide support and stability to counteract the excessive inward motion.

P  
Pace The speed at which a runner goes over a set distance, measured in minutes per mile or kilometer. It shows how quickly or slowly you’re moving.
Q  
Quick Drying Fabrics Quick-drying fabrics in running clothes pull sweat away from the skin and evaporate it fast. This technology keeps runners dry and comfortable, even during intense workouts.
R  
Recovery Run This slow, relaxed run aids muscle healing after an intense workout or race. It’s designed to speed up recovery while keeping the body active.
S  
Single Track Narrow trails that require runners to move in a single file, which is standard in trail running.
Strength Training Exercises to improve muscular strength and endurance are crucial for trail runners to prevent injuries.
T  
Technical Terrain Trails that require careful navigation due to obstacles like rocks, roots, and steep sections.
Trail Shoes These shoes have extra grip for running on rough outdoor paths. They’re made to handle the challenges of off-road terrain.
U  
Ultramarathon Any race longer than a traditional marathon distance (26.2 miles or 42.2 kilometers), often held on trails.

This is a test of endurance and strategy, where elite runners and ambitious amateurs push their limits.

V  
Vertical Oscillation Reducing the “bounce” in your step makes running more energy-efficient. Less bounce means smoother, more effective movement.
W  
Waterproof Jackets Waterproof Jackets are light and airy, designed to shield you from rain and wind without overheating. They keep you dry and comfortable in harsh weather.
X  
X-training (Cross-training) Engaging in various exercises besides running to improve overall fitness and reduce injury risk.
Y  
Yaktrax A brand of traction devices that can be attached to shoes for running on snow or ice.

Yaktrax are traction devices that clip onto shoes, providing extra grip for safely running on icy or snowy surfaces.

They help prevent slips and falls in winter conditions.

Z  
Zero Drop Shoes These shoes are even in height from the front to the back, encouraging a more natural landing with each step.

Favored by many elite runners for its potential to reduce injury risk and improve running efficiency.
