Running the same pace every day? Thatâs killing your progress.
To become a stronger, faster, more efficient runnerâyou need to mix up your training. Each type of run plays a unique role in your development:
⸝
1. Slow Runs (Zone 2)
Your easy, aerobic-paced runs. These strengthen your heart, build endurance, and improve fat metabolismâall while keeping stress low.
Theyâre the foundation of any smart training plan.
Why they matter:
Skip these, and you risk burnout or injury. Build your engine first.
⸝
2. Tempo Runs
These runs combine a mix of easier running with sustained efforts at a âcomfortably hardâ paceâtypically what you could hold for 45â60 minutes. You might ease in with a few miles at an aerobic pace, then shift into your tempo pace to finish strong. This trains your body to stay efficient under fatigue while improving stamina and pacing control.
Why they matter:
Tempo runs teach you how to control effort, build fatigue resistance, and finish fastâkey for race-day ex*****on.
⸝
3. Lactate Threshold Runs
Similar to tempo runs but slightly more intense. These are run right at your lactate thresholdâthe point just before fatigue takes over. They help your body clear lactate efficiently while holding a strong, controlled pace.
Key difference:
Tempo = steady, moderate discomfort
Threshold = controlled edge of discomfort
Why they matter:
They raise the ceiling of what you can sustain before fatigue sets inâcrucial for racing faster.
⸝
4. Speed Work
Short intervals (200â800m) at fast paces to improve turnover, explosiveness, and form. Think strides, hill sprints, or intervals at 5K pace or faster.
Why they matter:
Speed work improves your top-end speed and running economyâso your race pace feels easier.
⸝
Each run targets a different system. Together, they build endurance, strength, and speed.
Want help building a custom plan that blends all 4 run types for maximum results?

Sunday long run â
20-miler in the wind đ¤
I love this S**t âźď¸đ

Crushed todayâs 12-mile run. Itâs been a while since Iâve been able to push this pace at a longer distance not to mention in 21mph winds. But I know itâs only going to be beneficial come race day. Just about 9-weeks out until the SF Marathon. Week by week progress. Staying focused and trusting the process đ¤

Lifting doesnât make runners slower â it makes them faster.
Strength training builds power, stability, and durability.
It helps you:
â˘Builds stronger muscles for longer miles and less fatigue
⢠Run more efficiently
⢠Boost stride power
⢠Fix imbalances before they cause problems
â˘Injury prevention
Itâs not about bulk â
Itâs about resilience.
You donât need less strength â
You just need to train correctly.
Stop skipping the weights.
Start running stronger, longer, and pain-free.

Why Speed Work Matters
Training for a race? Donât just log slow miles. Speed work builds the foundation for real breakthroughs no matter the distance.
1ď¸âŁ Improves Running Economy
Speed workouts like intervals and strides improve how efficiently your body uses oxygen. You train your muscles and nervous system to fire more effectively, so you can hold your pace longer, without burning extra energy.
2ď¸âŁ Builds Mental Toughness
Running fast forces you into discomfort and teaches you how to stay calm there. Speed sessions train your brain to focus, manage effort, and push through when your legs want to give up, just like youâll need to do in the final miles of a race.
3ď¸âŁ Raises Your Lactate Threshold
When you train at threshold pace a âcomfortably hardâ effort, your body learns to tolerate and clear lactic acid better. That means you can maintain a challenging pace for longer without slowing down or blowing up mid-race.
4ď¸âŁ Activates Fast-Twitch Muscle Fibers
Endurance training mainly hits slow-twitch fibers great for long runs. But to finish strong, handle surges, and power up hills, you need fast-twitch activation too. Speed work balances your muscle recruitment, making you more explosive and injury-resilient.
5ď¸âŁ Sharpens Race-Day Gears
Practicing different paces, especially your goal pace or faster builds rhythm, confidence, and pacing awareness. You learn what each effort level feels like, so you donât go out too fast or panic when it gets hard.

Your bodyâs always talkingâfatigue, tightness, lingering aches⌠thatâs feedback, not failure.
Ignore it, and you risk setbacks.
Listen, and you build resilience.
Pushing past your limits every day doesnât build strengthâit builds burnout.
A lighter week of training isnât a setbackâit builds momentum for the weeks ahead.
Listening to your body isnât weaknessâitâs a strategy!
Train hard. Recover harder. Longevity always wins.
