Shoulder Season Running: Spring and Fall Weather Mastery
How to handle the unpredictable weather of spring and fall running. Layering strategies, weather variability, and making the most of transition seasons.
Spring and fall are the best—and trickiest—running seasons. The same week can bring freezing mornings and warm afternoons. Here's how to master these unpredictable but rewarding seasons.
Why Shoulder Seasons Are Special
The Best Conditions
Shoulder seasons offer:
- Ideal temperature ranges more often
- Lower humidity than summer
- More daylight than winter
- Peak performance potential
The Challenge
But they also bring:
- Maximum day-to-day variability
- Morning-to-afternoon swings of 30°F+
- Unpredictable precipitation
- Gear decisions that change daily
Spring Running
The Spring Pattern
Spring weather typically:
- Cold mornings, warming afternoons
- Frequent rain/storm systems
- Rapid week-to-week warming
- High variability day-to-day
Spring Challenges
- One day needs shorts, next needs tights
- Morning layers aren't needed by afternoon
- Rain appears suddenly
- Pollen makes breathing difficult
Spring Strategies
- Check forecast day of, not just weekly
- Carry removable layers (arm warmers)
- Expect anything
- Have indoor backup for storms
Fall Running
The Fall Pattern
Fall weather typically:
- Cool mornings, mild afternoons
- Gradually shortening days
- More stable than spring
- Occasional cold snaps
Fall Challenges
- Daylight decreasing weekly
- First cold days catch you unprepared
- Race season = high stakes weather
- Wide morning/afternoon temperature gaps
Fall Strategies
- Run afternoons when possible (warmer)
- Get reflective gear ready before you need it
- Don't fight the cooling trend—embrace it
- Target your races in this prime window
Temperature Swings
The 30-Degree Problem
Common shoulder season scenario:
- 6am: 42°F
- 12pm: 72°F
What do you wear?
The Answer
Depends on when you run:
- Morning: Light layers, arm warmers, possibly gloves
- Midday: Shorts and T-shirt
- Evening: Maybe shorts, maybe arm warmers
Removable Layers Win
Arm warmers and light vests:
- Can start with, then remove
- Tie around waist or discard
- Let you adapt mid-run
- Essential shoulder season gear

Gear for Transition Seasons
Essential Pieces
Must-haves for shoulder seasons:
- Arm warmers: Temperature versatility

The "Maybe" Pile
Items you'll use sometimes:

- Weekly conditions can vary wildly
Racing in Shoulder Seasons
The Opportunity
Spring and fall races offer:
- Best performance conditions
- Ideal temperature ranges
- Lower humidity
- PR potential
The Risk
But weather can also:
- Swing unexpectedly
- Be different than training conditions

- Affect pacing strategy
Race Day Strategy
- Check forecast 48 hours out, finalize plans
- Bring options for warmer AND cooler
- Have A/B goals for different conditions
- Be ready to adapt
Daylight Management
Spring: Gaining Light
Spring daylight grows:

Fall: Losing Light
Fall daylight shrinks:

- Lunch runs may be only daylight option
- Don't wait until it's too dark
The Transition Points
Key dates to know:
- Daylight Saving Time changes
- Equinoxes (equal day/night)
- Plan around these transitions
Weather Checking Habits
Shoulder Season Frequency
Check weather more often:
- Night before: General plan
- Morning of: Specific decisions
- Before leaving: Final verification
- Conditions change rapidly
What to Look For
Key data points:
- Temperature at run time
- Precipitation probability
- Wind (more variable in transition seasons)
- Morning vs. afternoon conditions
Making the Most of It
