Corral / Wave Start
A system that groups runners by expected finish time to reduce congestion at the start line and improve safety.
What is a Corral?
A corral is a designated starting area that groups runners by their expected finish time. Faster runners start in front, slower runners start behind, with barriers separating each group.
How It Works
Assignment
When you register, you provide:
- A qualifying time (from a recent race), or
- An estimated finish time
Based on this, you're assigned a corral (A, B, C... or 1, 2, 3...).
Race Day
- Each corral has a specific gathering area
- Gates or barriers separate corrals
- Corrals are released in waves, often 5-15 minutes apart
Why Corrals Exist
Safety
- 🚶 Prevents stampede-like starts
- 👥 Reduces dangerous crowding
- 🏃 Avoids fast runners weaving through crowds
Fairness
- ⏱️ More accurate chip times for everyone
- 🏆 Fair competition within pace groups
- 😊 Better race experience for all speeds
Logistics
- 🚗 Reduces road closure time
- 🚧 Better course management
- 🏥 Easier medical coverage
Corral Etiquette
Do's
- ✅ Start in your assigned corral
- ✅ Arrive early enough to find your corral
- ✅ Seed yourself within the corral honestly
- ✅ Be patient during the release wait
Don'ts
- ❌ Sneak into a faster corral (you'll mess up others' races)
- ❌ Start in front if you're slower than others near you
- ❌ Push or shove when corrals merge
Wave Starts vs Rolling Starts
Wave Starts
- Groups released at specific times
- Clear separation between waves
- Common in large marathons
Rolling Starts
- Continuous flow across the start line
- Common in ultras and smaller races
- Less formal than wave starts
Sample Corral Structure
| Corral | Expected Finish | Pace (min/mile) |
|---|---|---|
| A/Elite | Under 3:00 | Under 6:52 |
| B | 3:00-3:30 | 6:52-8:01 |
| C | 3:30-4:00 | 8:01-9:09 |
| D | 4:00-4:30 | 9:09-10:18 |
| E | 4:30-5:00 | 10:18-11:27 |
| F | 5:00+ | 11:27+ |
What If You're in the Wrong Corral?
Too slow a corral?
- You'll catch and pass lots of people
- Your chip time will still be accurate
- It's annoying but not the end of the world
Too fast a corral?
- You'll slow everyone behind you
- You might get swept up in too-fast pace
- Please don't do this
Corral Gaming
Some runners try to "game" the system:
- Submitting fake qualifying times
- Transferring bibs from faster runners
- Sneaking through barriers
This is frowned upon and can result in disqualification.
Tips for Corral Starts
- 📍 Know your corral before race day
- ⏰ Arrive early - Corrals fill up and may close
- 🚶 Use the bathroom before entering
- 🧥 Wear throwaway clothes if waiting is cold
- 🎯 Don't rush the start - Let chip time do its job
Corrals exist so everyone can have a good race. Respect the system, seed yourself honestly, and focus on running YOUR race.
