Real-Time Sprint Performance Tracking for iOS and watchOS.
Sprint Coach 40 is your personal 40-yard dash training coach. Whether you're training for football combines, track tryouts, or just want to get faster, we've got you covered.
We recommend 2-4 sessions per week. More isn't always better — quality and recovery are crucial for speed development.
Our structured program follows a proven periodization model with four phases:
Base Phase (Weeks 1-3)
Build foundation with technique work and moderate volume
Build Phase (Weeks 4-6)
Increase intensity and volume for strength development
Peak Phase (Weeks 7-9)
Maximum intensity, lower volume for peak performance
Recovery Phase (Weeks 10-12)
Active recovery and preparation for next cycle
Create custom workouts with your own distance, reps, and rest periods. Perfect for experienced athletes or specific training needs.

What is Sprint Coach 40?
Sprint Coach 40 is a professional sprint training app designed to help athletes improve their 40-yard dash time through GPS-tracked workouts, structured training programs, and real-time coaching.
Do I need any special equipment?
You need an iPhone with GPS and optionally an Apple Watch for heart rate monitoring. Sprint spikes, a track, or open field are recommended but not required.
Is Sprint Coach 40 suitable for beginners?
Yes! Sprint Coach 40 offers programs for all experience levels from beginner to elite. During onboarding, you'll select your experience level and the app will personalize your training accordingly.
How accurate is the GPS tracking?
GPS accuracy is typically within 3-5 meters. For best results, use Sprint Coach 40 in open areas with clear sky visibility. Indoor tracks or areas with tall buildings may reduce accuracy.
Do I need an Apple Watch to use Sprint Coach 40?
No, Apple Watch is optional. Sprint Coach 40 works great on iPhone alone. However, an Apple Watch provides additional features like heart rate monitoring, wrist-based controls, and the ability to leave your phone behind during workouts.
How do I sync my Apple Watch with Sprint Coach 40?
Sprint Coach 40 automatically syncs with your Apple Watch when both devices are paired and the Watch app is installed. Your profile, training programs, and workout history sync automatically.
Can I start workouts from my Apple Watch?
Yes! Open the Sprint Coach 40 Watch app, select your training program, choose a workout, and start training directly from your wrist. All data syncs back to your iPhone automatically.
Does the Watch app work without my iPhone nearby?
Yes, if you have a cellular Apple Watch. The Watch app can track workouts independently using its built-in GPS. Data will sync to your iPhone when they reconnect.
Why isn't my heart rate showing during workouts?
Ensure you've granted HealthKit permissions in Settings → Health → Data Access & Devices → SC40. Also check that your Watch is worn snugly on your wrist for accurate readings.
How long are the training programs?
The 40 Yard Program is a structured 12-week cycle divided into 4 phases: Base, Strength, Power, and Peak. Each phase focuses on different aspects of sprint performance.
How many days per week should I train?
You choose your training frequency during onboarding (1-7 days/week). We recommend 3-4 days for most athletes, with rest days for recovery. Elite athletes may train 5-6 days per week.
Can I customize my workouts?
Yes! Use Sprint Timer Pro to create custom workouts with your choice of distance (10-100 yards), reps (1-10), and rest intervals (1-10 minutes).
What if I miss a workout?
Don't worry! You can continue from where you left off or restart a week if needed. Consistency is important, but occasional missed workouts won't derail your progress.
Why isn't GPS working?
Ensure Location Services are enabled: Settings → Privacy → Location Services → SC40 → While Using. Also make sure you're outdoors with clear sky visibility.
How do I reset my data?
Go to Settings → Danger Zone → Reset All Data. WARNING: This permanently deletes all your workouts, progress, and profile data.
Can I export my workout data?
Yes! Use the Share Performance feature to generate detailed reports with your workout history and athlete profile. You can share via text, email, or save as PDF.
Does SC40 integrate with Apple Health?
Yes! SC40 can read heart rate data from HealthKit and optionally save your workout data to the Health app.
How do I enable voice coaching?
Voice coaching is enabled by default. You can toggle it in Settings → Workout Settings → Voice Coaching. Make sure your device volume is turned up.
What should I do if the app crashes?
Try restarting the app and your device. If issues persist, contact support at support@accel-8.com with details about when the crash occurred.
