Best Interval Workouts to Improve Speed on Hilly Trail Courses

Training for hilly trail courses requires a unique approach, as running on inclines demands not only endurance but also speed and strength. One of the most effective ways to enhance your speed and efficiency on these challenging terrains is through interval workouts. Here are some of the best interval training sessions specifically designed to help you conquer hills and improve your overall speed on hilly trails.

Hill Repeats

Purpose : Build strength and power while improving your running form on inclines.

How to Do It:

• Warm-Up : Start with a 10-15 minute jog on flat terrain to get your muscles ready.
• Find a Hill : Look for a hill that has a moderate to steep incline, ideally around 200-400 meters long.
• Workout :
  • Sprint up the hill at a hard effort (around 85-90% of your maximum effort).
  • Focus on maintaining good form: lean slightly forward, drive your knees up, and use your arms for propulsion.
  • Jog or walk back down to recover fully.
  • Repeat 6-10 times, depending on your fitness level.
• Cool Down : Finish with a 10-15 minute jog on flat terrain.

Fartlek Intervals

Purpose: Improve speed and adaptability by varying your pace over different terrains.

How to Do It:

• Warm-Up : Begin with a 10-minute easy jog.
• Workout :
  • Choose a hilly loop or a flat section that leads into a hill.
  • During your run, alternate between periods of fast running (30 seconds to 1 minute) and recovery jogging (1-2 minutes).
  • Use landmarks such as trees, rocks, or road signs to determine your sprinting segments.
  • Incorporate hills during the faster segments to mimic race conditions.
• Cool Down : End with a 10-minute easy jog.

Tempo Hill Intervals

Purpose : Build lactate threshold and improve sustained speed on inclines.

How to Do It:

• Warm-Up : Start with a 10-15 minute easy jog, gradually increasing your pace.
• Workout :
  • Find a hill with a gradual incline.
  • Run at a "comfortably hard" pace (around 75-80% of your max effort) uphill for 5-10 minutes.
  • Keep your effort steady and focus on maintaining good form.
  • Recover by walking or jogging back down for 2-3 minutes.
  • Repeat this 3-5 times, depending on your fitness level.
• Cool Down : Conclude with a 10-15 minute easy jog on flat terrain.

Short Hill Sprints

Purpose: Develop explosive power and running economy for short bursts of speed.

How to Do It:

• Warm-Up : Spend 10-15 minutes warming up with gentle jogging and dynamic stretches.
• Workout :
  • Select a steep hill approximately 100 meters long.
  • Sprint up the hill at maximum effort for about 20-30 seconds.
  • Walk back down for full recovery (2-3 minutes).
  • Complete 8-12 sprints, focusing on explosive starts and form.
• Cool Down : Finish with a 10-15 minute easy jog.

Ladder Intervals

Purpose: Mix different lengths and intensities to develop speed and endurance.

How to Do It:

• Warm-Up : Start with a 10-minute light jog.
• Workout :
  • Run a series of intervals at increasing distances on a hilly route:
    • 30 seconds at hard effort
    • 1 minute at moderate effort
    • 2 minutes at tempo pace
    • 1 minute at moderate effort
    • 30 seconds at hard effort
  • Ensure you include hills in each phase, adjusting your intensity according to the incline.
  • Take a 1-2 minute recovery jog between intervals.
• Cool Down : End with a 10-15 minute easy jog.

Downhill Intervals

Purpose: Enhance leg speed and recovery technique on declines, which can be just as challenging as climbing.

How to Do It:

• Warm-Up : Begin with a 10-15 minute jog on flat terrain.
• Workout :
  • Find a downhill section that is safe and not too steep (200-400 meters).
  • Sprint down the hill at a controlled pace, focusing on quick turnover and relaxed form.
  • Recover by jogging back up the hill slowly.
  • Repeat 5-8 times, paying attention to your landing and maintaining control.
• Cool Down : Finish with a 10-15 minute easy jog on flat terrain.

Conclusion

Incorporating these interval workouts into your training routine can significantly improve your speed and efficiency on hilly trail courses. By focusing on building strength through hill repeats, enhancing your speed with fartleks, and working on your endurance with tempo runs, you'll be better prepared for the challenges of the trails. Remember to listen to your body, allow for adequate recovery, and enjoy the journey of becoming a stronger, faster trail runner!
