  • Interval Excellence: Interval training is the secret weapon in every triathlete’s arsenal. Embrace workouts that challenge your lactate threshold and boost your VO2 max, such as 400m repeats and pyramid intervals. These sessions not only enhance your speed but also fine-tune your race pace instincts.
  • Long Run Philosophy: Long runs serve as the cornerstone of your endurance foundation. Gradually increase your mileage to prepare your body for the rigors of race day, and don’t shy away from incorporating progression runs or fast-finish long runs to simulate race conditions.
  • Hill Mastery: Triathletes thrive on adversity, and hill training is where champions are forged. Integrate hill repeats and strength-building hill workouts into your regimen to strengthen your legs, improve running economy, and conquer any course terrain with confidence.
  • Speed Work Wisdom: Unlock your full potential by embracing the need for speed. Strides, accelerations, and form drills refine your biomechanics and unleash your raw power, ensuring that you glide effortlessly across the pavement when it matters most.
  • Brick Workouts: Skip this if you’re gunning the goal in a run-only race.  Transition seamlessly from the bike to the run with brick workouts. Incorporate bike-to-run sessions into your training plan to simulate the race day experience and adapt your body to the unique demands of running off the bike.
  • Saddle Time: If you’re gunning for an off-the bike run pr, don’t neglect the bike leg of your triathlon journey. Dedicate time to saddle sessions to build cycling endurance, power, and efficiency. Incorporate a mix of long rides, hill climbs, and interval workouts to strengthen your cycling legs and improve overall race performance.
  • Strength Training Supremacy: Elevate your performance to new heights by incorporating strength training into your regimen. Focus on exercises that target the legs, core, and stabilizing muscles, such as squats, lunges, deadlifts, and planks. Strengthening these key muscle groups enhances your running efficiency, reduces the risk of injury, and improves overall athletic performance.
  • Mobility Work and Recovery Rituals: Enhance your range of motion and prevent injuries with targeted mobility work. Incorporate dynamic stretches, foam rolling, and mobility exercises into your warm-up and cool-down routines to improve flexibility, joint stability, and running mechanics.  Just as the body adapts and grows stronger during training, it rejuvenates and repairs during periods of rest. Prioritize recovery with proper nutrition, hydration, and ample sleep to optimize your training adaptations and reduce the risk of injury.
  • Mental Toughness Training: The mind is a triathlete’s greatest asset. Cultivate mental toughness through visualization, positive self-talk, and race simulation workouts. Harness the power of the mind to conquer doubts and propel yourself towards victory.
  • Race Day Execution: Execute your race strategy with precision and poise. Trust in your training, stay disciplined with your pacing, and embrace the exhilarating challenge of pushing beyond your limits to achieve your sub-hour 10km dream.
