Should Triathletes’ Run Training Differ from Elite Runners’ Training? • Comparison of physiological demands • Comparison of athletes and training • Which physiological variables matter? • Implications for training • Can swimming/cycling replace running mileage? • Individuality • Mistakes to avoid
How do the Physiological Demands of O.D. Triathlon compare to 10,000M/1/2 Marathon?
How do the Physiological Attributes of the Athletes Compare?
Which Physiological Variable is the Best Predictor of Running Performance? • Best predictor of performance = pace @ LT (lactate + economy)
Implications for Triathlon Run Training • Strategies to reduce difference from optimal conditions at start of run • Train to improve lactate threshold • Train to improve running economy (running only & off the bike) • Use “creative periodization” to accomplish these objectives
Reducing Differences from Optimal Conditions @ Run Start • Excellent cycling fitness, to reduce relative demand • Strategic effort on bike (team-work, high cadence) • Controlled first km run • Carbohydrate/fluid intake
Training to Improve Lactate Threshold • Peripheral adaptations ( capillarization, mitochondria, aerobic enzyme activity, etc.) in muscle, which lactate accumulation ( formation/ clearance) • Greatest stimulus to improve LT is to train at or slightly above LT effort • LT Pace = ~15 km race pace =~One hour race pace = 10 km race pace +~10 seconds/km • Tempo runs (20-45 min) or cruise intervals (5-15 min with short recovery) • Increased running volume helps too
Training to Improve Running Economy (run only) • Accumulated running experience/volume • Improved technique (drills) economy • Maintenance of technique (drills and core stability) economy • Increased strength (wtlifting) may economy • Hill running may economy • Tapering economy • Economy is specific to speed and terrain
Training to Improve Running Economy off the Bike • Cycling must be strong so athlete can run well off the bike = bike racing fitness • Strategies to run close to “fresh” 10 km pace = Sustained fast running when fatigued • Bricks (discussed shortly) • Run hills followed by intervals (brick without the cycling) • Fatigue legs with exercises (e.g. burpees) before intervals • Long drills to maintain technique
How Important are Bricks in Improving Running Economy off the Bike? • Highest specificity for racing • Insert hard brick sessions carefully due to recovery requirement • Periodize, but include some type of brick year-round • What types of bricks are optimal at different stages of preparation?
Do Swimming & Cycling Training Improve or Hinder Running Performance? • Positives: • Swimming & cycling improve cardiovascular fitness with less risk of injury than additional running • Swimming & cycling help recovery • Negatives: • Lactate threshold and running economy improve due to peripheral adaptations in the muscles (lack of specificity) • Cycling tends to develop tight hip flexors and hamstrings • Cycling may overdevelop quads • Swimming and cycling increase overall fatigue
Implications for Triathlon Run Training • Replacing “non-specific junk miles” with swimming and cycling develops general aerobic fitness & helps recovery • Effects of increased running volume in developing peripheral adaptations cannot be replaced • Cannot substitute specific run training to improve LT and economy
Designing Training for Different Stages of Development • Large differences between triathletes in ability to adapt positively, depending on: • Biological/training age (changing canvas) • Gender • Genetics (“Plumbing” and “Adaptability”) • Injury history • Biomechanics • Some young swimmers have bone density • Volume/intensity dictated by current ability to adapt positively (increase 10-25%/yr?)
Mistakes to avoid: • Ramping up running volume or intensity too quickly (or at same time = stress fractures) • Emphasizing specific sessions and speedwork before building up a big aerobic base • Charging out of transition as though racing 3km (invariably leads to slower time) • Not taking steps to improve poor running technique • Training O.D. triathletes like 5,000m runners (lower mileage/more speedwork) • Not progressing training from year-to-year
