VO₂ Max Testing for Triathletes in Santa Cruz

Comprehensive tri-specific data for both bike and run:

• Bike Testing (Wahoo KICKR) Provides:
  • • Cycling VO₂ Max: Your aerobic capacity on the bike
  • • Power-to-HR Correlation: Map watts to heart rate at every zone
  • • True FTP: Lactate threshold power (not just 20-min test × 0.95)
  • • 5 Bike Zones: Recovery, endurance, tempo, threshold, VO₂ max
  • • Substrate Use: Fat vs. carb burning at race pace (fueling strategy)
  • • Pacing: Exact HR/power for Sprint (Zone 4 to 5), Olympic (Zone 4), 70.3 (Zone 3), IM (Zone 2 to 3)
• Run Testing (Treadmill) Provides:
  • • Running VO₂ Max: Your aerobic capacity running
  • • 5 Run Zones: Recovery, easy, tempo, threshold, VO₂ max
  • • True Threshold: Lactate threshold HR and pace
  • • Running Economy: Oxygen cost at different paces
  • • Run-Off-Bike Guidance: Adjust zones for fatigued running after bike leg
  • • Pacing: Exact HR for Sprint (Zone 5), Olympic (Zone 4), 70.3 (Zone 3 to 4), IM (Zone 3)
• Multi-Sport Insights:
  • • HR Drift: Expect 5 to 10 bpm increase from bike to run at same perceived effort
  • • Transition Strategy: Start run 10 bpm BELOW normal Zone 3, let HR rise naturally
  • • Fueling: Stay in fat-burning zone on bike to preserve glycogen for run
  • • Pacing: Bike slightly easier than standalone cycling race to save legs for run

Zone-based pacing strategy for every triathlon distance:

• Sprint Distance (750m swim / 20K bike / 5K run):
  • • Bike Pacing: Zone 4 to 5 (85 to 95% max HR, 90 to 105% FTP)
  • • Run Pacing: Zone 5 (90 to 100% max HR, near VO₂ max)
  • • Duration: 55 to 90 minutes total (elite to age-group)
  • • Strategy: High-intensity throughout, limited pacing conservatism needed
  • • Training Focus: Zone 4 to 5 intervals, threshold work, speed
• Olympic Distance (1.5K swim / 40K bike / 10K run):
  • • Bike Pacing: Zone 4 (80 to 90% max HR, 85 to 95% FTP)
  • • Run Pacing: Zone 4 (85 to 90% max HR, threshold pace)
  • • Duration: 2 to 3 hours (elite to age-group)
  • • Strategy: Steady threshold effort on bike, controlled-aggressive run
  • • Critical: Bike at upper Zone 4 = fine. Zone 5 on bike = run blows up!
  • • Training Focus: Zone 4 threshold intervals, tempo runs
• Half Ironman / 70.3 (1.9K swim / 90K bike / 21.1K run):
  • • Bike Pacing: Zone 3 (75 to 85% max HR, 75 to 85% FTP)
  • • Run Pacing: Zone 3 to 4 (80 to 87% max HR, tempo to threshold)
  • • Duration: 4 to 7 hours (elite to age-group)
  • • Strategy: Conservative bike (save legs!), progressive run if feeling good
  • • Common Mistake: Bike at Zone 4 = death march on run at mile 8!
  • • Training Focus: Zone 2 base + Zone 3 tempo, brick workouts
• Full Ironman (3.8K swim / 180K bike / 42.2K run):
  • • Bike Pacing: Zone 2 to 3 (70 to 80% max HR, 68 to 78% FTP)
  • • Run Pacing: Zone 3 (75 to 82% max HR, "comfortably hard")
  • • Duration: 9 to 17 hours (elite to age-group)
  • • Strategy: EXTREMELY conservative bike (it's a bike ride with a marathon attached!)
  • • Critical Truth: Bike at Zone 3 = runnable marathon. Bike at Zone 4 = walking by mile 15!
  • • Training Focus: Massive Zone 2 volume, long bricks, fat oxidation optimization

The dreaded transition from bike to run-how to nail it:

• Why Running Off the Bike Is Harder:
  • • Muscle Fatigue: Quads trashed from cycling = altered running gait
  • • Glycogen Depletion: Bike leg burns through carbs = less available for run
  • • HR Elevation: Already elevated HR from bike = feels harder to run
  • • Neuromuscular Fatigue: Different movement pattern after hours of cycling
• The First Mile Strategy (CRITICAL!):
  • • Start 10 to 15 bpm BELOW target zone
  • • Example: If goal = Zone 3 (150 bpm), start at 135 to 140 bpm
  • • Why: HR will naturally drift UP as you settle into run rhythm
  • • Mile 1: Feel awkward, let legs "wake up"
  • • Mile 2 to 3: HR settles into target zone, rhythm improves
  • • Result: Sustainable pace instead of blowing up in first 3 miles!
• Brick Workout Training:
  • • What: Bike immediately followed by run (simulate race)
  • • Frequency: 1 time every 1 to 2 weeks during build phase
  • • Example: 60 min bike @ Zone 2 to 3 → 20 min run @ goal race pace
  • • Purpose: Teach body to run on tired legs, practice HR management
  • • VO₂ Max Benefit: Know EXACTLY what HR to target in brick run based on testing

Santa Cruz offers perfect multi-sport training for triathletes:

The Santa Cruz Triathlete Advantage: Year-round training weather, sea-level swimming (warm up for races), diverse bike terrain, great running routes, active tri community, perfect testing location.

Your substrate utilization (RER) data informs nutrition strategy:

• Sprint & Olympic Distance:
  • • Intensity: Zone 4 to 5 (primarily carb-burning, RER >0.90)
  • • Fueling: Pre-race carb load, minimal in-race fueling needed (short duration)
  • • Strategy: Water/sports drink on bike, maybe 1 gel
• 70.3 Distance:
  • • Intensity: Zone 3 (mixed fat/carb, RER 0.85 to 0.90)
  • • Bike Fueling: 60 to 80g carbs/hour (gels, bars, sports drink)
  • • Run Fueling: 30 to 60g carbs/hour (gels every 20 to 30 min)
  • • Testing Benefit: Know your fat oxidation rate-stay in fat-burning zone on bike!
• Ironman Distance:
  • • Intensity: Zone 2 to 3 (heavy fat oxidation, RER 0.75 to 0.85)
  • • Bike Fueling: 60 to 90g carbs/hour (spread evenly)
  • • Run Fueling: 30 to 60g carbs/hour (whatever stomach tolerates)
  • • Critical: Stay in Zone 2 on bike = maximize fat burning = preserve glycogen for run!
  • • Testing Shows: Your exact "FatMax" HR-stay near it on bike

Deciding which discipline(s) to test:

• Test Bike First If:
  • • Training for 70.3 or Ironman (bike = longest leg, biggest impact on race)
  • • You have a power meter (validate FTP, correlate power to HR)
  • • Pacing the bike leg is your main concern
  • • You struggle with going too hard on the bike
• Test Run First If:
  • • Training for Sprint or Olympic (run = relatively longer leg)
  • • Run pacing is your weakness (go out too fast)
  • • You want to optimize run-specific training
  • • Coming from running background, want precise zones
• Test Both If:
  • • You want complete multi-sport data (ideal for serious triathletes!)
  • • Training for major race (IM, 70.3, Olympic championship)
  • • Budget allows ($500 total for both tests)
  • • You're a data-driven athlete optimizing every detail
