STIMULUS
- Overview: This interval-based cardio workout pre-fatigues you with a bike + run before you return to the bike for a hard push to finish out each interval. With equal rest, look to push the pace while aiming for consistency across the 4 rounds.
- This Target Tuesday workout is part of a 5-week series leading to improvements in compromised running to assist you in the next benchmark workout, βEndureβ in the first week of May.
- Choose an initial bike calorie number and run distance that gives you at least 1 minute on the bike at the end of each round.
- Scoring: Your score is the total number of calories of your bike in remaining time (the first bike calories each round don't count towards your score).
- Intended Intensity: RPE 7-8
- Fitness Attribute Improved: Aerobic Power [VO2 Max]
- Target Score: 60-100 Calories (M), 48-80 Calories (W)
STRATEGY
- Approach the opening bike at a strong pace that doesn't force you to slow down your run.
- Settle quickly into your run pace, focusing on a fast cadence over long strides.
- Get back onto the bike immediately and get it moving. Assuming you have at least a minute here, use the first 10-15 seconds to settle, then increase your effort. The final 30 seconds should feel like a controlled sprint. With a full 4 minutes of rest between efforts, you can afford to push hard at the end of each interval.
