This session is a great way to check in on your training progress and build endurance at different effort levels.
Warm-Up & Drill Focus
• Start with an easy warm-up.
• Choose one drill—preferably a challenging one that will help you get the most improvement.
Main Set: Pacing Challenge
You’ll swim a series of 100s or 50s, going through the set three times, increasing effort each round:
1️⃣ Round 1 – 60% Effort
• Swim nice and slow—this should feel comfortable.
• Either set a goal time or time your first one.
• Take 10 seconds rest and stick to this same cycle for all repeats.
2️⃣ Round 2 – 70% Effort
• Pick up the pace—aim to swim about 5 seconds faster per 100m.
• Keep the same 10-second rest between repeats.
3️⃣ Round 3 – 80% Effort
• Now it’s time to push! This should be a strong, confident pace.
• Maintaining this speed with just 10 seconds rest will be a challenge—go for it!
This session will test your ability to hold speed under fatigue, so stay focused, pace yourself well, and push through!
