1. What is Swim Pace?

Swim pace is the time it takes to swim a standard distance (typically per 100 meters or 100 yards). It's a crucial metric for triathletes to gauge their swimming speed and plan race strategy.

2. How Does the Calculator Work?

The calculator uses the simple pace formula:

\[ P = \frac{T}{D} \]

Where:

Explanation: For example, if you swam 3800m in 76 minutes, enter 76 for time and 38 for distance (3800m = 38 × 100m).

3. Importance of Pace Calculation

Details: Knowing your swim pace helps with race planning, pacing strategy, and tracking performance improvements over time. For Ironman, typical swim distances are 3.8km (2.4 miles).

4. Using the Calculator

Tips: Enter total swim time in minutes and distance in 100m/100yd units. For Ironman swim (3.8km), use 38 as the distance value.

5. Frequently Asked Questions (FAQ)

Q1: What's a good Ironman swim pace?
A: For age groupers, 1:30-2:00 min/100m is typical. Elite swimmers may be under 1:15 min/100m.

Q2: Should I use meters or yards?
A: Use whichever unit matches your pool training. Ironman courses are in meters (3800m).

Q3: How does pool pace compare to open water?
A: Most swimmers are 5-15 sec/100m slower in open water due to conditions, drafting, and navigation.

Q4: How to improve swim pace?
A: Focus on technique first, then build endurance with interval training and open water practice.

Q5: What pace should I target for my goal time?
A: For a 1 hour Ironman swim (3800m), you'd need 1:35 min/100m pace (60min/38 = ~1.58).
