How to Use This Calculator
  1. Enter your Swim Pace without a wetsuit per 100m in seconds.
  2. Set your Body Weight in kilograms.
  3. Select the Wetsuit Thickness in millimeters (3mm for warm water, 5mm+ for cold).
  4. Review the estimated Pace with Wetsuit, Pace Improvement, and Improvement %.
  5. Check Time Saved per 1000m, 1500m, and 3800m to estimate race time benefits.

What each input means

Swim Pace Without Wetsuit
Your current swim pace per 100m without a wetsuit. Use your recent pool or open water time.
Body Weight
Your body weight in kilograms. Heavier swimmers tend to benefit more from wetsuit buoyancy.
Wetsuit Thickness
Neoprene thickness in millimeters. Triathlon wetsuits range from 1.5mm to 5mm. Thicker = more buoyancy but less flexibility.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Swim Pace Without Wetsuit = 105, Body Weight = 75, Wetsuit Thickness = 3 = 3 input(s) provided
  2. Calculate Estimated Pace with Wetsuit
    Estimated Pace with Wetsuit
    101.2 = 101.2
  3. Calculate Pace Improvement
    3.8 = 3.8
  4. Calculate Improvement
    Improvement = adjustedImprovementPct
    3.6 = 3.6
