Please use this calculator to determine your targets for Ironman Lake Placid. The race calculator uses your weight, watts per kg, VI and a target TSS score to estimate your bike split based on our athletes’ performance on the Ironman Lake Placid course. The calculator only roughly takes into account the aerodynamics of the bike and the rider (more accurate data can be attained by having your coach calculate your CdA via Best Bike Split), and is not a guarentee of performance. It should be used in conjunction with your coach, who knows you best, to determine a fueling and pacing strategy.
Stress Calculator: Determines target watts based on a designated level of fatigue.
Time Calculator: Determines target watts based on a targeted bike split.
Note: We recommend first using the stress-based calcutor to determine your target watts, then using the time calculator to see how changing your time affects your training stress score.
Hydration Calculator: Determines hydration rate and sodium requirements based on your sweat rate.
Carbohydrate Loading: Determines your target intake of macronutrients leading into the race.
