Spectro.Life calculates your race potential and helps you create a mathematically optimised race plan for pacing, nutrition and hydration based on your athlete profile and other personal preferences.

During onboarding, you have the option to manually create your athlete profile or connect your Garmin or Coros accounts. If you choose to connect your accounts, Spectro.Life downloads your activities from the past 90 days and uses this data to calculate your current fitness, fatigue, form, maximum tolerable fatigue, endurance, ascent and descent capabilities, and more. This profile is continuously updated with each new activity downloaded, ensuring that your plan remains personalised and up-to-date.
