In the Speed Power Profile, which color represents a 1:1 rest-to-work ratio?

• A. Green; 1:1 ratio
• B. Red; high rest 1:5
• C. Yellow; low rest
• D. Blue; no rest

Answer: (A)

The Speed Power Profile uses color to show how long you rest compared to how long you work during intervals. Green represents a 1:1 rest-to-work ratio, meaning the rest duration is equal to the work duration. So if you sprint for a certain time, you rest for the same amount of time.

That pattern contrasts with other colors: red signals a high-rest setup (roughly 1:5, where rest is much longer than work), yellow indicates low rest (shorter rest than work but not none), and blue means no rest between efforts. The color coding helps you quickly grasp the pacing you’re supposed to use.

So the color green is the one that represents a 1:1 rest-to-work ratio.
