Imagine a rate pyramid; flip it upside down. On this new challenge, we start at the highest rate, climb it down, and climb back up to finish. All that while keeping a consistent SPI. And there is more; you must do it as quickly as possible. How fast can you be while being consistent? Here are the details: • Thirteen (13) continuous minutes (no rest). • Every split is one minute long (1:00). • Rate changes every minute, following this pyramid sequence: 30-28-26-24-22-20-18-20-22-24-26-28-30 • You choose the wattage/pace for the initial split (first minute). • Your goal: replicate the same SPI (Stroke Power Index) for the subsequent 12 minutes. • Your second goal: do it as fast as you can. Scoring: Score 1: Match SPI of the 1st split Earn 1 point for each split you repeat the same SPI as the first minute (at the prescribed rate). Score 2: Overall Pace Disclaimer: • You must finish the 1st split at 30 SPM. Failing to do so will invalidate the whole workout. • This challenge is not rate-capped. Each minute must be completed at the designated rate. Deviating above or below will invalidate that split for the Score 1. TIP: While you may choose to monitor any metric during the challenge, we recommend keeping a close eye on stroke count, watts, and SPI. Engineering: To help you with targets, once you complete a split, the ErgZone app will calculate and display the required wattage for the next split. To see Target Watts, toggle the 500m column twice. Note: depending on your SPI, going one or two watts above the calculated wattage by ErgZone might result in the correct SPI.
