The Great Pyramid was built with incredible precision, and in this challenge, precision is crucial to a successful finish. Here's the challenge breakdown: • Thirteen (13) continuous minutes (no rest). • Every split is one minute long (1:00). • Rate changes every minute, following this pyramid sequence: 18-20-22-24-26-28-30-28-26-24-22-20-18. • 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. Scoring: This challenge has a maximum of 13 points. Earn 1 point for each split you repeat the same SPI as the first minute at the prescribed rate. Disclaimer: • You must finish the 1st split at 18 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. TIP: While you may choose to monitor any metric during the challenge, we recommend keeping a close eye on stroke count and watts. 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.
