Summer Race Sharpener
Winter built the engine. Now make it fast. This twelve-week plan takes a big aerobic base and sharpens it into race speed, then peaks you for a target regatta or 2k. It follows the way fitness is actually built to a peak: raise your threshold first, add race-pace and VO2 work where the real speed is made, then taper so all of it surfaces fresh on race day.
Every pace is set from your current 2k, so it fits any level with a base in place. Two easy days each week keep the base topped up while the sharp work does its job, and a plain-English science section explains the pacing and the taper - each point cited. It assumes you arrive with a base (ideally from the Winter Base Builder); you cannot sharpen an engine you have not built.
