30-Week Flat & Fast Long-Distance Triathlon Plan (140.6)
This 30-week Flat & Fast Long-Distance Triathlon Plan is designed for first-time athletes preparing for a predominantly flat, high-speed 140.6-distance event where pacing discipline, aerobic efficiency, and sustained output are critical to success.
The plan is ideally suited to flat or lightly rolling long-course triathlons similar in profile to events such as Barcelona, Florida, Texas, Copenhagen, Western Australia, Outlaw and other fast courses that reward steady power, aerodynamic efficiency, and controlled run pacing rather than climbing strength.
If your race features long straight bike sections, minimal elevation change, and a run course that rewards consistency and durability, this plan builds the fitness, execution skills, and confidence required for a strong, controlled race-day performance.
Written by Enduraprep Head Coach Lawrence Cronk, who has coached 100+ long-distance triathlon finishes — from complete first-timers to World Championship qualifiers — this plan delivers a proven, realistic, and sustainable progression tailored to busy age-group athletes targeting fast course profiles.
