Alan Couzens, MSc

Alan Couzens is an exercise physiologist and endurance coach with 25+ years of experience coaching professional and age-group athletes. He runs the MAD Crew (Maximum Athletic Development) community and has coached athletes to world championship podiums.

For Project Unreasonable, Alan designed the complete 12-month periodized training plan targeting a CTL of 90 by race day. His key insight: if John can sustain a ramp of +8 CTL per month — at the upper limit of what's physiologically possible — a sub-3:20 marathon comes within range.

Data-driven, evidence-based. CTL modeling, efficiency factor tracking, metabolic testing. Every training decision backed by numbers. The math says it shouldn't be possible — but the math also shows a path.
