What this race demands

The Henley Classic demands sustained aerobic endurance and mental focus to complete a 2.1-kilometer open-water swim upstream.

Upstream resistance

Swimming against the current over a 2.1-kilometer distance requires continuous muscular effort and an efficient stroke to maintain forward progress.

Aero-aerobic capacity

The open-water swim format demands steady-state cardiovascular output sustained continuously from start to finish without resting intervals.

Race day at Henley Classic is 44 weeks away. This is how a coach divides that time. The first phase starts now.
