WHO IS STEALTH FOR?

Stealth is for committed age-group athletes who:

• Have an A-race they are serious about targeting
• Want high-level structure without paying £200+/month for 1:1 coaching
• Have busy lives and need training that respects work and family time
• Want to understand the biomechanics and sports science behind their training
• Are ready to show up consistently and execute

WHAT STEALTH IS NOT:

Stealth is not 1:1 bespoke coaching.

It is not for athletes who require daily individual calendar shuffling or personalised 1-on-1 calls every week.

Plans are structured pathways rather than fully custom day-by-day programs.

(If you require 1-on-1 plan changes and personal data analysis, Stealth Plus provides that dedicated tier).
