Vol. I · Beta edition · Limited access

Your first
plan, Sunday
night.

"I'm still learning what your numbers mean. Use what I'm telling you as a starting point, and tell me when something's off."
Beta riders get a 12-week plan built to their event, a note from Mia every Sunday, and direct access to give feedback that shapes the product. No polish. Honest coaching.
