Mammoth Performance Development Series - Sundays 2027

About this event

Mammoth Mountain's Sunday Performance Development Series is a fixed 10-session adult ski-or-snowboard cohort running January 10 through March 21, 2027 from Main Lodge. It is not a drop-in weekly class: enrolled participants are expected to attend the full series, meeting from 9:00 AM to noon on each published date. Nine sessions are Sundays; the January 17 holiday-weekend session moves to Monday, January 18. There are no sessions on February 14. Mammoth positions the program for intermediate and advanced skiers and snowboarders ages 18 and older who want consistent small-group coaching, a stable peer group and an instructor who can follow their progress across the season. The mountain and terrain plan change week to week with group ability, weather, snow and operations; Mammoth says groups explore the mountain in search of the best available terrain and conditions. Friends may also assemble their own group and work with a personal instructor for the season, but the public page does not publish a minimum group size, group cap or private-group surcharge. The exact Main Lodge meeting point is emailed before the series and may move for weather. Lift access is excluded, so every participant needs a valid season pass or lift ticket for all 10 dates. At verification, the official page listed both Sunday and Wednesday start dates but its booking component returned No Results; TrickBook therefore records registration as not yet available rather than closed. No price, deadline, remaining-capacity count, waitlist, on-site enrollment or transfer rule is currently public. Mammoth's general activity-change policy is retained as guidance, with checkout-specific terms controlling when sales open. The current exact program page supplies a 2400x1350 hero showing a helmeted adult snowboarder receiving one-on-one coaching from a Mammoth instructor; it was visually reviewed and stored unchanged on TrickBook-controlled storage. Mammoth is outside the normal LA inventory radius and is included only under the major destination-mountain exception for a named 10-week progression program serving Southern California riders.
