Whaleback Mountain hosts the Upper Valley’s most popular Adult Ski Race League under the lights on Thursday nights with a head to head dual Slalom! Whether you are a returning racer, just getting into racing or an ex-olympian, this is the race league for you. Teams of four people will race each week (one team member must be of the opposite sex). If a member of your team is unable to make it, a substitute may be used. This is a head-to-head race, with teams racing side-by-side each week. Teams have the opportunity to accumulate a maximum of 8 points per night. Prizes are awarded weekly thanks to our sponsors.
