Welcome to the Spring 2021 Sprint Orienteering Series! We are bringing back the tradition of the CSU Park-O series that would have had its 20th year in 2020 (except for 2020!). This year the spring series will be 5-6 low-key, short course, in-person events in local urban parks.

Please note that pre-registration is required for all events no later than the Tuesday (2 days) before. Reserve your spot now for the series or sign up weekly (space dependent). Due to Covid-19 restrictions we have a limit of 50 participants for some locations, and we will print maps based on pre-registration. 

Further information and registration: Thursday Evening Spring Sprint Orienteering 2021

As these events are organized jointly by Cambridge Sports Union (CSU) and New England Orienteering Club (NEOC), the NEOC membership will not cover start fees ($5/event or $15/series; family discount available).
