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

The Mary Cummings Park event is free, thanks to the Trustees. 

Organized by Cambridge Sports Union (CSU) and New England Orienteering Club (NEOC).
