We hope you are all staying safe and healthy during this challenging time. Due to COVID-19, the City and County of Boulder have banned all events until June 15th. In hopes to still put on an event, we have made the decision to postpone the Boulder Rez Half Marathon. This decision was made in conjunction with the Boulder Reservoir, City and County Officials.

The 2020 Boulder Rez Half Marathon will be postponed to June 2021.
