**2020 UPDATE**
The Green Monster has addended our REFUND POLICY to accommodate for the uncertain times, as follows;

We will offer a 100% REFUND in the event the race is cancelled due to factors outside of our control (ie: COVID, Government mandates).

We will offer a 100% REFUND for registered participants whom need to cancel PRIOR to online registration ending on September 30th 2020 at 11:59 pm. If you decide to bail at any point after that date, NO REFUND will be available.

Worth noting: the race this year is limited to 200 RUNNERS and will likely reach capacity long before online registration closes in September! In the event it does, a wait-list will be generated on a first-come-first-serve basis.
